OPINION OF THE COURT
BECKER, Circuit Judge.
This appeal from a judgment of the district court, dismissing on grounds of res judicata and the statute of limitations, a securities fraud suit, brought under the civil RICO statute and federal securities law, presents three interesting questions. First, we must determine whether a dismissal for failure to file a complaint within the time limit set by the state court constitutes a sanction and therefore a decision on the merits, in which case it is a basis for claim preclusion, or a dismissal for failure to prosecute, in which case it is not. Second, we must decide whether exclusive federal jurisdiction or concurrent jurisdiction exists over RICO claims. Under Pennsylvania law, if federal jurisdiction is exclusive, the state decision cannot act as a bar to litigation in the federal court. Third, we must consider whether this Court’s decision in In re Data Access Systems Securities Litigation, 843 F.2d 1537 (3d Cir.1988) (in banc), cert. denied, — U.S. —, 109 S.Ct. 131, 102 L.Ed.2d 103 (1988), which set a new standard for the determination of statutes of limitations for federal securities claims, should be applied retroactively.
For the reasons that follow, we hold that the dismissal was a sanction, that civil RICO jurisdiction is concurrent, and that Data Access should be applied retroactively given these facts. We therefore affirm.
I. FACTS AND PROCEDURAL HISTORY
On November 17, 1983, plaintiffs Samuel B. McCarter, First Seneca Bank & Trust Co., as executor for Dr. Leo Levine, and Olive M. Heck commenced an action by praecipe for writ of summons in the Court of Common Pleas of Warren County (Penn[198]*198sylvania) against defendants Merle M. Mitcham, Butcher & Singer, Inc., who were their stockbrokers, and Thomas Gabreski, who was a stock purchaser. The action was intended to recover losses from an alleged scheme to defraud in a stock deal in which plaintiffs claim to have been induced to sell securities at a price below fair market value. On August 16, 1984, approximately nine months following the filing of their state court action, the prothonotary sent notice to the plaintiffs pursuant to local (Warren County) Rule L 307, informing them that their suit would be dismissed for a failure to prosecute if it was not placed on the trial list within 240 days after commencement of the suit.1 The court subsequently ordered submission of a complaint by December 16, 1984, and discovery to be completed by January 15, 1985.
On January 21, 1985, after no complaint was filed by the date set by the court, defendants moved to dismiss for failure to file the complaint. On January 25, 1985, ten days after the discovery deadline, plaintiffs moved for an extension of time on the ground that their attorney was seriously ill. On April 25, 1985, plaintiffs filed a complaint, asserting claims under the Pennsylvania Securities Act of 1972, Pa. Stat.Ann. tit. 70, §§ 1-101 to 1-704 (Purdon Supp.1988), and state common law. See App. at 66-90.
On June 6, 1985, defendants filed preliminary objections alleging that the complaint was not timely filed. On September 24, 1985, the Court of Common Pleas ruled that the plaintiffs’ attorney’s illness was insufficient to justify the delay in filing the complaint and dismissed the action with prejudice. No. A.D. 540 of 1983 (C.P. Warren Sept. 24,1985). On December 15, 1986, the Superior Court of Pennsylvania affirmed. McCarter v. Mitcham, 362 Pa.Super. 644, 520 A.2d 1220 (1986).
On February 17, 1987, plaintiffs filed a complaint in the district court for the Western District of Pennsylvania asserting essentially identical claims, but pleading them as claims arising under the Racketeer Influenced and Corrupt Organizations Act, 18 U.S.C. §§ 1961-1968 (1982); section 10(b) of the Securities Exchange Act of 1934, 15 U.S.C. § 78j(b) (1982) (as well as claims under Rule 10b-5(a); 17 C.F.R. § 240.10b-5 (1988)); and state law (as pendent claims). See App. at 4-26. On March 12,1987, defendants moved to dismiss, Fed. R.Civ.P. 12(b)(6), and/or for summary judgment, Fed.R.Civ.P. 56, asserting that all of plaintiffs’ claims were barred by res judica-ta, that the section 10(b) claims were barred by the statute of limitations, and that the civil RICO claim failed to state a claim for relief. On May 6, 1987, the district court granted defendants’ motion to dismiss on the grounds that all of the claims were barred by res judicata and that the section 10(b) claims had not been filed within the applicable statute of limitations. See McCarter v. Mitcham, 693 F.Supp. 349, 350 (W.D.Pa.1987).
