Wall Street is greeting what is expected to be the worst earnings season since 2009 with a gigantic shrug. Though there has been some selling in recent weeks, there’s been no panic dumping of stocks, even though forecasts for S&P 500 first-quarter earnings have tumbled since Jan. 1, thanks to the surging dollar, falling oil prices and another severe winter. The earnings season unofficially kicks off Wednesday with results from aluminum company Alcoa (AA.N).
