as a continuation to my review of the key financial stocks tonight, here’s the daily charts of GS and C highlighting the massive overhead supply (i.e.-resistance) they now face. whether these stocks turn down soon or not, i’m willing to bet that the next 20-30% move from above these levels will be a whole lot more difficult than the last 20-30%. if i were a buy-and-hold investor tucking away a bunch of bank stocks, at the very least i would consider selling covered calls going forward.