On May 15, 1987, plaintiffs moved for reconsideration. On July, 9, 1987, the district court stayed its action pending resolution of the appeal of the state court action by the Pennsylvania Supreme Court, but vacated the stay on April 22, 1988, after that court dismissed the appeal as improvidently granted. McCarter v. Mitcham, 517 Pa. 486, 538 A.2d 1335 (1988). On August 31, 1988, the district court denied the motion for reconsideration and reaffirmed its prior decision to dismiss, holding that the section 10(b) claims were time-barred and that all other' claims were barred by Pennsylvania res judicata law. 693 F.Supp. at 351-53. Appellants appeal this ruling.2
[199]*199II. RES JUDICATA
A. Pennsylvania Claim Preclusion Law
Under 28 U.S.C. § 1738 (1982), a state court’s judgment must be given the same effect in federal court that it would have been given in state court. Marrese v. American Academy of Orthopaedic Surgeons, 470 U.S. 373, 105 S.Ct. 1327, 84 L.Ed.2d 274 (1985); Kremer v. Chemical Construction Co., 456 U.S. 461, 102 S.Ct. 1883, 72 L.Ed.2d 262 (1982); Nanavati v. Burdette Tomlin Memorial Hospital, 857 F.2d 96 (3d Cir.1988), cert. denied, — U.S. —, 109 S.Ct. 1528, 103 L.Ed.2d 834 (1989). The Pennsylvania law of res judica-ta applies a four-part test to determine whether a claim is barred:
The application of res judicata requires a concurrence of four (4) conditions: (1) an identity of the thing sued upon; (2) an identity of the cause of action; (3) an identity of the persons and parties to the action; and (4) an identity of the quality or capacity of the parties suing or sued.
Dunham v. Temple University, 288 Pa.Super. 522, 534, 432 A.2d 993, 999 (1981).
For relitigation to be precluded, Pennsylvania law requires that the prior determination be “on the merits.” See Ross v. Bowlby, 353 Pa.Super. 59, 509 A.2d 332 (1986) (disposition of case not on the merits does not bar relitigation); Consolidation Coal Co. v. Dish 5, UMW, 336 Pa.Super. 354, 485 A.2d 1118 (1984) (res judicata applies where prior action was decided on the merits). Where the prior dismissal was based on a judgment of non pros, Pennsylvania courts will not give preclusive effect to the judgment. As the Pennsylvania Superior Court has stated:
[t]he legal effect of the entry of a judgment of non pros is not such as to preclude a plaintiff who suffers such a judgment from instituting another suit on the same cause of action provided, however, that the second suit is brought within the period of the statute of limitations [and the plaintiff is willing to pay for costs of the former suit].
Haefner v. Sprague, 343 Pa.Super. 342, 347, 494 A.2d 1115, 1118 (1985).3
Although neither the Superior Court nor the Supreme Court of Pennsylvania have spoken to the issue, Pennsylvania claim preclusion law also appears to require that the original court have subject matter jurisdiction over the cause of action in order for a claim based on that cause of action to be later barred in a second lawsuit in a court with subject matter jurisdiction over the cause of action. Pennsylvania lower courts have so held. See, e.g., Philadelphia v. Stradford Arms, Inc., 1 Pa.Commw. 190, 274 A.2d 277 (1971) (claim preclusion will only apply when first tribunal has equivalent subject matter jurisdiction as second). Furthermore, courts of other states have nearly universally required subject matter jurisdiction in the first action as a prerequisite to barring the second action. See Nanavati, 857 F,2d at 111.
