Again, the BKX acts as a harbinger of things to come. For those who believe that the recent market sell-off came "out of the blue," I might agree if only looking at my charts of the major U.S. indices. But while I had no "sell" signal on the INDU, SPX, RUT, or NDX, until it was "too late", the BKX had a beautiful, clear "sell" signal on Feb 23. (Not to mention that the XBD had been lagging the major indices, and Mother Merrill had a "sell" signal way back on Jan 25.)
