Jan 13 (Reuters) - U.S. stock index futures gave up some gains on Friday after disappointing quarterly reports from Bank of America and Wells Fargo.
Shares of Bank of America fell 0.7 percent to $22.76 in premarket trading after the lender's quarterly profit beat estimates, but its revenue fell short.
Wells Fargo was down 1 percent at $53.95 after it reported a fall in profit and its revenue fell short of market expectations.
JPMorgan was up 0.2 percent at $86.39 after its quarterly profit and revenue both topped analysts' expectations.
The combined profit of S&P 500 companies is estimated to have risen 5.7 percent in the fourth quarter, largely helped by financial companies, according to Thomson Reuters I/B/E/S.
"There is a lot of optimism regarding the financial sector but any kind of cautious statement from them might cause a bit of a pullback," said Scott Brown, chief economist at Raymond James in St. Petersburg, Florida.
"All the changes that are being proposed for the sector is going to take some time, it's not going to happen right away."
Dow e-minis were up 11 points, or 0.06 percent, with 16,237 contracts changing hands at 8:35 a.m. ET (1335 GMT).

The S&P financial sector has jumped about 17 percent since the Nov. 8 U.S. presidential election, outpacing the S&P 500's 6.1 percent rise, boosted by hopes of deregulation and increased interest rates.
U.S. stocks overall have been on the rise since the election on optimism that U.S. President-elect Donald Trump's policies to boost infrastructure spending and reform corporate taxes will benefit the economy.
But, analysts fear the market has run too far too soon, with Trump's policies expected to hit legislature hurdles, and with stock valuations stretched.
Blackrock Chief Executive Larry Fink told CNBC that if the roll out of growth initiatives by Trump are slower, then the markets are ahead of themselves.