B. Was the State Court Dismissal on the Merits?
The first major issue in this case is whether the state court dismissal with prejudice was a decision “on the merits” as that term is applied in Pennsylvania jurisprudence or whether instead it is analogous to a dismissal for failure to prosecute. As discussed above, an entry of judgment of non pros pursuant to the local rules for mere inactivity for an extended period of time would not bar relitigation under Pennsylvania preclusion law.
Applying Pennsylvania law, this Court has drawn a distinction between dismissal as a result of the simple failure to prose[200]*200cute and dismissal as a sanction for failure to obey a court order. Dismissals of the latter type most likely have preclusive effect. See Wade v. City of Pittsburgh, 765 F.2d 405, 408-09 (3d Cir.1985). This interpretation is suggested by the Superior Court in Dunham, which seems to say that, where a party fails to follow court orders and as a result its case is dismissed, res judicata applies even though there was no judicial decision finally addressing and adjudicating the merits of the case. See Dunham, 288 Pa.Super. at 533, 432 A.2d at 999. Moreover, the Superior Court in Consolidation Coal stated that where the prior action was dismissed with prejudice, further litigation may be barred even though there was, literally speaking, no decision “on the merits.” See Consolidation Coal, 336 Pa.Super. at 365, 485 A.2d at 1123. Thus, while no Pennsylvania court has squarely held that failure to follow a court order is a decision on the merits, it appears that the Pennsylvania courts interpret the phrase “on the merits” expansively, and would prohibit relitigation in some cases even when the original court has not actually entered a final decision on the merits of the case as such.
In this case, the state court, rather than permitting the prothonotary to dismiss the case automatically for failure to prosecute pursuant to Rule L 307, dismissed the case with prejudice following a failure by the plaintiffs to file the complaint within the extended time limits set by the court. The dismissal was not entered automatically by the prothonotary upon failure to file the complaint, but rather was issued by the court with a well-considered opinion and order dismissing the case with prejudice. The court stated in its opinion that “[djefen-dant’s motion is not for procedural non pro-sequitur.” Com.Pleas Op. at 5. We believe that, under these circumstances, the court’s dismissal was not for failure to prosecute, but rather as a sanction for the untoward delay in filing of the complaint.
We conclude therefore that the order to dismiss with prejudice was an order “on the merits” within the meaning set forth by the Pennsylvania courts. Hence, the prior litigation can be preclusive of any further litigation as long as the four prongs of the Pennsylvania res judicata inquiry are met and the Pennsylvania court had subject matter jurisdiction.
C. Are the Civil RICO Claims Barred by the Pennsylvania Law of Res Judica-ta?
As explained above, Pennsylvania courts would most likely not apply claim preclusion where the original court lacked subject matter jurisdiction. Plaintiffs argue that there is exclusive federal jurisdiction over civil RICO claims and therefore that their civil RICO claims cannot be barred. We conclude, however, that the civil RICO statute does not confer exclusive federal jurisdiction, but rather concurrent state and federal jurisdiction.
It is not clear whether, in the context of determining the state's law of preclusion, the jurisdictional reach of a federal statute is established by the state or federal court determination of the issue. Yet, we need not resolve this issue in this case, because we reach the same conclusion as that reached by the highest court of Pennsylvania to address the issue, Village at Camelback v. Carr, 371 Pa.Super. 452, 538 A.2d 528 (1988), app. granted, 519 Pa. 668, 548 A.2d 257 (1988): the civil RICO statute does not create exclusive federal jurisdiction.4
The courts of appeals are currently split on the question whether the civil RICO statute provides for exclusive federal jurisdiction. The Fourth and Ninth Circuits have held that there is concurrent jurisdiction. See Brandenburg v. Seidel, 859 F.2d 1179, 1193-95 (4th Cir.1988); Lou v. Belzberg, 834 F.2d 730, 738-39 (9th Cir.1987), cert. denied, — U.S. —, 108 S.Ct. 1302, 99 L.Ed.2d 512 (1988). The Fifth and [201]*201Seventh Circuits have expressed doubt that jurisdiction over civil RICO claims is exclusively federal. See Crotty v. City of Chicago Heights, 857 F.2d 1170, 1172 n. 6 (7th Cir.1988); DuBroff v. DuBroff, 838 F.2d 557, 562 (5th Cir.1987); County of Cook v. Midcon Corp., 773 F.2d 892, 905 n. 4 (7th Cir.1985). Only the Sixth Circuit has held that there is exclusive federal jurisdiction under civil RICO. See Chivas Products Ltd. v. Owen, 864 F.2d 1280, 1286 (6th Cir.1988). The Supreme Court has now granted certiorari to resolve this conflict. See Tafflin v. Levitt, 865 F.2d 595 (4th Cir.1989) (concurrent jurisdiction over civil RICO claims), cert. granted, — U.S. —, 109 S.Ct. 2428, 104 L.Ed.2d 985 (1989).
