MUMBAI The BSE Sensex edged higher on Friday to touch two-year high, posting its strongest weekly performance since the end of November, as oil companies such as ONGC rose on hopes a proposed change in the government's pricing formula would boost gas prices.
Software services exporters such as Tata Consultancy Services (TCS.NS) also rose on expectations upcoming October-December earnings results would beat expectations and that the sector would guide for an improved outlook in 2013.
Infosys (INFY.NS) will kick off earnings on January 11, at a time when results are gaining particular relevance given some analysts worry about potential complacency after strong gains in 2012 have continued into the new year.
India VIX .NIFVIX, also considered by some investors as a fear gauge, is just 2.5 percent away from its all-time lowest close.
"We have already seen advance tax numbers, so in the near term one has to see how the earnings season pans out," Kaushik Dani, fund manager at Peerless Mutual Fund, said.

Shares in upstream oil and gas companies rallied on hopes that the pricing formula recommended by a government-appointed panel that looked into oil and gas exploration contracts would be approved by the government.

Oil and Natural Gas Corporation (ONGC.NS) shares gained 1.8 percent, while Oil India (OILI.NS) rose 2 percent.
Reliance Industries Ltd (RELI.NS) rose 0.13 percent, gaining less than its peers after the market regulator rejected its request to settle a long-pending dispute over the 2007 sale of stock futures in a unit.

IFCI (IFCI.NS) shares gained 11.4 percent after the government restructured the board of the project finance provider according to a stock filing, sparking hopes of a turnaround in operations.
However, Tata Steel (TISC.NS) ended 1.9 percent lower while Jindal Steel and Power (JNSP.NS) fell 1.8 percent on profit taking, after gaining on the back of a rise in international metal prices after the end of the US "fiscal cliff" issue.
