 NEW YORK, Feb 23 (Reuters) - U.S. stock index futures rose
on Wednesday, a day after Wall Street suffered its worst
session since August on geopolitical turmoil in Libya.
                                
 The unrest kept U.S. crude futures climbing to a 2-1/2 year
peak above $96 a barrel. Markets were concerned the turmoil
could spread to other top oil producers in the region and cut
more output, weighing on energy stocks. [O/R]

 "Investors are definitely eyeing the situation with
caution, but the market here is understanding that Libya is not
a big oil producer and most of its oil goes to Europe," said
Robert Pavlik, chief market strategist at Banyan Partners LLC
in New York.
                                
 "But if this spreads further from here to a bigger oil
producer, that will be a game changer since it will directly
impact us here."
