LONDON, Aug 26 (Reuters) - The pan-European FTSEurofirst 300 index pared losses of nearly 3 percent on Wednesday, despite persistent concerns about China's economy, on hopes of further monetary support from the European Central Bank.
The index traded down 0.8 percent at 1,396.14 by 1110 GMT, having been as much as 2.8 percent lower, after an ECB official said that commodity price falls put the bank's inflation target at risk, and that it was ready to act if needed.
The FTSEurofirst, which risks posting its biggest monthly loss in seven years, suffered its worst one-day drop since November 2008 on Monday, and rallied in the following session after a Chinese interest rate cut boosted markets.
Having closed in negative territory on Tuesday, U.S. futures pointed to a positive start on Wall Street.
"On a short-term basis I am willing to increase my risk and buy. I believe the market is offering opportunities," Alliance Bernstein European equities portfolio manager Michele Patri said.
"But medium term the situation looks complex. When you see how stocks exposed to global growth are performing, you can really see how investors do not have faith in the outlook."
Many commodity-related stocks recovered from early weakness to trade higher, as oil and metals prices bounced off their lows. Shares in BHP Billiton rose 2.5 percent having been negative, helped also by an upgrade from RBC.
But many investors remain worried by signs of a Chinese economic slowdown and deflationary pressures resulting from Beijing's devaluation of its yuan currency this month.
Germany's DAX weakened by 0.6 percent, leaving it some 19 percent below a record high reached in April.
"I think the downtrend is still intact because of the bigger picture of anaemic global economic growth. Any reasonable rally on the markets will be sold into," Berkeley Futures' associate director Richard Griffiths said.
However, some brokers and fund managers are arguing for a European stock market recovery as signs of an economic pickup in the United States and Europe help to offset weakness in China.
Morgan Stanley's strategists expected the market to be higher in three months' time.
They tipped 20 shares they considered to be "oversold", including chipmaker ARM, carmaker BMW and luxury goods group LVMH - all of which have been hit by the Chinese market turmoil.
Betting firms Paddy Power and Betfair surged, both rallying nearly 20 percent as investors welcomed their plans to merge.