In view of the grant of certiorari, there would be nothing gained by an extensive discussion of this issue. Suffice it to say then that we are persuaded by Judge Kru-pansky’s dissent in Chivas as well as Judge Beck’s opinion in Village at Camelback and by those opinions of the courts of appeals that have determined that civil RICO jurisdiction is concurrent, Brandenburg and Belzberg. We hold therefore that there is not exclusive federal jurisdiction over civil RICO claims, but rather concurrent jurisdiction.
There can be no question that the four-part test, as set out in Dunham, supra at 199, for determining whether a claim is barred is met here with respect to the RICO claims. Between the federal complaint and the state complaint, there is a complete identity of the thing sued upon, the cause of action, the persons and parties to the action, and the quality or capacity of the parties suing or being sued. We conclude that the Pennsylvania courts would have had jurisdiction over the civil RICO claims and therefore that plaintiffs’ civil RICO claims are precluded by the Pennsylvania law of claim preclusion.5
D. Are the Securities Exchange Act of 1934 Claims Barred by the Pennsylvania Law of Res Judicata?
As explained above, the Pennsylvania law of res judicata would not bar relitigation where the state court did not have jurisdiction over the claim. Plaintiffs assert, and Mitcham does not argue to the contrary, that the section 10(b) and Rule 10b-5 Securities Exchange Act of 1934 claims are subject to exclusive federal jurisdiction.
Indeed, the Securities Exchange Act expressly provides for exclusive federal jurisdiction. See 15 U.S.C. § 78aa (1982 & West Supp.1989), and hence we must conclude that the Pennsylvania state courts would not have had jurisdiction over these claims. Thus, under Pennsylvania’s law of claim preclusion, the federal securities law claims are not barred. We must consider, therefore, whether the Securities Exchange Act of 1934 claims are barred by the statute of limitations.
III. STATUTE OF LIMITATIONS FOR THE SECURITIES EXCHANGE ACT OF 1934 CLAIMS
The sales of stock in question occurred between March 1981 and July 1981. There is no dispute that the claim accrued in 1981. The federal complaint was filed on February 17, 1987, over 5V2 years later. The district court held that the Securities Exchange Act of 1934 claims are barred by the applicable statute of limitations. We agree.
On April 8, 1988, we decided In re Data Access Systems Securities Litigation, 843 F.2d 1537 (3d Cir.1988) (in banc), holding [202]*202that the “the proper period of limitations for a complaint charging violation of Section 10(b) and Rule 10b-5 is one year after the plaintiff discovers the facts constituting the violation, and in no event more than three years after such violation.” Data Access, 843 F.2d at 1550. Data Access overruled our three prior cases on this point. See Sharp v. Coopers & Lybrand, 649 F.2d 175 (3d Cir.1981), cert. denied, 455 U.S. 938, 102 S.Ct. 1427, 71 L.Ed.2d 648 (1982); Biggans v. Bache Halsey Stuart Shields, Inc., 638 F.2d 605 (3d Cir.1980); Roberts v. Magnetic Metals Co., 611 F.2d 450 (3d Cir.1979). Under the prior overruled cases, plaintiffs’ federal complaint, which followed by 5% years the accrual of the action, was arguably filed in time. See A.J. Cunningham Packing v. Congress Financial Corp., 792 F.2d 330,332-37 (3d Cir.1986) (common law fraud claims accruing before February 1983 governed by six-year statute of limitations under Pennsylvania law). However, under Data Access, it was plainly filed out of time. We must decide whether Data Access is to be applied prospectively only. Data Access itself does not answer this question.
