LONDON, Sept 29 (Reuters) - European shares partially recouped an early drop on Tuesday, supported after battered miner Glencore halted a slide in its share price, although top indexes lingered near their lows for 2015.
The pan-European FTSEurofirst 300 index was down 0.4 percent by 0958 GMT on Tuesday, having been down as much as 1.7 percent in early deals.
The index fell more than 2 percent on Monday, and the morning's early drop took it just 0.8 percent away from its low for 2015, set in August.
Miner Glencore surged 9 percent, having dropped 30 percent in the previous session to an all-time low, with several brokers saying worries over the commodities and mining company's debt pile were overdone.
"Momentum is against Glencore, but fundamentally the stock is very cheap, and we don't think that is justified," said Ankit Gheedia, equity and derivatives strategist at BNP Paribas, adding the drop in the broader market in recent weeks had also been overdone.
"Fundamentally the falls have gone too far, but the momentum tends to persist for a bit longer, even while the fundamentals are fine."
The FTSEurofirst 300 is down 20 percent since April, when it hit its highest level since 2000. Germany's DAX hit a record high of 12,390.75 points in April but is now some 24 percent below those levels.
The DAX and other world stock markets have lost ground in the past few months partly due to signs of a slowdown in China, which has also hit the commodity sector as China is a major consumer of metals and oil.
The prolonged fall in metals prices has been one of the reasons behind Glencore's stock market slump.
U.S. bank Citigroup said Glencore should even consider going private via a management buyout if the market pounding continued, and kept a "buy" rating on Glencore shares.
The STOXX Europe 600 Health Care index was the biggest sectoral faller, dropping 1.6 percent after U.S. pharmaceutical and biotech stocks fell overnight.
The U.S. biotech sector was hit after U.S. Democratic lawmakers on Monday attacked "massive" price increases of two heart drugs from Valeant Pharmaceuticals.
In Europe, British healthcare group Shire was down by 3.8 percent while Switzerland's BB Biotech retreated 2.6 percent.
"The momentum is to the downside for those biotech stocks," said Terry Torrison, managing director at Monaco-based McLaren Securities.
Building supplier Wolseley fell 12 percent after lowering its second half revenue growth forecast, saying it expected markets in North America and Britain to remain challenging.
