Indian equity markets recovered from early losses to end flat on Tuesday, with the benchmark Sensex index closing down just 0.09% after falling as much as 500 points at the open. The recovery was attributed to short-covering by bears who had bet against the market as the Sensex lost over 1,500 points in the prior sessions due to the collapse of Lehman Brothers and Merrill Lynch acquisition. Analysts saw signs that investors who had sold stocks hoping for further declines covered their positions by repurchasing shares.
