Cramer told investors to take advantage of the drop in a number of bank stocks caused by the poor earnings report from American Express (AXP). Cramer’s “fortress banks” JPMorgan (JPM), US Bancorp (USB), Wells Fargo (WFC) and Bank of America (BAC) all dropped in after-hours trading following the AXP report. Cramer explained that the drop in American Express was due to the fact company has no customer deposit base to rely on and can only make money off of transaction fees, membership fees and interest on loans. He compared American Express to major retailer Target (TGT) which has a large credit card business, but also can fall back on its merchandise sales, which American Express can’t do. Cramer said investors should look to buy Wachovia, Bank of America (BAC), US Bancorp (USB) and JP Morgan (JPM) off the AXP earnings disappointment.
