Stock futures opened modestly higher on Tuesday, driven by a further drop in oil prices and a cease to the fighting between Russia and Georgia. Less than two hours before the bell, Dow Jones Industrial Average futures rose about 10 points to 11779. S&P 500 and Nasdaq 100 futures were little-changed, though index futures were generally off their earlier lows. Crude-oil futures slid further, falling to a three-month low as a stronger dollar and weakening crude demand from China weighed on investor sentiment. The front-month futures contract declined by 84 cents to $113.61 a barrel in electronic trade. Oil has fallen more than $30 from its July 11 high of $147.27.
