This case raises questions relating to the power of a federal district judge to stay a federal suit involving questions of federal law which have already been decided in a parallel state suit
1
when he determines that the federal suit has been brought to delay the state proceeding. Such a deferral to a
*1230
state court for reasons of “wise judicial administration” not falling within the ambit of the abstention doctrine was first recognized by the Supreme Court in
Colorado River Water Conservation District v. United States,
American Mutual Reinsurance Company (Amreco) solicited Calvert Fire Insurance Company’s (Calvert) participation in its reinsurance pool, composed of 99 other insurance companies which shared the profits and losses of the pool. In early 1974, Calvert agree to participate for the year 1974. In April of that year, two events of significance occurred. First, Amreco issued financial information relating to the pool’s performance in 1973; and, second, a wave of tornadoes struck the Midwest, assuring that the pool would suffer losses for the year 1974. Under the terms of the participation agreement, Calvert would become liable for its share of the 1974 losses. By telegram of April 19, 1974, Calvert requested that Am-reco terminate its membership in the pool, retroactive to January 1, 1974. In a followup letter, Calvert explained that it would never have joined the pool had it been informed, prior to signing the participation agreement, of the extent of the pool’s losses in 1973. 3
On July 7, 1974, Amreco filed a suit in state court to obtain a declaration that the participation agreement was still in full force and effect. Calvert defended at first on the ground that a declaratory action was not an appropriate remedy for breach of contract, and then on the ground that the action should be transferred from the Law Division to the Equity Division. Unsuccessful in both these arguments, Calvert sought certification of these issues for interlocutory appeal and stay of discovery pending their final resolution. Certification was denied.
On January 15, 1975, a full six months after the filing of Amreco’s declaratory judgment action, Calvert first raised the affirmative defense that it was misled by Amreco during the negotiations leading to the signing of the participation agreement and, accordingly, was entitled to rescission of the agreement. In support of this new argument, it cited the state common law of fraud and also the anti-fraud provisions of state and federal securities acts. 4 Securities law was invoked on the theory that a participatory interest in a reinsurance pool constitutes a “security” which was “sold” to Calvert within the meaning of the securities acts. Calvert also filed a counterclaim for two million dollars in damages on all the same legal theories asserted in its defense, *1231 with the conspicuous exception of the 1934 Securities Exchange Act.
On the same day it filed its state defense and counterclaim on the above fraud theories, Calvert filed a federal suit for rescission and two million dollars in damages on all the same legal theories, with the addition of the 1934 Act, which it had not pled in its state counterclaim for damages.
On May 6,1975, Judge Hubert Will of the Northern District of Illinois, to whom the federal suit had been assigned, entered an unpublished order and memorandum opinion staying all aspects of Calvert’s federal suit concurrently before the state court. The stay extended to all the theories cited by Calvert in state court, including the 1934 Act claim for rescission, since we have interpreted Section 27 of the 1934 Act
5
to allow concurrent jurisdiction in the state courts of 1934 Act defenses to a state cause of action.
Aetna State Bank v. Altheimer,
On May 9, 1975, Judge Will, who had invited the Judge in the state action to sit with him, heard oral argument on the question of whether a participatory interest in a reinsurance pool constituted a “security” under the definition of that term in the 1933 and 1934 Acts. On June 16, 1975, the state judge 7 handed down an order deciding that question in the negative. At that point, and not before, Judge Will apparently decided informally on his own motion to postpone decision on the federal security question.
Calvert applied to this court for a writ of mandamus seeking (1) a reversal of Judge Will’s order of May 6, 1975 to the extent it stayed Calvert’s 1934 Act claim for rescission and (2) an order compelling Judge Will to rule immediately on the 1934 Act claim for damages. We granted the writ, not finding the “exceptional circumstances” which, under
Colorado River, supra,
would allow federal court deferral to a parallel state court proceeding for reasons of “wise judicial administration.” As we thought that Judge Will’s decision to stay had been correct under our
pre-Colorado River
decision in
Aetna State Bank v. Altheimer, supra,
we overruled that case.
Calvert Fire Ins. Co. v. Will,
The Supreme Court, in a 4-4-1 opinion, reversed our mandamus order. Justice Rehnquist, speaking for four of the five justices voting for reversal, addressed only the propriety of staying the 1934 Act rescission claim, which was concurrently before the state court. He held that mandamus
*1232
was appropriate only where there was a “clear and indisputable” right to the writ, which he could not find here since, in his view, district judges possess a discretionary power to stay a matter concurrently before a state court.
