Mumbai: ICICI Prudential Mutual Fund will not accept lump sum money in its mid- and small-cap schemes from March 14, deploying flow curbs a day after Sebi chairperson Madhabi Puri Buch underscored the dangers of potential "froth" or "bubbles" in pockets of the market traditionally favoured by retail investors.

Earlier, Nippon, Tata and SBI MFs put restrictions on lump sum investments in their small-cap schemes, as high valuations and strong flows make it challenging for fund managers to deploy money. But ICICI will be the first fund house to restrict lump sum investments in a mid-cap fund.
