Financial firms take center stage this week. JPMorgan Chase (JPM), Wells Fargo (WFC), Goldman Sachs (GS), Bank of America (BAC) and BlackRock (BLK) are few of the big banks and asset managers that will post their latest results. According to estimates compiled by FactSet, analysts predict that earnings for the S&P 500 plummeted nearly 45%, which would be the biggest drop since a 69% plunge during the depths of the Great Recession in the fourth quarter of 2008. #S&P500# #BearishSentiment# #StockMarket#
