U.S. stock advances are expected to run into resistance next week, following the longest winning streak since January 2011, as a lack of fresh incentives and opacity in Europe catch up with equities.

The tone and the tenor of the Federal Reserve minutes due on Wednesday will also dictate the market's mood as investors look for more clarity on possible additional economic stimulus measures from the central bank.

"The stock market has enjoyed a nice run in recent weeks, but moving above the April highs may prove to be a challenge. Bull markets, like bear markets, need constant feeding," said Alan Gayle, a senior investment strategist at Ridgeworth Investments. "The current run appears to have been fed by hopes for further global monetary stimulus and Quantitative Easing 3 and a lack of bad news from the EU--not strengthening economic momentum."

Since July 6, the Dow Jones Industrial Average (DJI) has advanced for six straight weeks for a cumulative 4% rise to 13,275 on Friday, closing in on April's high of 13,316.
