The Standard & Poor's 500 index was up five points, or 0.3 percent, to 1,955, shortly after noon.

On Friday, the S&P 500 index notched another record high, its eighth in 10 trading days.
The market has been on a steady climb for three weeks running, pulling the S&P 500 up 4 percent in a month. Judging by some measures, that sudden success makes it look like the S&P 500 has moved “too far, too fast,” said Joe Bell, senior equity analyst at Schaeffer's Investment Research.
But there are still plenty of traders laying bets against the market, and people have recently taking billions out of stock funds. Last week, for instance, the Investment Company Institute reported that investors pulled $2.4 billion out of U.S. stock funds in the week ending May 28.
“We don't think there's an overwhelming amount of optimism right now,” Bell said.
