The market is selling off because QEII was underwhelming.
There are two big issues next week, the Fed and the election. The Fed is telegraphing that QEII will be less than the market is expecting. The market is expecting a Republican victory in the House. That is what I'm expecting. What if the Dems win instead? That's a negative. What if the GOP wins the Senate? That is a positive. But if it is anything other than the GOP winning both chambers, I would expect a sell the news reaction, which may be kicking in now.
Short term you're probably right. Markets rose anticipating a GOP victory. All that news is out and discounted.
I expect stocks will be higher some time next year, so I will be covering my shorts into this sell-off.
