Magazine Cites Suspicious Trading in 11 Stocks: BusinessWeek notified regulators after detecting suspicious trading in the stocks mentioned in its Inside Wall Street column before publication. The weekly publication of McGraw-Hill Cos. said it reported its concerns to the Securities and Exchange Commission and the New York, American and Nasdaq stock exchanges on Jan. 19. It said it decided to disclose the suspicious trading in part to protect the integrity of the magazine and said it was cooperating with regulators. The magazine said it has moved to strengthen safeguards against leaks in recent years after 11 people, including three stockbrokers, were convicted of, or settled charges related to, insider trading on information in the column.
