According to market experts, going into the Q2 results season, the market has been expecting good numbers from IT and banking.

"HCL Tech's good results confirm the optimistic expectations and the banking results, particularly from the leading private banks, also are likely to be good. Unlike IT stocks where there is only limited valuation comfort, the banking stocks offer decent valuation comfort and, therefore, have the potential to move up from the present levels," the analysts said.

Asian markets are witnessing a boom. Except for Hong Kong, the markets of Tokyo, Bangkok, Jakarta and Seoul are trading in the green. The US stock markets closed in the green on the previous trading day.
