Insider Trading Charges Filed: The Security and Exchange Commission said it filed charges against investors who allegedly snapped up CBI Industries Inc. stock just days before Praxair Inc. announced a takeover bid for the company. The announcement came just hours after CBI, a carbon dioxide and industrial gas producer, rejected the $2.1-billion takeover bid by Praxair, of Danbury, Conn., the largest industrial gas company in the Western Hemisphere. The defendants stand to realize about $1.3 million from the illegal trades, the SEC contended, based on CBI’s stock price, which jumped $10.625, or 53%, the day the bid was announced.
