Stock market recap: Benchmark indices Sensex and Nifty ended largely unchanged in volatile trade on Tuesday as profit-taking in IT and blue-chip banking stocks, high crude oil prices and caution ahead of the US Federal Reserve’s policy decision kept investors on edge. The Sensex fell 8.08 points, or 0.01%, to close at 73,598.67, while the Nifty shed 3.45 points, or 0.02%, to settle at 22,749.75. Broader markets, however, outperformed the benchmarks on strong buying interest.