Will v. Calvert Fire Ins. Co.,
Justice Blackmun provided the swing vote for reversal on the limited ground that our grant of the writ of mandamus had been premature in light of the fact that Colorado River had not been decided at the time Judge Will made his original decision to stay, and that we should have done no more than remand to Judge Will for reconsideration of his decision in light of Colorado River.
On remand to this Court, we were faced with the task of interpreting the position of a majority of the Justices. We concluded that Judge Will should be afforded the opportunity of reevaluating his decision to stay in light of
Colorado River. Calvert Fire Insurance Co.
v.
Will,
In his subsequent decision, which is the one now under review, Judge Will made it clear that he had also deliberately stayed decision on the 1934 Act damage claim and that postponement of decision on that claim had not been due to the normal heavy workload of the court, as Justice Rehnquist had postulated. However, he explained his stay of the damage claim by pointing out that Calvert had admitted in oral argument before the Supreme Court that it had no claim for damages against Amreco since it had paid nothing into the pool and rescission would therefore make it whole.
8
Thus dismissing Calvert’s only claim to the exclusive jurisdiction of the federal courts, Judge Will concluded that continuing the stay of Calvert’s concurrent claims was justified since Calvert had already obtained an adjudication of all its federal securities claims from the state court and he could only conclude that its continuing quest for a federal readjudication of the same security issue was a delaying tactic.

Calvert Fire Insurance Co. v. American Mutual Reinsurance Co.,
Judge Will did not think that a stay postponing decision of a vexatious federal suit was inconsistent with
Colorado River
since that case recognized a discretionary power to dismiss federal question suits for reasons of wise judicial administration. Furthermore, even if the “exceptional circumstances” justifying a
Colorado River
-type dismissal were arguably not present here, there were several points distinguishing the present case from
Colorado River.
First, Judge Will had only
stayed
Calvert’s federal suit whereas the federal suit in
Colorado River
had been
dismissed
outright; and, second, Calvert had failed to utilize the removal procedure created by 28 U.S.C. § 1441, although available on the basis of diversity of citizenship.

*1233
Any discussion of federal court deferral to a parallel state proceeding for reasons apart from the three traditional categories of abstention
11
must begin with
Colorado River Water Conservation District v. United States,
There are, therefore, situations where a federal court may defer to a parallel state proceeding, even when the result will be to relegate decision of questions of federal law over which the district court has jurisdiction to a state forum. The reason for such deferral is to prevent duplication of judicial effort in two separate court systems and to confine the litigation to the forum able to make the most comprehensive disposition. Dismissal for reasons of “wise judicial administration,”
The Supreme Court made it clear that the circumstances justifying federal court deferral to a state proceeding are still considerably more limited than the circumstances permitting federal court deferral to another federal court.
In the present case, Judge Will would place much emphasis on his perception of the federal suit as a reactive defensive maneuver by Calvert to delay the state proceeding and postpone final resolution of its dispute with Amreco. 14 Certainly, under Colorado River, it was proper for Judge Will to consider the vexatious nature of the federal suit as well as any other factors bearing on the propriety of continuing the stay. Preventing a vexatious suit is similar to the interest in avoiding piecemeal litigation mentioned in Colorado River, supra at 818, and would clearly justify federal deferral to a parallel state proceeding unless there exist strong countervailing reasons for the federal court to decide the federal suit without further delay, such as prejudice to Calvert or compelling policy reasons to secure an immediate federal court decision on a 1934 Act issue concurrently within the jurisdiction of the state court.
In deciding the present case, it is important to bear in mind two factors persistently denied or played down by Calvert. First, this case is most definitely one involving the concurrent jurisdiction of the state and federal courts and, second, Judge Will has never purported to dismiss the federal suit. So long as Judge Will has not actually dismissed the federal suit and there remains a meaningful distinction between a stay and a dismissal, the issue before us remains confined to the narrow one of whether there are any policy considerations supporting an immediate, as opposed to eventual, ruling by Judge Will on the security question already decided by the state court.
