Banyan Partners' chief market strategist Robert Pavlik said although the S&P 500 is up about 8.8% for the year, the market hasn't yet reached a top. In the short term, there's still more room to run, given that many investor uncertainties have been alleviated. Such uncertainties include soft, historical trading patterns for September, geopolitical issues, the Federal Reserve's medium-term policy outlook, and selling associated with investors freeing up cash for the Alibaba IPO, Pavlik said.
Existing U.S. home sales for August fell 1.8% on a seasonally adjusted rate to 5.05 million units vs. the 0.8% gain economists expected. The decline halted four straight months of gains.

Merck said the combined companies will be able to serve life science customers in a supply chain that can support the delivery of more than 300,000 products to life science customers around the world.
