Going ahead, the levels of 10,550-10,560 would be seen as immediate hurdle, followed by 10,620 and unless index does not climb this wall, we are likely to see volatile movement with a negative bias. On the lower side, 10,440 remains to be a crucial support level and a move beyond 10,440 would extend the correction up to the levels of 10,400-10,370. Stocks to watch out: SRF, Corporation Bank, SML Isuzu, CG Power, Piramal Enterprises, Prestige Estate, Union Bank of India, Dilip Buildcon and 3i Infotech.