In general, an appellate court applies the law as it exists when the case is before it, i.e., retroactively, even though “that law may differ from the one in force ... at the time the events sparking the litigation occurred.” See Hill v. Equitable Trust Co., 851 F.2d 691, 695 (3d Cir.1988), cert. denied, — U.S. —, 109 S.Ct. 791, 102 L.Ed.2d 782 (1989). The Supreme Court has set out three criteria by which to decide whether a newly adopted rule should be applied prospectively only:
(1) The holding must establish a new principle of law, either by overruling clear past precedent on which litigants may have relied, or by deciding an issue of first impression whose resolution was not clearly foreshadowed;
(2) The merits and demerits in each case must be weighed by looking to the history of the rule in dispute, its purpose and effect, and whether retrospective operation will further or retard the rule’s operation;
(3)Retrospective application must create the risk of producing substantially inequitable results.
Hill, 851 F.2d at 696 (paraphrasing Chevron Oil Co. v. Huson, 404 U.S. 97, 106-07, 92 S.Ct. 349, 355-56, 30 L.Ed.2d 296 (1971)). The district court determined that these criteria were not met and therefore applied the shorter, Data Access, statute of limitations, holding that the federal securities claims were barred by the statute of limitations. In order to apply these criteria, we must summarize the prior precedent and the parties’ contentions with respect thereto.
A. The Prior Precedent
Before April 8, 1988, the statute of limitations for Rule 10b-5 cases in this Court was determined by borrowing the statute of limitations from the most analogous state cause of action. Plaintiffs argue that the most analogous referent is not the Pennsylvania securities law, but common law fraud, which is governed by a six-year statute of limitations. See A.J. Cunningham Packing, 792 F.2d at 330 (common law fraud claims accruing before February 1983 governed by six-year statute of limitations under Pennsylvania law). They submit that the three overruled cases, see supra at 202, established that 10b-5 actions must be analogized to common law fraud and therefore that a six-year statute of limitations then applied.
Roberts addressed the issue of the applicable statute of limitations under New Jersey, not Pennsylvania, law, but it is instructive here in that it set out the protocols for addressing the problem of what statute of limitations to apply. In Roberts, the panel split over the appropriate approach to take in determining the applicable statute of limitations where a stockholder sued a corporation and others for alleged securities violations. Judge Gibbons, writing the opinion of the court, approached the issue by attempting to determine a “state policy of repose." 611 F.2d at 456. Judge Sloviter, concurring on the issue of what approach should be taken to the problem, stated that “the selection of the one most appropriate to use must be made by consid[203]*203erations which comport with federal policy. The state policy of repose is relevant only if, and to the extent to which, it is consistent with the underlying federal claim.” Id. at 458. Judge Seitz, dissenting on the result, agreed in principle with Judge Slovi-ter’s approach. Id. at 460. The majority held that because the New Jersey securities act did not provide for a cause of action by anyone other than a buyer of securities, New Jersey’s common law remedies for breach of fiduciary duty and fraud applied. See id. at 453-54.
In Biggans, Judge Sloviter expressly recognized that her approach differed from that of Judge Gibbons in Roberts, but assumed that the same result would be attained in Biggans regardless of which approach was implemented. 638 F.2d at 608. In Biggans, this Court held that where the defendant was a broker and engaged in churning, the limitations period under the Pennsylvania law of securities was inapplicable because that statute only provides for causes of action against buyers and sellers. 638 F.2d at 610. Thus, the limitations period under the common law of fraud was analogous. In Sharp, we did not address the proper approach to take, but summarily followed Biggans and held that the Pennsylvania law of securities did not provide for causes of action except between buyers and sellers and therefore the cause of action in that case against an accounting firm was governed by the common law of fraud. 649 F.2d at 191-92.
