Stocks continued to hold near their session highs late Monday amid hopes for Greece. The Nasdaq climbed 1.3% and the S&P 500 gained 0.9%. Meanwhile, the Dow Jones industrial average rallied 1%, with 28 of 30 issues higher. Microsoft (MSFT) and DuPont (DD) were the biggest percentage movers, up 2% each. Turnover was tracking higher on both major exchanges. But trade was only up a hair on the NYSE.
