Vivek Iyer, Partner and CIO at Rational Asset Management, expects bears to intensify their selling in midcap, smallcap and microcap stocks. "And last week's fall is the start, not the end," he said in an interview with Moneycontrol. Brent is now at $117 per barrel, and the mid- and small-cap universe is where the input cost lands first. Hence, "the selling continues until the estimates come down and the multiples meet them, and that does not happen in a week," he said.