B. Was There Clear Past Precedent?
Plaintiffs argue that there was clear precedent as to the statute of limitation to be applied. At the earliest time the plaintiffs could have discovered the fraud in this case, Roberts, Biggans, and Sharp had been decided. Plaintiffs argue that those cases stand for the proposition that “[i]f the underlying state [securities] law does not afford a civil damage action to remedy the behavior challenged by the 10b-5 claim and the plaintiff would be relegated to a common law fraud action for state relief, the courts must apply the fraud limitations provision to the 10b-5 action.” Hill v. Der, 521 F.Supp. 1370, 1383 (D.Del.1981). While this broad statement of the law may be correct, it does not answer the particular question before us in this case — whether there is clear past precedent. Upon scrutiny, we do not find that the applicable precedent would clearly render the common law fraud limitation period applicable to the facts of this case.
In Hill v. Equitable Trust, supra, we held that Data Access should be applied retroactively because there was not clear precedent on which plaintiffs could have relied in delaying the bringing of a Rule 10b-5 suit. Hill, 851 F.2d at 697. The court concluded that, as of the time of the filing of the complaint in that case, September 17, 1981, “the law in the circuit on this issue was in ferment” and that the extant decisions were essentially fact-based, making it difficult to predict what limitations period would apply to a particular case. Id. Similarly, the court in Data Access stated in 1988 that “[o]ur present case law calls for difficult interpretations of state limitation periods” requiring examination of each contention of a federal securities claim with “great particularity” and noted that district courts have found Third Circuit precedent to be of limited guidance. 843 F.2d at 1541. Generally speaking, then, the law with respect to 10b-5 was unsettled as late as 1988.
However, we must decide more particularly whether the facts of this ease have been clearly decided in prior cases. In this case, we have plaintiff-sellers, who were allegedly defrauded through the sale of securities to defendant-buyers through a defendant-broker. Thus, we must determine whether there was clear past precedent with respect to the applicable statute of limitations period for cases brought against buyers and brokers.
In Biggans and Sharp, this Court, interpreting Pennsylvania state law, held, respectively, that the Pennsylvania Securities Act does not apply to brokers involved in churning or to accounting firms that had prepared opinion letters regarding the securities. Although we stated in dicta that the Pennsylvania Securities Act provides a cause of action only against buyers and [204]*204sellers, we did not address in those cases the scope of the application of the Pennsylvania Securities Act to dealings between buyers and sellers. Neither did we consider whether brokers in the role of aiders and abettors would be liable under the Act. Thus, no case in the Third Circuit provided clear past precedent for the facts of this case.
Moreover, in 1982 the Superior Court of Pennsylvania called into question the assumption in Biggans (1980) and Sharp (1981) that the Pennsylvania Securities Act only provides causes of action against buyers and sellers, see Brennan v. Reed, Smith, Shaw & McClay, 304 Pa.Super. 399, 450 A.2d 740 (1982), making the relevant precedent even less clear. In Brennan, the court was faced, inter alia, with the question whether a law firm could be jointly and severally liable under the Pennsylvania Securities Act. The court concluded that the law firm could be held liable under section 503 of the act, stating that an attorney “can be held liable to an investor as a violator of the Securities Act.” Id. 450 A.2d at 747.
Although Brennan was not addressed in Hill v. Equitable Trust, it can be squared with the prior cases, because those cases suggested that section 501 of the Pennsylvania Securities Act of 1972, Pa.Stat.Ann. tit. 70, § 1-501, only provides a cause of action to buyers and sellers, but they did not consider whether a cause of action under the Act could be obtained under section 503. Pa.Stat.Ann. tit. 70, § 1-503; see Bull v. American Bank and Trust Co., 641 F.Supp. 62, 66 n. 5 (E.D.Pa.1986) (“Neither [Biggans nor Sharp ] discusses the scope of civil liability stemming from the interrelationship of §§ 501 and 503.”). Thus, even though the prior cases provided a general approach to the issue of what statute of limitations to apply (although even that is in some dispute, see supra at 203), they do not provide clear past precedent on which McCarter could have reasonably relied in delaying the filing of a claim under the federal securities laws. This is true with respect to the law as it existed at the time of the accrual of the claim in 1981 and it is also true with respect to the time of the filing of the federal suit on February 17, 1987.
