Stocks kept to a recent trading range Tuesday afternoon as volume faded for a second straight session. The Nasdaq tacked on 0.5% while the S&P 500 and the Dow Jones industrial average added 0.8% and 0.9%, respectively. Volume fell across the board. The major indexes were staying within the trading range sketched by Friday’s sharp slide, pointing to a market that isn’t ready to move decisively up or down.
