MUMBAI (Reuters) - Indian stocks ended flat in a volatile session on Wednesday as investors avoided risky bets ahead of the expiry of January derivatives contracts on Thursday and a U.S. Federal Reserve policy statement due later in the day.
The broader Nifty gained marginally to end 0.02 percent higher while the benchmark Sensex rose 0.03 percent at close.
