Law professor Peter Henning, a former SEC attorney, is quoted in an article about a flurry of stock option trading in a St. Louis manufacturing company just before the company's sale to another corporation. He indicates that such trading would raise a red flag among securities regulators. "The options market is fairly well-regulated," Henning points out. "You tend not to have those kinds of spikes." He adds that such trading in call options "is certainly going to get the attention of the SEC."
