The major indexes made tiny moves Wednesday, and the Nasdaq ended a mild four-day win streak. Volume fell on both exchanges, extending the current thin trading activity. The Nasdaq composite fell 1 point. The S&P 500 ended fractionally higher to close a hair above the historic 2000 price level. Small caps didn’t move much, either. The S&P SmallCap 600 was down just 0.2%. The Russell 2000 also edged 0.2% lower.
