Indian shares touched record highs for a third consecutive session on Wednesday, with investors picking pharma stocks such as Sun Pharmaceutical Industries Ltd that have lagged a broader market rally this year.
The gains tracked Asian shares, which edged higher as a rally in commodities to multi-year peaks pushed resources-linked stocks up.
"Global liquidity and lack of other attractive investment options are supporting the current global equity rally. Pharma and IT stocks are available at attractive valuations, so some steam is visible there," said Sumit Pokharna, deputy vice president at Kotak Securities.
