Refiners Bharat Petroleum Corp. and Hindustan Petroleum Corp. surged to records after their profits beat estimates. Larsen & Toubro Ltd. was the top performer this week after it forecast sales to rise this year.

Monsoon Outlook

Company earnings are recovering after falling in four of the last five quarters, which was the worst run since the financial crisis.

That’s more than the quantum forecast by the state weather office and would be the highest since 1994.

Bad-Loan Ratio

“SBI’s gross NPA ratio was much lower than its peers,” Purvesh Shelatkar, senior vice president and head of equities at BOB Capital Markets Ltd., said by phone from Mumbai. “Some investors were expecting the ratio to widen as much as the bank’s peers. They were forced to cover their short positions” after earnings were announced, he said.
