NEW YORK, Oct 31 (Reuters) - Robust corporate results helped world stock markets surge on Wednesday, bringing some relief to jittery investors after a brutal October that saw equities suffer one of their worst drops since the financial crisis ten years ago.
Strong earnings reports in the U.S. and Europe spurred a broad rally, despite data showing that China's factory growth slowed to its lowest in two years. Investors rushed into the U.S. dollar, sending it to a 16-month high while the offshore Chinese yuan languished at a 22-month low.
The MSCI world equity index .MIWD00000PUS , which tracks shares in 47 countries, rose 0.6 percent, but remains down 8.2 percent in October, its worst month since 2012. The index has dropped 13 percent from all-time highs hit in January.
Still, despite the broad rally, investors remained cautious.
"Ultimately I'm still of the belief that we are in for more downside and rallies are for selling, but squeezes in bear markets are not normally comfortable affairs," said Neil Campling, co-head of the global thematic group at Mirabaud Securities.
"I think a 2-3 day battle toward the top of the downtrend. Then we can return to the bigger picture - the mid-terms (U.S. elections), trade wars, rates etc. once a few shorts have been taken out of the tape."
The Dow Jones Industrial Average .DJI rose 314.71 points, or 1.27 percent, to 25,189.35, the S&P 500 .SPX gained 38.95 points, or 1.45 percent, to 2,721.58 and the Nasdaq Composite .IXIC added 175.69 points, or 2.45 percent, to 7,337.34.
The pan-European STOXX 600 index .STOXX rose 1.82 percent.
The dollar index .DXY , tracking it against a basket of six major currencies, rose 0.09 percent, with the euro EUR= down 0.22 percent to $1.1319.
"Euro zone growth figures have been disappointing and the Bank of Japan is striking a dovish stance at a policy meeting today so there is more room for the dollar to gain from current levels," said Paul Bednarczyk, director of G10 FX at Continuum Economics based in London.
The Chinese currency was on track for a loss of 1.4 percent in October, its seventh straight monthly decline and its longest losing streak on record.
Gold, set for its best month since January, dipped on the stronger dollar. Spot gold XAU= dropped 0.8 percent to $1,212.64 an ounce. U.S. gold futures GCcv1 fell 0.92 percent to $1,214.00 an ounce. recovery in global stocks, including gains overnight on Wall Street, pushed Treasury yields higher. Benchmark 10-year notes US10YT=RR last fell 13/32 in price to yield 3.1586 percent, from 3.109 percent late on Tuesday.

U.S. crude CLcv1 fell 0.33 percent to $65.96 per barrel and Brent LCOcv1 was at $75.71, down 0.32 percent on the day.
