The Sensex and Nifty ended lower on Tuesday as investors remained cautious ahead of the US Federal Reserve's policy statement this week.

The Fed is set on Wednesday to announce the start of a plan to trim its $4.5-trillion portfolio of assets, much of it amassed in response to the 2007-2009 financial collapse, marking another milestone in bringing to an end the crisis-era measures.

The broader NSE index, which hit a record high earlier in the session, closed down by 5.55 points or 0.05 per cent at 10,147.55. The benchmark BSE index closed lower by 21.39 points or 0.07 per cent at 32,402.37.

Among BSE sectoral indices, oil & gas index gained the most by 1.15 per cent, followed by realty 0.79 per cent, auto 0.61 per cent and power 0.41 per cent. On the other hand, metal index was down 0.58 per cent, capital goods 0.39 per cent, healthcare 0.34 per cent and consumer durables 0.32 per cent.

Top five Sensex gainers were Tata Motors (+4.58%), Kotak Bank (+1.63%), Cipla (+0.61%), ICICI Bank (+0.6%) and NTPC (+0.54%), while the major losers were Coal India (-2.49%), HDFC (-1.02%), L&T (-0.92%), State Bank of India (-0.87%) and Sun Pharma (-0.84%).

“People tend to be cautious around monetary policy meetings. There is a sense of cautious approach, especially for people investing in banks,” said Sudhakar Pattabiraman, head of research operations at William O'Neil India.

“Since we had a very good day at the market yesterday, there is some element of profit-booking happening.”

Asian shares wavered on Tuesday, bolstered by record highs on Wall Street, but hobbled by uncertainty as traders waited on a Federal Reserve meeting for clues on US monetary policy.

MSCI’s broadest index of Asia–Pacific shares outside Japan turned slightly higher after dipping into negative territory.

On Wall Street on Monday, the Dow Jones Industrial Average closed at a record high for the fifth straight session and the S&P 500 marked its second straight closing record high, as higher US Treasury yields helped lift financial shares.
