delivered the opinion of the Court.
Section 16 (b) of the Securities Exchange Act of 1934, 48 Stat. 896, 15 U. S. C. § 78p (b),1 provides that officers, *584directors, and holders of more than 10% of the listed stock of any company shall be liable to the company for any profits realized from any purchase and sale or sale and purchase of such stock occurring within a period of six months. Unquestionably, one or more statutory purchases occur when one company, seeking to gain control of another, acquires more than 10% of the stock of the latter through a tender offer made to its shareholders. But is it a § 16 (b) “sale” when the target of the tender offer defends itself by merging into a third company and the tender offeror then exchanges his stock for the stock of the surviving company and also grants an option to purchase the latter stock that is not exercisable within the statutory six-month period? This is the question before us in this case.
I
On May 8, 1967, after unsuccessfully seeking to merge with Kern County Land Co. (Old Kern),2 Occidental Petroleum Corp. (Occidental) 3 announced an offer, to expire on June- 8, 1967, to purchase on a first-come, first-served basis 500,000 shares of Old Kern common stock 4 at a price of $83.50 per share plus a broker*585age commission of $1.50 per share.5 By May 10, 1967, 500.000 shares, more than 10% of the outstanding shares of Old Kern,6 had been tendered. On May 11, Occidental extended its offer to encompass an additional 500.000 shares. At the close of the tender offer, on June 8, 1967, Occidental owned 887,549 shares of Old Kern.7
Immediately upon the announcement of Occidental’s tender offer, the Old Kern management undertook to frustrate Occidental’s takeover attempt. A management letter to all stockholders cautioned against tender and indicated that Occidental’s offer might not be the best available, since the management was engaged in merger discussions with several companies. When Occidental extended its tender offer, the president of Old Kern sent a telegram to all stockholders again advising against tender. In addition, Old Kern undertook merger dis*586cussions with Tenneco, Inc. (Tenneco),8 and, on May 19, 1967, the Board of Directors of Old Kern announced that it had approved a merger proposal advanced by Tenneco.9 Under the terms of the merger, Tenneco would acquire the assets, property, and goodwill of Old Kern, subject to its liabilities, through “Kern County Land Co.” (New Kern),10 a new corporation to be formed by Tenneco to receive the assets and carry on the business of Old Kern. The shareholders of Old Kern would receive a share of Tenneco cumulative convertible preference stock in exchange for each share of Old Kern common stock which they owned. On the same day, May 19, Occidental, in a quarterly report to stockholders, appraised the value of the new Tenneco stock at $105 per share.11
*587Occidental, seeing its tender offer and takeover attempt being blocked by the Old Kern-Tenneco “defensive” merger, countered on May 25 and 31 with two mandamus actions in the California courts seeking to obtain extensive inspection of Old Kern books and records.12 Realizing that, if the Old Kern-Tenneco merger were approved and successfully closed, Occidental would have to exchange its Old Kern shares for Tenneco stock and would be locked into a minority position in Tenneco, Occidental took other steps to protect itself. Between May 30 and June 2, it negotiated an arrangement with Tenneco whereby Occidental granted Tenneco Corp., a subsidiary of Tenneco, an option to purchase at $105 per share all of the Tenneco preference stock to which Occidental would be entitled in exchange for its Old Kern stock when and if the Old Kern-Tenneco merger was closed.13 The premium to secure the option, at $10 per share, totaled $8,866,230 and was to be paid immediately upon the signing of the option agreement.14 If the option were exercised, the premium was to be applied to the purchase price. By the terms of the option agreement, the option could not be exercised prior to Decem*588ber 9,1967, a date six months and one day after expiration of Occidental’s tender offer. On June 2, 1967, within six months of the acquisition by Occidental of more than 10% ownership of Old Kern, Occidental and Tenneco Corp. executed the option.15 Soon thereafter, Occidental announced that it would not oppose the Old KernTenneco merger and dismissed its state court suits against Old Kern.16
The Old Kern-Tenneco merger plan was presented to and approved by Old Kern shareholders at their meeting on July 17, 1967. Occidental refrained from voting its Old Kern shares, but in a letter read at the meeting Occidental stated that it had determined prior to June 2 not to oppose the merger and that it did not consider the plan unfair or inequitable.17 Indeed, Occidental indicated that, had it been voting, it would have voted in favor of the merger.
