We don't want to jinx it, but are things looking up? Friday was a big day on Wall Street, with the Standard & Poor's 500 index closing above 1,500 for the first time in more than five years. High U.S. earnings from Procter & Gamble and other companies were credited for the boost. The Dow Jones industrial average was also up by 0.51 percent, and the Nasdaq Composite Index saw a 0.62 percent jump. This was the fourth week in a row of gains for all three indexes.
