Just sector rotation. One by one the sectors are being taken out.....and shot. And this is not an exaggeration.
The two sectors I follow closest have been hit pretty hard, the SOX and BTK, bios. Both are full of small and mid cap story companies and right now the money is heading for the hills and safety. I also read this morning that some of the financial sectors aren't doing well either.
What seems to be holding up are commodities, precious metals, and of course oil and gas and even utilities are showing some life.