Meanwhile, the Securities and Exchange Commission had refused Occidental’s request to exempt from possible § 16 (b) liability Occidental’s exchange of its Old Kern stock for the Tenneco preference shares that would take *589place when and if the merger transaction were closed. Various Old Kern stockholders, with Occidental’s interests in mind, thereupon sought to delay consummation of the merger by instituting various lawsuits in the state and federal courts.18 These attempts were unsuccessful, however, and preparations for the merger neared completion with an Internal Revenue Service ruling that consummation of the plan would result in a tax-free exchange with no taxable gain or loss to Old Kern shareholders, and with the issuance of the necessary approval of the merger closing by the California Commissioner of Corporations.
The Old Kern-Tenneco merger transaction was closed on August 30. Old Kern shareholders thereupon became irrevocably entitled to receive Tenneco preference stock, share for share in exchange for their Old Kern stock. Old Kern was dissolved and all of its assets, including “all claims, demands, rights and choses in action accrued or to accrue under and by virtue of the Securities Exchange Act of 1934 . . . ,” were transferred to New Kern.
The option granted by Occidental on June 2, 1967, was exercised on December 11, 1967. Occidental, not having previously availed itself of its right, exchanged certificates representing 887,549 shares of Old Kern stock for a certificate representing a like number of shares of Tenneco preference stock. The certificate was then endorsed over to the optionee-purchaser, and in return $84,229,185 was credited to Occidental’s accounts at various banks. Adding to this amount the $8,886,230 premium paid in June, Occidental received $93,905,415 for its Old Kern stock (including the 1,900 shares acquired prior to issuance of its tender offer). In addition, Occidental received dividends totaling $1,793,439.22. Occidental’s *590total profit was $19,506,419.22 on the shares obtained through its tender offer.
On October 17, 1967, New Kern instituted a suit under § 16 (b) against Occidental to recover the profits which Occidental had realized as a result of its dealings in Old Kern stock. The complaint alleged that the execution of the Occidental-Tenneco option on June 2, 1967, and the exchange of Old Kern shares for shares of Tenneco to which Occidental became entitled pursuant to the merger closed on August 30, 1967, were both “sales” within the coverage of § 16 (b). Since both acts took place within six months of the date on which Occidental became the owner of more than 10% of the stock of Old Kern, New Kern asserted that § 16 (b) required surrender of the profits realized by Occidental.19 New Kern eventually moved for summary judgment, and, on December 27, 1970, the District Court granted summary judgment in favor of New Kern. Abrams v. Occidental Petroleum Corp., 323 F. Supp. 570 (SDNY 1970). The District Court held that the execution of the option on June 2, 1967, and the exchange of Old Kern shares for shares of Tenneco on August 30, 1967, were “sales” under § 16 (b). The Court ordered Occidental to disgorge its profits plus interest. In a supplemental opinion, Occidental was also ordered to refund the dividends which it had received plus interest.
On appeal, the Court of Appeals reversed and ordered summary judgment entered in favor of Occidental. Abrams v. Occidental Petroleum Corp., 450 F. 2d 157 (CA2 1971). The Court held that neither the option nor the exchange constituted a “sale” within the purview of *591§ 16 (b).20 We granted certiorari. 405 U. S. 1064 (1972). We affirm.

