NEW YORK (MarketWatch) -- The U.S. stock market moved higher after the FOMC minutes revealed that policy-makers decided to end the Fed's bond purchases by October if the economy stays on track.

The Fed will make a $15 billion final reduction at its October meeting, after trimming it by $10 billion at each meeting up to that point.

The S&P 500 (SPX) gained 8 points, or 0.4%, to 1,971.78. The Dow Jones Industrial Average (DJI) added 72 points, or 0.4%, to 16,979.40. The Nasdaq Composite (RIXF) rose 26 points, or 0.6%, to 4,417.70.

"In the short-term, we are concerned that there is a bit of optimism about the second-quarter earnings. Expectations for overall markets are high and this lead to some short-term downside if companies come short," said Joe Bell, senior equity analyst at Schaeffer's Investment Research.

"We believe this quarter financials are likely to surprise on the upside, just because there is too much skepticism about the sector, the only one to deliver negative growth," Bell added.

Alcoa Inc. (AA) shares rallied 6.1% after the company said it swung to a second-quarter profit late Tuesday.

Shares of Gigamon Inc.(GIMO) sank 33% after the networking-hardware company lowered its second-quarter revenue guidance on Tuesday.

Container Store Group Inc. (TCS) shares plunged 9.5% after the organization-product company posted a loss of 7 cents, a penny more than expected. (Read more in Movers and Shakers column: http://www.marketwatch.com/story/alcoa-container-store-wd-40-are-stocks-to-watch-2014-07-09.)

In overseas markets, Europe's Stoxx 600 headed for its fourth day in the red, while the Hong Kong Hang Seng index lost 1.6% after softer-than-expected inflation data from China.

Crude-oil prices (CLQ4) were largely stable, while gold (GCQ4) moved higher. The dollar (DXY) was mostly higher.
