The broader NSE Nifty on Thursday hit its highest in nearly two years and moved close to breaching a key psychological level of 9,000 on continued hopes about the domestic economy after auto manufacturers reported higher sales.
Sentiment was also boosted as Asian stocks inched to a 19-month high, a day after Wall Street hit record highs as investors were encouraged by President Donald Trump's less-combative tone in his first speech to Congress.
The global rally is coming at a time of growing hopes about India's own economy. Data on Tuesday showed annual gross domestic product (GDP) in the October-December quarter was much stronger than expected, cheering market sentiment despite widespread scepticism by economists.
Auto shares such as Tata Motors Ltd gained after reporting higher monthly sales, further
raising hopes about the economy.
"There is a positive underlining sentiment in the Indian market," said Tirthankar Patnaik, India strategist, Mizuho Bank.