Section 16 (b) provides, inter alia, that a statutory insider 21 must surrender to the issuing corporation “any profit realized by him from any purchase and sale, or any sale and purchase, of any equity security22 of such issuer . . . within any period of less than six months.” As specified in its introductory clause, § 16 (b) was enacted “[f]or the purpose of preventing the unfair use of information which may have been obtained by [a statutory insider] ... by reason of his relationship to the issuer.” Congress recognized that short-swing speculation by stockholders with advance, inside information would threaten the goal of the Securities Exchange Act to “insure the maintenance of fair and honest markets.” *59215 U. S. C. § 78b. Insiders could exploit information not generally available to others to secure quick profits. As we have noted, “the only method Congress deemed effective to curb the evils of insider trading was a flat rule taking the profits out of a class of transactions in which the possibility of abuse was believed to be intolerably great.” Reliance Electric Co. v. Emerson Electric Co., 404 U. S. 418, 422 (1972). As stated in the report of the Senate Committee, the bill aimed at protecting the public “by preventing directors, officers, and principal stockholders of a corporation . . . from speculating in the stock on the basis of information not available to others.” S. Rep. No. 792, 73d Cong., 2d Sess., 9 (1934).23
*593Although traditional cash-for-stock transactions that result in a purchase and sale or a sale and purchase within the six-month, statutory period are clearly within the purview of § 16 (b), the courts have wrestled with the question of inclusion or exclusion of certain “unorthodox” transactions.24 The statutory definitions of “purchase” *594and “sale” are broad and, at least arguably, reach many transactions not ordinarily deemed a sale or purchase.25 In deciding whether borderline transactions are within the reach of the statute, the courts have come to inquire whether the transaction may serve as a vehicle for the evil which Congress sought to prevent — the realization of short-swing profits based upon access to inside information26 — thereby endeavoring to implement con*595gressional objectives without extending the reach of the statute beyond its intended limits. The statute requires the inside, short-swing trader to disgorge all profits realized on all “purchases” and “sales” within the specified time period, without proof of actual abuse of insider information, and without proof of intent to profit on the basis of such information. Under these strict terms, the prevailing view is to apply the statute only when its application would serve its goals. “[WJhere alternative constructions of the terms of § 16 (b) are possible, those terms are to be given the construction that best serves the congressional purpose of curbing short-swing speculation by corporate insiders.” Reliance Electric Co. v. Emerson Electric Co., 404 U. S., at 424. See Blau v. Lamb, 363 F. 2d 507 (CA2 1966), cert, denied, 385 U. S. 1002 (1967). Thus, “ [i] n interpreting the terms ‘purchase’ and ‘sale,’ courts have properly asked whether the particular type of transaction involved is one that gives rise to speculative abuse.” Reliance Electric Co. v. Emerson Electric Co., supra, at 424 n. 4.27
In the present case, it is undisputed that Occidental became a “beneficial owner” within the terms of § 16 (b) when, pursuant to its tender offer, it “purchased” more than 10% of the outstanding shares of Old Kern. We must decide, however, whether a “sale” within the ambit of the statute took place either when Occidental became irrevocably bound to exchange its shares of Old Kern for shares of Tenneco pursuant to the terms of the merger agreement between Old Kern and Tenneco or *596when Occidental gave an option to Tenneco to purchase from Occidental the Tenneco shares so acquired.28
III
On August 30, 1967, the Old Kern-Tenneco merger agreement was signed, and Occidental became irrevocably-entitled to exchange its shares of Old Kern stock for shares of Tenneco preference stock. Concededly, the transaction must be viewed as though Occidental had made the exchange on that day. But, even so, did the exchange involve a “sale” of Old Kern shares within the meaning of § 16 (b) ? We agree with the Court of Appeals that it did not, for we think it totally unrealistic to assume or infer from the facts before us that Occidental either had or was likely to have access to inside information, by reason of its ownership of more than 10% of the outstanding shares of Old Kern, so as to afford it an opportunity to reap.speculative, short-swing profits from its disposition within six months of its tender-offer purchases.
