Good day for: New blood, as the Dow Jones Industrial Average is adding insurer Traveler's Cos. and Cisco Systems Inc., and dropping Citigroup Inc. and General Motors. The updating of the Dow -- the best-known barometer of big-company stocks on Wall Street -- came as GM announced it was filing for bankruptcy protection under a government-driven restructuring that aims, among other things, to make the giant automaker much smaller.

Bad day for: Following the herd, as an investor who followed President Obama's March 3 advice to buy stocks would have reaped 32 percent returns if he had invested that day in the Standard & Poor's 500 index. "This is one of the more visible examples of how going against the crowd and taking a contrary position works out spectacularly well," investment strategist Ed Yardeni said. (MarketWatch)
