The BSE Sensex edged higher on Tuesday, rising for the fifth day in the last six sessions, led by gains in Reliance Industries, on hopes the government will soon approve the company's investment plans for the KG-D6 block.
Analysts said markets would closely track the progress on a crucial vote in the parliament on foreign direct investment in multi-brand retail sector and other reform initiatives for the near term.
Hopes of more open market operations and some monetary easing by the Reserve Bank of India by December-end also aided sentiment.
"Going ahead, market's movement will depend on the parliament's behaviour. If the government wins the FDI vote, it will be taken positively, but if they lose then selling cannot be ruled out," said R.K. Gupta, managing director at Taurus Mutual Fund.
However, there are apprehensions that while the government will be able to muster support for the bill in the Lok Sabha, it will still remain pending in the Rajya Sabha, Gupta added.
The benchmark BSE Sensex gained 0.22 percent, or 42.80 points, to end at 19,348.12.
The broader Nifty rose 0.31 percent, or 18.30 points, to end at 5,889.25, finding resistance around psychologically important 5,900 level.