It cannot be contended that Occidental was an insider when, on May 8, 1967, it made an irrevocable offer to purchase 500,000 shares of Old Kern stock at a price substantially above market. At that time, it owned only 1,900 shares of Old Kern stock, far fewer than the 432,000 shares needed to constitute the 10% ownership required by the statute. There is no basis for find*597ing that, at the time the tender offer was commenced, Occidental enjoyed an insider’s opportunity to acquire information about Old Kern’s affairs.
It is also wide of the mark to assert that Occidental, as a sophisticated corporation knowledgeable in matters of corporate affairs and finance, knew that its tender offer would either succeed or would be met with a “defensive merger.” If its takeover efforts failed, it is argued, Occidental knew it could sell its stock to the target company’s merger partner at a substantial profit. Calculations of this sort, however, whether speculative or not and whether fair or unfair to other stockholders or to Old Kern, do not represent the kind of speculative abuse at which the statute is aimed, for they could not have been based on inside information obtained from substantial stockholdings that did not yet exist. Accepting both that Occidental made this very prediction and that it would recurringly be an accurate forecast in tender-offer situations,29 we nevertheless fail to perceive how the fruition of such anticipated events would require, or in any way depend upon, the receipt and use of inside information. If there are evils to be redressed by way of deterring those who would make tender offers, *598§ 16 (b) does not appear to us to have been designed for this task.
By May 10, 1967, Occidental had acquired more than 10% of the outstanding shares of Old Kern. It was thus a statutory insider when, on May 11, it extended its tender offer to include another 500,000 shares. We are quite unconvinced, however, that the situation had changed materially with respect to the possibilities of speculative abuse of inside information by Occidental. Perhaps Occidental anticipated that extending its offer would increase the likelihood of the ultimate success of its takeover attempt or the occurrence of a defensive merger. But, again, the expectation of such benefits was unrelated to the use of information unavailable to other stockholders or members of the public with sufficient funds and the intention to make the purchases Occidental had offered to make before June 8, 1967.
The possibility that Occidental had, or had the opportunity to have, any confidential information about Old Kern before or after May 11, 1967, seems extremely remote. Occidental was, after all, a tender offeror, threatening to seize control of Old Kern, displace its management, and use the company for its own ends. The Old Kern management vigorously and immediately opposed Occidental’s efforts. Twice it communicated with its stockholders, advising against acceptance of Occidental’s offer and indicating prior to May 11 and prior to Occidental’s extension of its offer, that there was a possibility of an imminent merger and a more profitable exchange. Old Kern’s management refused to discuss with Occidental officials the subject of an Old Kern-Occidental merger. Instead, it undertook negotiations with Tenneco and forthwith concluded an agreement, announcing the merger terms on May 19. Requests by Occidental for inspection of Old Kern records were sufficiently frus*599trated by Old Kern's management to force Occidental to litigate to secure the information it desired.
There is, therefore, nothing in connection with Occidental's acquisition of Old Kern stock pursuant to its tender offer to indicate either the possibility of inside information being available to Occidental by virtue of its stock ownership or the potential for speculative abuse of such inside information by Occidental. Much the same can be said of the events leading to the exchange of Occidental’s Old Kern stock for Tenneco preferred, which is one of the transactions that is sought to be classified a “sale” under § 16 (b). The critical fact is that the exchange took place and was required pursuant to a merger between Old Kern and Tenneco. That merger was not engineered by Occidental but was sought by Old Kern to frustrate the attempts of Occidental to gain control of Old Kern. Occidental obviously did not participate in or control the negotiations or the agreement between Old Kern and Tenneco. Cf. Newmark v. RKO General, 425 F. 2d 348 (CA2), cert, denied, 400 U. S. 854 (1970) ; Park & Tilford v. Schulte, 160 F. 2d 984 (CA2), cert, denied, 332 U. S. 761 (1947). Once agreement between those two companies crystallized, the course of subsequent events was out of Occidental’s hands. Old Kern needed the consent of its stockholders, but as it turned out, Old Kern's management had the necessary votes without the affirmative vote of Occidental. The merger agreement was approved by a majority of the stockholders of Old Kern, excluding the votes to which Occidental was entitled by virtue of its ownership of Old Kern shares. See generally Ferraiolo v. Newman, 259 F. 2d 342 (CA6 1958), cert, denied, 359 U. S. 927 (1959); Roberts v. Eaton, 212 F. 2d 82 (CA2 1954). Occidental, although registering its opinion that the merger would be beneficial to Old Kern shareholders, did not in fact vote at the *600stockholders’ meeting at which merger approval was obtained. Under California law, its abstention was tantamount to a vote against approval of the merger. Moreover, at the time of stockholder ratification of the merger, Occidental’s previous dealing in Old Kern stock was, as it had always been, fully disclosed.
