LONDON, Oct 31 (Reuters) - Stock markets bounced higher on Wednesday, bringing some relief after a brutal October in which equities have suffered one of their worst drops in a decade and spooked investor confidence.
Sino-U.S. trade tensions, concerns about global growth and higher U.S. interest rates and fears that corporate earnings are peaking have combined to shake financial markets in October, leaving most major markets in negative territory for the year.
That has spurred predictions that an almost decade-long bull-market has run its course.
Data overnight showing that China's factory growth slowed to its lowest in two years has reinforced worries about weakening growth stemming from the trade conflict with the United States, and followed disappointing euro zone growth data published on Tuesday. rushed into the dollar, sending it to a 16-month high while the offshore Chinese yuan was left to nurse another 22-month low.
A batch of positive earnings set a firmer tone for European stocks on Wednesday, although pan-European indexes are headed for their weakest month since August 2015.
The leading euro zone stock index .STOXX50E was up 1.5 percent in early trading, with the pan-European STOXX 600 .STOXX up 1.4 percent and Germany's DAX .GDAXI up 1.3 percent. Britain's FTSE 100 .FTSE increased 1.4 percent. gains follow Asia, where the MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS rose 1.4 percent, drawing support from gains on Wall Street.
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 is down 13 percent from all-time highs hit in January.
"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."
Fresh concerns over growth in Asia and the euro zone come as the U.S. economy continues to look in healthier shape, spurring fresh demand for the dollar.
The greenback, measured against a basket of currencies .DXY , scaled a fresh 2018 peak on Wednesday, while the euro laboured near $1.1352 EUR= , recovering slightly from losses earlier in the week.
