Bank of America Merrill Lynch has downgraded Indian utility vehicle and tractor makerMahindra and Mahindra to 'underperform' from 'neutral', saying it expects slower earnings growth.

"We expect core business volumes to disappoint and profit to decelerate sharply, leading to street downgrades. Our FY13E EPS translates to low single profit growth and 9 percent below street, justifying non-consensus rating," the Wall Street bank said in a note on Tuesday.

It also cut its target price to 645 rupees from 815 rupees. The stock closed at 674 rupees on Monday.
