The maniacs who dominate in this stock left a relatively rare and unquestionably bullish island-gap reversal on the hourly chart yesterday, threatening bears with a frontal assault if they should grow too bold. Since Goldman is still our favorite bellwether, we should take the threat seriously to the extent that the stock is capable of dragging the entire market higher if it catches fire.  I had suggested a mechanically inspired short in the SKF Ultrashort Financials — a bullish play on the banks — and this latest development in Goldman seems to explain why SKF’s rally could be short-lived.  Instead of shorting SKF, though, let’s speculate modestly in Goldman, bidding 2.10 on the opening for two September 170 calls (GPYIN). If the order goes unfilled, lower the bid to 1.90 and leave it in for the remainder of the day.
