NEW YORK (Reuters) - Stock index futures looked poised on Thursday to extend its recent rally, even as a weak reading on the labor market underlined the headwinds facing the economy's recovery.
The S&P 500 index was on track for a third day of gains, after Wednesday's advance took it to its highest level since May. The rally has largely been driven by corporate earnings, and investors were cheered by IBM
Futures were off session highs early on Thursday as jobless claims rose more than expected in the latest week, the latest in a string of data pointing to weakness.
"The labor market is clearly not recovering," said David Carter, chief investment officer at Lenox Wealth Advisors in New York. "We don't expect employment to recover strongly anytime soon."

S&P 500 futures rose 7.2 points and were above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures added 43 points and Nasdaq 100 futures rose 16.5 points.
The S&P is on track to notch a third straight day of gains on Thursday, having advanced 1.4 percent over the past two sessions.
Investors have been concerned that the debt crisis in Europe and signs of slowing growth worldwide would hurt corporate profits, but thus far, most companies have beaten the recently moderated expectations of analysts. With 10 percent of the S&P 500 having reported, according to the latest Thomson Reuters data, 73 percent have exceeded expectations.
"What IBM did, and what other companies are indicating, is that earnings will not be as poor as people felt was possible," said Rick Meckler, who helps oversee $2 billion as president of LibertyView Capital Management in New York.
"When you see earnings hold up in a weakening economy, that allows stocks to keep their momentum and suggests these companies could really advance when the economy picks up."

Weak economic data recently has amplified hopes the Federal Reserve would step in with measures to boost growth. On Wednesday, Fed Chairman Ben Bernanke repeated in congressional testimony the Fed's pledge to act if the economy needed it. Later in the day, the Fed's anecdotal Beige Book survey showed the economy is still struggling.
