Stocks percolated in lower volume Friday but ended with a nice splash to close high in the day’s price range. The Nasdaq grabbed an 0.7% gain, while the S&P 500 took the smaller 0.4% portion. The IBD 50 added 0.3%. The day’s signature move came in the final two hours as the indexes rose without interruption. Volume slowed on the eve of the three-day weekend. Trade resumes Tuesday after the Presidents Day holiday Monday.