Reliance on clear past precedent would militate in favor of the longer six-year statute of limitations. Because there was no clear past precedent upon which appellants could have reasonably relied in deciding when to file suit, this Chevron prong favors application of the shorter Data Access limitations period.
C. Would Retroactive Application Retard or Further the Rule’s Operation?
We next address the second Chevron criterion, which takes into account the history, purpose and effect of the rule in dispute in determining whether retroactive application will further or retard the rule’s operation. The district court concluded that this criterion was neutral, following the Hill v. Equitable Trust determination that the second criterion was neutral in that case. See 693 F.Supp. at 352.
We stated in Data Access that the factual, claim-based approach taken in the prior cases would not promote the strong federal interest in “uniformity, certainty, and the minimization of unnecessary litigation.” 843 F.2d at 1543 (quoting Wilson v. Garcia, 471 U.S. 261, 275, 105 S.Ct. 1938, 1946, 85 L.Ed.2d 254 (1985)). Thus, the purpose of the rule as announced in Data Access was to further uniformity and certainty. Permitting the least number of exceptions to the general rule of retroactivity would, of course, create more uniformity and certainty than would obtain under application of the prior Third Circuit precedent. Therefore, the second criterion might counsel retroactive application of the rule. However, this reasoning swallows the rule; under its regime, whenever a new statute of limitations is set, it would never properly be applied retroactively. We conclude that the second criterion does not “militate clearly either in favor of or against retroactive application” and is therefore neutral. Al-Khazraji v. Saint Francis College, 784 F.2d 505, 513 (3d Cir.1986), aff'd, 481 U.S. 604, 107 S.Ct. 2022, 95 L.Ed.2d 582 (1986).
[205]*205D. Would Retroactive Application Create the Risk of Substantially Inequitable Results?
We agree with the district court that there would be no inequity in applying the Data Access statute of limitations retroactively, because the federal complaint also would have been out of time under analogous state law. 693 F.Supp. at 352. If we were not to apply Data Access, we would have to identify the most analogous state law.
Although the issue has not been squarely decided in Pennsylvania, it would appear that the most analogous state law cause of action to plaintiffs’ section 10(b) claim against the defendant broker (Mitcham) and brokerage firm (Butcher and Singer), for deceptively inducing plaintiffs to sell the securities in question would be the Pennsylvania Securities Act, which prohibits brokers from inducing the sale or purchase of any security by means of deception, Pa.Stat.Ann. tit. 70, § 1-403, and which apparently provides for an action by an investor against a broker in section 503, Pa.Stat.Ann. tit. 70, § 1-503. See Bull v. American Bank, 641 F.Supp. at 65-67 & n. 5; Brennan, 304 Pa.Super. at 409, 450 A.2d at 745. The most analogous claim to the plaintiffs’ claim against defendant Ga-breski, one of the buyers of the securities, appears to be a claim under section 501(b) of the Pennsylvania Securities Act, which provides a cause of action against those who buy securities “by means of any untrue statement ... or any omission to state a material fact.” Pa.Stat.Ann. tit. 70, § l-501(b).
The limitations period under the Pennsylvania Securities Act is four years from the date of violation or one year after notice, whichever is earlier. Pa.Stat.Ann. tit. 70, § l-504(a). The filing in federal court 5V2 years after the accrual of the action falls beyond that limitation period. Thus, plaintiffs’ claims would be barred even if the holding in Data Access were not applied retroactively. Hence, retroactive application of the rule would not be inequitable.
E. Summary
We conclude that the first and third Chevron criteria counsel in favor of retroactive application of Data Access and that the second criterion is neutral, and therefore the shorter one-year or three-year statute of limitations under Data Access governs this case. Thus, the claims, filed 5V2 years after accrual of the action, were filed out of time.
IV. CONCLUSION
We hold that plaintiffs’ civil RICO and state claims are barred by res judicata. We also hold that plaintiffs’ federal securities law claims are barred by the statute of limitations. For these reasons, the order of the district court dismissing the plaintiffs’ complaint will be affirmed.