Once the merger and exchange were approved, Occidental was left with no real choice with respect to the future of its shares of Old Kern. Occidental was in no position to prevent the issuance of a ruling by the Internal Revenue Service that the exchange of Old Kern stock for Tenneco preferred would be tax free; and, although various lawsuits were begun in state and federal courts seeking to postpone the merger closing beyond the statutory six-month period, those efforts were futile. The California Corporation Commissioner issued the necessary permits for the closing that took place on August 30, 1967. The merger left no right in dissenters to secure appraisal of their stock. Occidental could, of course, have disposed of its shares of Old Kern for cash before the merger was closed. Such an act would have been a § 16 (b) sale and would have left Occidental with a prima facie § 16 (b) liability. It was not, therefore, a realistic alternative for Occidental as long as it felt that it could successfully defend a suit like the present one. See generally Petteys v. Butler, 367 F. 2d 528 (CA8 1966), cert, denied, 385 U. S. 1006 (1967); Ferraiolo v. Newman, supra; Lynam v. Livingston, 276 F. Supp. 104 (Del. 1967); Blau v. Hodgkinson, 100 F. Supp. 361 (SDNY 1951). We do not suggest that an exchange of stock pursuant to a merger may never result in § 16 (b) liability. But the involuntary nature of Occidental’s exchange, when coupled with the absence of the possibility of speculative abuse of inside information, convinces us that § 16 (b) should not apply to transactions such as this one.
*601IY
Petitioner also claims that the Occidental-Tenneco option agreement should itself be considered a sale, either because it was the kind of transaction the statute was designed to prevent or because the agreement was an option in form but a sale in fact. But the mere execution of an option to sell is not generally regarded as a “sale.” See Booth v. Varian Associates, 334 F. 2d 1 (CA1 1964), cert, denied, 379 U. S. 961 (1965); Allis-Chalmers Mjg. Co. v. Gulf & Western Industries, 309 F. Supp. 75 (ED Wis. 1970); Marquette Cement Mjg. Co. v. Andreas, 239 F. Supp. 962 (SDNY 1965). And we do not find in the execution of the Occidental-Tenneco option agreement a sufficient possibility for the speculative abuse of inside information with respect to Old Kern’s affairs to warrant holding that the option agreement was itself a “sale” within the meaning of § 16 (b). The mutual advantages of the arrangement appear quite clear. As the District Court found, Occidental wanted to avoid the position of a minority stockholder with a huge investment in a company over which it had no control and in which it had not chosen to invest. On the other hand, Tenneco did not want a potentially troublesome minority stockholder that had just been vanquished in a fight for the control of Old Kern. Motivations like these do not smack of insider trading; and it is not clear to us, as it was not to the Court of Appeals, how the negotiation and execution of the option agreement gave Occidental any possible opportunity to trade on inside information it might have obtained from its position as a major stockholder of Old Kern. Occidental wanted to get out, but only at a date more than six months thence. It was willing to get out at a price of $105 per share, a price at which it had publicly valued Tenneco preferred on May 19 when the Tenneco-Old Kern agreement was announced. *602In any event, Occidental was dealing with the putative new owners of Old Kern, who undoubtedly knew more about Old Kern and Tenneco’s affairs than did Occidental. If Occidental had leverage in dealing with Tenneco, it is incredible that its source was inside information rather than the fact of its large stock ownership itself.
