My concern exactly...Fed Chairman speaks tomorrow and option expiration Friday are two items of concern. It looks like profit taking ahead of tax increases, especially since the silver miners, or at least a couple of them have been good performers, was part of this decline, today, Thursday. One big seller begat more sellers. Glad I had a few puts on, and overwritten calls. Profit taking day on those tomorrow, though all too often on these smash downs the time to buy is right at the end of a big down day...Tomorrow may very well see a small inside day as the decline is digested and option players square off reducing volitility.