*1235
The stay entered in this case is not equivalent to a dismissal because (1) Judge Will made the decision to stay the 1934 Act damage claim only after the state court had already ruled on the security question, see
We are not persuaded by such an argument. In the absence of a legitimate claim to exclusive federal jurisdiction, we see no reason why a federal court should not stay its hand pending termination of a parallel state proceeding, at least where the district judge has found the federal suit to be vexatious.
The interest in having a federal court decide the 1934 Act claim here involved is attenuated since Calvert has no claim for affirmative relief as did the federal plaintiff in
Lyons v. Westinghouse Electric Corp.,
*1236 600 FEDERAL REPORTER, 2d SERIES
Countering the weak interest in having a federal court decide a 1934 Act claim for rescission already decided by a state court in a proper exercise of its concurrent jurisdiction and the even weaker interest in obtaining such a decision prior to completion of all phases of the state suit (which is the only interest we need consider here), is the strong support in policy for furnishing district judges with a means to deter vexatious use of the federal courts. A limited power to stay a federal suit until termination of a parallel state suit represents a reasonable accommodation of the conflict between the needs of wise judicial administration and the obligation of the federal courts to exercise their jurisdiction.
See Mottolese v. Kaufman,
Such a stay continues to be justified even after the state court has decided all the federal issues within its concurrent jurisdiction because a decision on the state law issues favorable to the federal plaintiff may obviate the need for .a federal decision and, even if the federal plaintiff still desires to pursue his federal action after conclusion of the state suit, state court findings of fact on state causes of action paralleling the federal cause of action may be entitled to collateral estoppel effect in a subsequent federal suit.
See Klein v. Walston & Co., Inc.,
Accordingly, Judge Will’s continued stay of all proceedings in the federal suit pending termination of the state action is affirmed. After the state court decides Calvert’s common law fraud claim, Judge Will will have to decide whether to dismiss the suit outright or rule on the security question. If he chooses the latter course, he will first have to ascertain the proper weight to accord the prior state court decision under the res judicata doctrine. 18
AFFIRMED.
Notes
. A suit is “parallel” when substantially the same parties are contemporaneously litigating substantially the same issues in another forum, thus making it likely that judgment in one suit will have a res judicata effect in the other suit. Here the parties and issues are identical in the state and federal suits, although the posture of the parties is reversed, so that the defendant in the state suit has become the plaintiff in the federal suit.

. The state securities acts on which Calvert relied were the Maryland Securities Law and the Illinois Securities Act. Calvert is a Pennsylvania corporation with its principal office in .the state of Maryland, and Amreco is an Illinois corporation with its principal office in the state of Illinois.
The federal statutes cited by Calvert were the Securities Act of 1933 and the Securities Exchange Act of 1934. The 1933 Act vests concurrent jurisdiction in the state and federal courts, while the 1934 Act grants the federal district courts exclusive jurisdiction to enforce the Act. Calvert’s 1934 Act claims for rescission and damages are based on Rule 10b-5 promulgated under § 10(b) of the Act. 17 CFR § 240.1 Ob-5.
. Section 27 provides, in pertinent part:
The district courts of the United States shall have exclusive jurisdiction of violations of this title or the rules and regulations thereunder, and of all suits in equity and actions at law brought to enforce any liability or duty created by this title or the rules and regulations thereunder.
15 U.S.C. § 78aa.
. The status of
Aetna
as the law of this Circuit is unclear as it was overruled by an even division of the eight judges of this Court in regular active service in
Calvert Fire Ins. Co. v. Will,
. Hon. Arthur Dunne of the Circuit Court of Cook County, Illinois.
. The Supreme Court did not mention this admission by Calvert anywhere in its opinion, although its significance was acknowledged by Calvert, which dropped its prayer for damages as a basis for exclusive federal jurisdiction under the 1934 Act in its argument before this Court.
. As Judge Will pointed out, Calvert had a financial interest in delay, since the longer it could postpone a possible obligation to pay money into the pool, the longer it could benefit from the difference between the statutory interest rate and the prevailing commercial interest rate.
. Calvert explained its failure to remove the state suit to federal court on the ground that it did not think of its securities law cause of action until after the 30 day period for removal specified in 28 U.S.C. § 1446(b). It thus had no reason to remove the suit prior to that time, although the jurisdictional basis for removal (diversity) had been present from the start of the suit.
