NEW YORK, Jan 21 (Reuters) - U.S. stock index futures fell on Wednesday after a disappointing outlook from IBM and as investors reduced their exposure ahead of an upcoming European Central Bank (ECB) meeting that could result in new stimulative measures.
The ECB is expected to announce a bond-buying program on Thursday to boost the region's flagging economy. Market participants have been looking for more aggressive measures to combat the risk of deflation that has grown alongside a drop in oil prices. If the ECB doesn't announce a new program, or unveils a smaller one than investors are looking for, that could exacerbate market volatility.
Crude oil rose 1.7 percent after dropping nearly 5 percent on Tuesday, though it remained near multiyear lows. ExxonMobil Corp was up 0.3 percent to $91.35 before the bell.
International Business Machines Corp reported lower-than-expected revenues late Tuesday and gave a 2015 profit target below estimates. Shares of the Dow component fell 2.4 percent to $152.13 in premarket trading.
Another member of the Dow, UnitedHealth Group Inc, rose 1.2 percent to $106.90 in light premarket trading after reporting fourth-quarter earnings that beat expectations.
Netflix Inc jumped 18 percent to $411 and was one of the most active on Nasdaq premarket, a day after the streaming and rental video company said it was growing faster overseas than previously expected, offsetting slower U.S. growth. It also posted an adjusted profit that was much stronger than expected.
With 8 percent of S&P 500 companies reporting, 75 percent topped earnings expectations, according to Thomson Reuters data. About 52 percent beat on revenue.
Traders also digested President Barack Obama's State of the Union address, delivered late Tuesday, in which he struck a defiant tone with the new Republican-controlled Congress, calling for higher taxes on the rich.
Qualcomm Inc fell 3.1 percent to $70.25 premarket after Bloomberg reported that Samsung Electronics Co Ltd would not use Qualcomm's processors for the next version of its flagship Galaxy S smartphone.
