Investors are focusing on the release of the minutes from the Federal Reserve's September policy meeting that will reveal policymakers' views on the progress of the U.S. economy and its ability to absorb an interest rate hike this year.
The markets are likely to be more volatile as the third-quarter earnings season will test relatively high valuations of stocks.

At 9:44 a.m. ET the Dow Jones industrial average was down 40.68 points, or 0.22 percent, at 18,087.98, the S&P 500 was down 3.22 points, or 0.15 percent, at 2,133.51 and the Nasdaq Composite was down 14.51 points, or 0.28 percent, at 5,232.28.
Fortinet shares plunged 12.2 percent after the cybersecurity company cut third-quarter revenue and profit forecast. Shares of rivals Palo Alto and Fireeye also fell.
