NEW YORK, Oct 13 (Reuters) - The Dow and S&P 500 slipped on Thursday after JPMorgan's earnings and China's soft trade data revived worries about the impact of slower growth on profits.
The declines put an end to three straight days of gains that capped off a 12 percent increase in the S&P 500 since hitting a low on Oct. 4. The Nasdaq stayed in positive territory, helped by semiconductor shares.
Some analysts said a pause was in store for the market, given the S&P 500's recent advance. The benchmark S&P 500 has had its largest seven-day rise since March 2009 on growing optimism that European leaders will find a way to contain the region's debt problems.

Healthy U.S. profits have been among the biggest drivers for stocks since their March 2009 lows.
The Dow Jones industrial average <.DJI> fell 40.72 points, or 0.35 percent, to end at 11,478.13. The Standard & Poor's 500 Index <.SPX> shed 3.59 points, or 0.30 percent, to 1,203.66. But the Nasdaq Composite Index <.IXIC> gained 15.51 points, or 0.60 percent, to close at 2,620.24.

"Christmas came early for Google shareholders," said Colin Gillis, an analyst at BGC Partners. "The digital economy is still strong. Google is capturing all the economics from this, and we are moving into the sweet spot when investors want to own Google."
