OPINION OF THE COURT
The question on appeal is whether a claim may be maintained for violation of *509 the Pennsylvania Securities Act notwithstanding an agreement to submit such claims to arbitration. The district court refused to submit to arbitration a claim of violation of the Pennsylvania Securities Act because it construed a provision of that Act as forbidding judicial enforcement of prior agreements to arbitrate such claims. We conclude that recent Supreme Court precedent applying the Federal Arbitration Act requires a different result.
I.
Background
Plaintiff Milton Osterneck maintained an investment account with Merrill Lynch, Pierce, Fenner & Smith, Inc., with William Lampe as his broker. It is undisputed that in 1981 Osterneck signed a customer agreement that included a clause binding the parties to submit “any controversy between us arising out of your [Osterneck’s] business or this agreement” to arbitration. App. at 31. 1
Osterneck alleged in his complaint, inter alia, that Lampe fraudulently induced him to invest in an oil and gas leasing and development concern, and that Merrill Lynch either conspired with Lampe or negligently failed to prevent Lampe’s deception. This conduct, according to Osterneck, gave rise to violations of the federal Securities Exchange Act of 1934, the Pennsylvania Securities Act of 1972 and the state common law.
The district court stayed proceedings in Osterneck’s suit pending this court’s decision in another action on the issue of the arbitrability of claims under the federal Securities Exchange Act of 1934.

After the Supreme Court decided that claims under Section 10(b) of the Securities Exchange Act must be submitted to arbitration under the Federal Arbitration Act if the parties have so contracted,
Shearson/American Express, Inc. v. McMahon,
— U.S. —,
This court's precedent is clear that a district court order granting or denying a stay of its own proceedings pending arbitration is an appealable interlocutory order under 28 U.S.C. § 1292(a)(1) (1982), if the underlying action is at law rather than equity.

Discussion
The Pennsylvania Securities Act of 1972, 70 Pa.Stat.Ann. §§ 1-101 to 1-704 (Purdon Supp.1987), which is based on the Uniform Securities Act, 7B U.L.A. 515 (1985), is a comprehensive scheme regulating the securities industry. Section 507 of the Pennsylvania Securities Act, which is identical to section 410(g) of the Uniform Act, provides that “[a]ny condition, stipulation or provision binding any person acquiring any security to waive compliance with any provision of this act or any rule or order hereunder is void.” 70 Pa.Stat.Ann. § 1-507 (Pur-don Supp.1987).
In
Martin v. ITM/International Trading & Marketing,
The district court in this case relied on Martin to hold that the trial of Ostemeck’s Pennsylvania Securities Act claim need not be stayed pending arbitration. Neither party argues that either the district court or Martin erroneously construed the Pennsylvania statute as precluding enforcement of prior agreements to arbitrate. Instead, the parties have limited their arguments to Merrill Lynch’s contention that, so construed, section 507 conflicts with the Federal Arbitration Act and is therefore preempted.
Section 2 of the Federal Arbitration Act, 9 U.S.C. § 2 (1982), states that a “written provision in any ... contract evidencing a transaction involving commerce to settle by arbitration a controversy thereafter arising out of such contract or transaction ... shall be valid, irrevocable, and enforceable, save upon such grounds as exist at law or in equity for the revocation of any contract.” The Federal Arbitration Act further requires any “court[] of the United States” hearing a suit on such a contract to stay the action on application of one of the parties “until such arbitration has been had in accordance with the terms of the agreement.”
Id.
§ 3. Enacted in 1924, the Federal Arbitration Act carried out Congress’ intention to abolish the common law rale against judicial enforcement of arbitration agreements.
See Cost Brothers,
Congress derived its authority to enact the substantive rules of the Federal Arbitration Act from the Commerce Clause. The only limitations under the Federal Arbitration Act on the enforceability of a prior agreement to arbitrate are those stated in section 2 itself: the agreement must be part of a contract “evidencing a transaction involving commerce” which must not be otherwise revocable “upon such grounds as exist at law or in equity.”
See Southland Corp. v. Keating,
The preemptive force of the Federal Arbitration Act is clearly established. In
Southland,
the Court held that Congress, in creating the substantive rule of law enforcing arbitration agreements, “intended to foreclose state legislative attempts to undercut the enforceability of arbitration agreements.”
Ostemeck argues only that this court should enforce the provisions of the Pennsylvania Securities Act “[ujnder the principle of
Erie Railroad Co. v. Tompkins,
The decision of the district court in this case was grounded in the view, expressed by the Supreme Court in
Wilko v. Swan,
Whatever the continued vitality of
Wil-ko,
subsequent Court decisions have limited its application to the precise issue before the Court there. In
Wilko,
decided in 1953, the Court opined that arbitration was more suited to solving commercial controversies than to protecting the rights of investors.
Id.
at 438,
In cases decided after
Wilko,
the Court has consistently enforced the Federal Arbitration Act’s broad mandate for arbitration notwithstanding the strong legislative policy underlying the grant of a private cause of action to enforce rights granted under a particular statute. In a case upholding the application of an arbitration clause to a federal antitrust claim, the Court observed that “we are well past the time when judicial suspicion of the desirability of arbitration and of the competence of arbitral tribunals inhibited the development of arbitration as an alternative means of dispute resolution.”

Moreover, even in cases involving securities claims, the Court upheld the requirement of arbitration. In
Scherk v. Alberto-Culver Co.,
Dean Witter Reynolds Inc. v. Byrd,
Finally, in
McMahon,
the Court resolved a conflict in the circuits and made its position unambiguous by reversing the Second Circuit’s decision that
Wilko
precluded arbitration of claims under the 1934 Securities Exchange Act.
The conclusion in Wilko was expressly based on the Court’s belief that a judicial forum was needed to protect the substantive rights created by the Securities Act: “As the protective provisions of the Securities Act require the exercise of judicial direction to fairly assure their effectiveness, it seems to us that Congress must have intended § 14 ... to apply to waiver of judicial trial and review.” [Wilko, 346 U.S.] at 437 [74 S.Ct. at 188 ]. Wilko must be understood, therefore, as holding that the plaintiff’s waiver of the “right to select the judicial forum,” id., at 435 [74 S.Ct. at 186 ], was unenforceable only because arbitration was judged inadequate to enforce the statutory rights created by § 12(2).
As long as
Wilko
stands in the Supreme Court, agreements to arbitrate claims under the Securities Act of 1933 will remain unenforceable, but that is the only rule
Wilko
now stands for. The overwhelming weight of precedent militates against following
Wilko
to a finding that Congress intended to exempt state securities claims from the general command of the Federal Arbitration Act. Although we are mindful. of the threshold presumption that Congress did not intend to displace state law,
see Cipollone v. Liggett Group, Inc.,
III.
Conclusion
For the reasons set forth above, we will reverse the district court’s order denying defendant’s motion to compel arbitration of Ostemeck’s claims arising under the Pennsylvania Securities Act. We will remand the case to the district court with instructions to direct arbitration of these claims.
