Case Brief Summary & Legal Analysis
tl;dr: A trader was convicted of manipulating a stock price to benefit arbitrageur Ivan Boesky. The appellate court reversed, finding the government’s evidence of manipulative intent, which hinged on an ambiguous phone call and circumstantial facts, was insufficient to prove guilt beyond a reasonable doubt.
Legal Significance: This case establishes a high evidentiary standard for proving manipulative intent under Rule 10b-5 in open-market transactions. It holds that ambiguous evidence, which is as consistent with a legitimate investment purpose as with guilt, is insufficient to support a manipulation conviction.

Case Facts & Court Holding
Key Facts & Case Background
Ivan Boesky, a prominent arbitrageur, held a large position in Gulf & Western (G&W) stock and sought to have the company buy him out at $45 per share. G&W’s chairman agreed to repurchase the shares at the “last sale” price on the NYSE. At the time, the stock was trading below $45. Boesky then called defendant John Mulheren, a trader, and stated that while he wouldn’t pay more than $45 for G&W stock, “it would be great if it traded at 45.” Mulheren replied, “I understand.” Shortly thereafter, Mulheren’s firm purchased 75,000 shares of G&W, causing the market price to rise from $44 7/8 to $45. Immediately after the price hit $45, Boesky sold his block of shares to G&W at that price. Mulheren’s firm lost over $64,000 on its G&W trades that day. Mulheren was charged with and convicted of conspiracy and securities manipulation under Section 10(b) and Rule 10b-5. The government’s theory was that Mulheren purchased the stock for the sole purpose of raising the price for Boesky’s benefit.
