* BSE index gains 0.14 pct; NSE index 0.08 pct higher
* Underperformers recover some lost ground
* Metal stocks continue to fall (Updates with consumer price inflation data)
By Indulal PM
MUMBAI, March 12 Indian shares edged higher on Wednesday, to post their sixth gain in seven sessions as drugmakers such as Sun Pharmaceutical and software services exporters such as Tata Consultancy Services recovered from recent steep losses.
Gains could accelerate after data late in the day showed consumer price inflation slowed more than expected to a 25-month low of 8.1 percent in February, helped by moderating food prices.
The sharp ease in retail prices should cement expectations the Reserve Bank of India would keep interest rates steady at its policy review on April 1 after aggressively tightening monetary policy from September to January.
"We have been seeing buying interest from overseas investors and supply is still in the market," said Suresh Parmar, head, institutional equities at KJMC Capital Markets.
"However, one should be careful in picking stocks," he added. "There are enough buying opportunities and at the same time we may see further selling pressure in metals and iron ore stocks."
The broader NSE index rose 0.08 percent, or 5 points, to end at 6,516.90, hovering near an all-time high of 6,562.85 hit on Tuesday.
The benchmark BSE index edged up 0.14 percent, or 29.80 points, to end at 21,856.22, not too far from a record high of 22,023.98 hit on Monday.
Foreign investors bought Indian shares worth 14.71 billion rupees ($241.5 million) on Tuesday, their 17th buying over the previous 18 sessions for a total of over $1.8 billion.
Exchange data shows foreign investors were net sellers on Monday, although traders say that the day was impacted as investors tendered shares as part of GlaxoSmithKline's open offer to increase its stake in the domestic unit to 75 percent from 64 billion rupees.
Among the top gainers on Wednesday were recent under-performers.
Sun Pharmaceutical Industries gained 4.14 percent, its biggest single day gain since Oct. 9, 2013, after slumping 7 percent over the previous four sessions.
Dr Reddy's Laboratories rose 0.33 percent.
Technology stocks, which went from top performers last year to struggling in recent weeks as the rupee recovered, were other strong gainers on Wednesday.
Tata Consultancy Services added 1.29 percent, but it is still down 4.3 percent for the month, compared with a 3.8 percent gain in the NSE index so far in March.
Wipro closed 1.23 percent higher.
But investors also continued to book profits in other recent gainers.
Shares in Oil and Natural Gas Corp fell 1.9 percent on profit-taking after gaining 8.8 percent so far this month.
Metal stocks continued to witness selling pressure for the third consecutive day with Tata steel losing 1.21 percent on continued concerns about China's growth prospects.
