The market has turned against the speculators who call themselves risk arbitragers. For most of the year, they had made all their money buying shares of companies later acquired at sharply higher prices by other companies. In a single takeover, that of Conoco by Du Pont Corp., the arbs pocketed tens of millions of dollars. Expecting other windfalls, they promptly plowed the cash into such hot takeover prospects as Cities Service Co., Kerr-Mcgee corp., Marathon Oil Co., Newmont Mining Corp. And a dozen others.
Like the tulip boom, it all went bust. The takeovers either never came off or got so dicey and distant as to frighten even the most risk-minded arbs. Some have turned to day trading, buying or selling shares in the morning and closing out their positions in the afternoon. A trader may hold a position for as long as forty-five seconds or so before closing it for an eighth or sixteenth of a point.
