NEW YORK (Reuters) - Global equity markets reached a two-year low on Tuesday as the outlook for raw materials prices and emerging markets remained bleak, while U.S. biotech shares attempted to stabilise after a recent selloff.
Commodity prices edged up but held near multi-year lows on concern over an economic slowdown in major raw material consumer China. U.S. stocks turned higher in a choppy session, as biotechs were volatile following a seven-session losing streak.
The S&P 500 dropped 2.6 percent in the prior session for its fifth straight loss, moving closer to August lows that analysts see as a key support level.
"It's typical of a market that is trying to find the bottom but it is hard because there is so much uncertainty," said

Platinum fell to a low of $894 an ounce, its lowest since December 2008, on fears that the emissions scandal surrounding German carmaker Volkswagen (XETRA:VOWG) could hit demand from the auto sector. It last stood at $912.74, down 0.4 percent.
The pan-European FTSEurofirst 300 index closed down 0.6 percent, recovering from a steeper fall led by biotech shares.
U.S. biotechs reversed initial declines, however, to show a gain of 1.6 percent. The Nasdaq Biotech Index fell nearly 20 percent over the prior seven sessions on concerns over government intervention in drug pricing.
