Adding to the concerns, Switzerland\'s central bank said it would fight to keep the Swiss franc from rising past 1.20 francs against the euro, sending safe-haven flows surging to the dollar. European stocks were mixed. London climbed 1.06 percent in a modest rebound from Monday\'s brutal sell-off, but Paris dropped 1.13 percent while Frankfurt fell 1.0 percent. In Asia, Tokyo plummeted 2.21 percent to hit its lowest level since April 2009, while Seoul shed 1.07 percent and Sydney tumbled 1.60 percent.

The turnaround was boosted by positive data on the US service sector, which grew more than expected in August, according to a monthly survey by the Institute for Supply Management.

Any level above 50 indicates growth. \"Stocks received temporary relief from the August ISM Service Index,\" analysts at Briefing.com said in a research note.Investors hunting for bargains also helped the stock market pare its early losses, with gains by technology companies like Amazon (up 2.9 percent), Netflix (up 2.7 percent) and Apple (up 1.5 percent). \"The tech sector has been leading the market on its rally from the morning’s lows. It lent a bottom-fishing mentality,\" said Michael James, managing director at Wedbush Morgan Securities.Bank stocks ended the day with sharp losses, however, with Bank of America down 3.6 percent, Citigroup off 2.5 percent and JPMorgan Chase down 3.4 percent.
