According to market people on CNBC, the people selling are fraidy cats, and the "pros" are buying on the dips. Unless your time frame is within a year or two (and no you should not in the market anyway), 9500 seems like a great time to get in. In 10-20 years, you got a huge discount from 6-12 months ago. I'd buy 20% now, and keep investing when it has a bad day. There's no such thing as a floor, but given some companies are selling at 3 times earnings, it's time to bargain hunt. I don't see XOM or WMT hurting an iota more than they were a week ago(it's easy to argue WMT is helped), and both are off $5 with the market. I'm no market timer, but if you are, time to start dipping your toes in.