. Abstention is appropriate in the following situations:
(1) “ ‘in cases presenting a federal constitutional issue which might be mooted or presented in a different posture by a state court determination of pertinent state law’
(2) “where there have been presented difficult questions of state law bearing on policy problems of substantial public import whose importance transcends the result in the case then at bar”; and
(3) “where, absent bad faith, harassment, or a patently invalid state statute, federal jurisdiction has been invoked for the purpose of restraining state criminal proceedings.”
Colorado River,
. At issue were the water rights of certain federal lands. The United States asserted the water rights of national parks and forests on its own behalf and the water rights of certain Indian reservations on behalf of some Indian tribes.
. There was no particular state proceeding under way, but the Colorado Water Right Determination and Administration Act, Colo.Rev. Stat.Ann. § 37-92-101
et seq.
(1974), creates what amounts to a single continuous proceeding for water rights adjudication. See
. Judge Will’s characterization of the suit as vexatious is essentially a factual finding which we should accept on appeal unless contrary to the weight of the evidence. Such is not the case here. There was ample evidence to support his finding that Calvert sought to delay a final decision on its liability under the participation agreement, and also that it sought to employ the federal suit as part of its delaying strategy. While delay is a legitimate trial tactic, it is not one which the federal courts are required to go along with.
The evidence supporting Judge Will’s view of the federal suit includes the following:
(1) Calvert did not assert its affirmative defense of fraud until six months after Amreco brought suit for declaratory relief in state court, employing instead a combination of technical objections to the suit and requests for stay of discovery pending interlocutory appeal of these objections. See p. 1230 supra and Amreco Brief at 2.
(2) Calvert failed to utilize the removal statute, 28 U.S.C. § 1441, even though the diversity basis for removal existed at the initiation of the state suit.
(3) Calvert used the federal suit to stay discovery in the state suit. See459 F.Supp. at 864 and n. 5.
While none of the above acts standing alone would be particularly significant, their cumulative effect is to suggest that Calvert sought to delay a final decision and use the federal courts as part of this plan.
For a proposal that the stay power be used to prevent circumvention of the removal statute, see Note, Stays of Federal Proceedings in Deference to Concurrently Pending State Court Suits, 60 Col.L.Rev. 684, 704 (1960).
. In our earlier opinion on the mandamus issue we concluded that the stay was “equivalent to a dismissal for purposes of this case,”
It has been said that “[a] stay in deference to parallel proceedings will usually have the same effect as a dismissal because of the effects of res judicata.” Comment, Federal Court Stays and Dismissals in Deference to Parallel State Court Proceedings: The Impact of Colorado River, 44 U.Chi.L.Rev. 641, 662 n. 143 (1977). However, this ground for equating stays and dismissals cannot be said to apply here since Judge Will only decided to postpone decision on the security question after the possibility of res judicata had already arisen due to Judge Dunne’s prior ruling on that question.
Other decisions have distinguished between the two forms of disposition.
See Will v. Calvert,
. Although the present case does not involve a claim to the exclusive jurisdiction of the federal courts, it is interesting to note that both Professor Louis Loss and the American Law Institute *1236 have recommended that § 27 of the 1934 Act be amended to conform to the concurrent jurisdiction pattern of all the other SEC acts. II Loss, Securities Regulation 998 (2d ed. 1961) and Supp. to 2d edition, vol. VI, p. 4142. There was no legislative discussion of § 27 prior to its enactment.
. Professors David Currie and Philip Kurland have suggested that the Judicial Code be amended to provide for stays of federal suits if there is a prior state or federal suit pending.
See
Currie, The Federal Courts and the American Law Institute (pt. II), 36 U.Chi.L.Rev. 268, 335 (1969); Kurland, Toward a Cooperative Judicial Federalism: The Federal Court Abstention Doctrine,
. The res judicata effect of a prior state court decision on a pure question of law involving interpretation of a federal statute (such as Judge Dunne’s decision that a participatory interest in a reinsurance pool does not constitute a “security”) is an unsettled question.
See MacGregor v. Westinghouse Elec. & Mfg. Co.,
It appears fairly settled, however, that state court findings of
fact
are entitled to collateral estoppel effect in a subsequent federal suit, even if dispositive of the federal question.
See Becher v. Contoure Laboratories, Inc.,
Mixed questions of law and fact lie somewhere in the middle. For a criticism of according such importance to characterization of an issue as factual or legal, see 8 Stan.L.Rev. 439, supra at 443^446.
