"The Pharma index was the worst performer on the NSE and the BSE in trading today. Pharma stocks were spooked by the quarterly results of Taro Pharmaceuticals, which is the overseas arm of Sun Pharma.
"The reason Taro Pharma is important for pharmaceutical sector in India is that it is seen as representative of the vast Indian generics business in the US," said Sarabjit Kour Nangra, VP Research - Pharma, Angel Broking.
The BSE benchmark Sensex tumbled 206 points to end at 30,365.25.
"Pharma continued to taste bitterness in earnings due to high competition which is impacting the sentiment of the sector for the long-term," said Vinod Nair, Head of Research, Geojit Financial Services Ltd.
