U.S. stock futures rose about an hour before the start of trading today, as investors were encouraged by yesterday's Lehman Brothers sell-off. S&P 500 futures rose 2.40 points and were above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures climbed 10 points and Nasdaq 100 futures gained 7.75 points. Lehman is going to post a quarterly loss of about $3.9 billion. It has decided to slash its annual dividend.
