MUMBAI (Reuters) - India's stock markets edged lower on Wednesday, tentatively heading for their second straight decline, as a steep fall in China's markets revived global risk aversion, while caution ahead of key corporate earnings results also weighed on sentiment.
China's share markets slumped 3.5 percent, the worst daily performance in five weeks, as a correction in small caps deepened through the day.
But analysts said they expected the recent momentum in shares to continue should earnings come in better than expected.
Wipro , Idea Cellular and JSW Steel are among companies due to report their earnings later in the day.
"Quarterly results for the first two week are quite encouraging. Though it is quite early to predict, if this trend sustains, we are looking at good earnings season on our hand," HDFC said in an email to clients.
The benchmark BSE Sensex was down 0.25 percent after rising as much as 0.5 percent before China's markets started their steep falls.
