James Gorman, chairman and chief executive officer of Morgan Stanley, will have less time to boost the bank's stock price if he wants to reap big profits from his annual bonus. Options awarded to Gorman and five other top executives for 2012 will expire in five years, Morgan Stanley disclosed in regulatory filings last month. About 75 percent of executive options granted by companies in the Standard & Poor's 500 Index have 10-year terms, according to Aaron Boyd, director of research at Equilar Inc., a compensation data firm based in Redwood City, California.
