June 15 (Reuters) - U.S. stock index futures fell on Thursday, pulled lower by technology stocks, while investors fretted about the Federal Reserve's outlook on monetary policy amid weak economic data.
* Apart from raising interest rates and forecasting one more hike for 2017 on Wednesday, the Fed laid out its first clear outline to start trimming its $4.2 trillion balance sheet "relatively soon".
* While the rate hike was widely expected, a clutch of weak economic data, including Wednesday's poor inflation numbers, raised questions whether the U.S. economy was strong enough to withstand further tightening. Policymakers, however, viewed the soft data as transitory.
* A Washington Post report that U.S. President Donald Trump was being investigated for possible obstruction of justice added to the jitters.
* Nasdaq futures were worst hit on Thursday as a selloff in technology stocks threatened to resume amid valuations worries.
* Technology heavyweights such as Apple, Microsoft and Alphabet, which were hit hard by the selloff earlier in the week, were in the red in premarket trading on Thursday.
* Chip stocks, including Nvidia, Micron Tech and Advanced Micro Devices, were down more than 2.5 percent each.
* Also lower were shares of big banks including Bank of America, Citigroup, Goldman Sachs and Morgan Stanley.
* Investors are likely to keep a sharp eye on a string of economic data on Thursday to get a deeper insight into the health of the U.S. economy.
* Top tier data due at 8:30 a.m. ET (1230 GMT) include reports on industrial production, manufacturing output and weekly jobless claims.
* Brent crude hit six-week lows as OPEC failed to curb oversupply.
Futures snapshot at 7:09 a.m. ET:
* Dow e-minis were down 71 points, or 0.33 percent, with 12,212 contracts changing hands.
* S&P 500 e-minis were down 14.25 points, or 0.58 percent, with 72,524 contracts traded.
* Nasdaq 100 e-minis were down 56.75 points, or 0.99 percent, on volume of 9,835 contracts. (Reporting by Yashaswini Swamynathan in Bengaluru; Editing by Anil D'Silva)