Neither does it appear that the option agreement, as drafted and executed by the parties, offered measurable possibilities for speculative abuse. What Occidental granted was a “call” option. Tenneco had the right to buy after six months, but Occidental could not force Tenneco to buy. The price was fixed at $105 for each share of Tenneco preferred. Occidental could not share in a rising market for the Tenneco stock See Silverman v. Landa, 306 F. 2d 422 (CA2 1962). If the stock fell more than $10 per share, the option might not be exercised, and Occidental might suffer a loss if the market further deteriorated to a point where Occidental was forced to sell. Thus, the option, by its very form, left Occidental with no choice but to sell if Tenneco exercised the option, which it was almost sure to do if the value of Tenneco stock remained relatively steady. On the other hand, it is difficult to perceive any speculative value to Occidental if the stock declined and Tenneco chose not to exercise its option. See generally Note, Put and Call Options Under Section 16 of the Securities Exchange Act, 69 Yale L. J. 868 (1960); H. Filer, Understanding Put and Call Options 96-111 (1959); G. Leffler, The Stock Market 363-378 (2d ed. 1957).
The option, therefore, does not appear to have been an instrument with potential for speculative abuse, whether or not Occidental possessed inside information about the affairs of Old Kern. In addition, the option covered Tenneco preference stock, a stock as yet unissued, unregistered, and untraded. It was the value of this *603stock that underlay the option and that determined whether the option would be exercised, whether Occidental would be able to profit from the exercise, and whether there was any real likelihood of the exploitation of inside information. If Occidental had inside information when it negotiated and signed the option agreement, it was inside information with respect to Old Kern. Whatever it may have known or expected as to the future value of Old Kern stock, Occidental had no ownership position in Tenneco giving it any actual or presumed insights into the future value of Tenneco stock. That was the critical item of intelligence if Occidental was to use the option for purposes of speculation. Also, the date for exercise of the option was over six months in the future, a period that, under the statute itself, is assumed to dissipate whatever trading advantage might be imputed to a major stockholder with inside information. See Comment, Stock Exchanges Pursuant to Corporate Consolidation: A Section 16 (b) “Purchase or Sale?,” 117 U. Pa. L. Rev. 1034,1054 (1969); Silverman v. Landa,, supra. By enshrining the statutory period into the option, Occidental also, at least if the statutory period is taken to accomplish its intended purpose, limited its speculative possibilities. Nor should it be forgotten that there was no absolute assurance that the merger, which was not controlled by Occidental, would be consummated. In the event the merger did not close, the option itself would become null and void.
Nor can we agree that we must reverse the Court of Appeals on the ground that the option agreement was in fact a sale because the premium paid was so large as to make the exercise of the option almost inevitable, particularly when coupled with Tenneco’s desire to rid itself of a potentially troublesome stockholder. The argument has force, but resolution of the question is very much a matter of judgment, economic and otherwise, and the *604Court of Appeals rejected the argument. That court emphasized that the premium paid was what experts had said the option was worth, the possibility that the market might drop sufficiently in the six months following execution of the option to make exercise unlikely, and the fact that here, unlike the situation in Bershad v. McDonough, 428 F. 2d 693 (CA7 1970), the optionor did not surrender practically all emoluments of ownership by executing the option. Nor did any other special circumstances indicate that the parties understood and intended that the option was in fact a sale.30 We see no satisfactory basis or reason for disagreeing with the judgment of the Court of Appeals in this respect.31
The judgment of the Court of Appeals is affirmed.
So ordered.
