Wasatch Funds recently decided to refuse all new money, even from existing shareholders, for four funds that had between $459 million and $1.32 billion in them apiece, Reuters reports. While funds, from time to time, close to new investors, it is unusual for a fund to shut out even existing investors. Wasatch had already disallowed new investors from investing in the four funds.

The Wasatch Core Growth fund recently had $1.32 billion of assets, the Small Cap Growth fund had $1.02 billion, and both the Micro Cap and the Ultra Growth funds had $459 million apiece.

The closure was due to the firm’s "desire to protect the interests of existing shareholders and prevent asset size from becoming a hindrance to performance," Sam Stewart, Wasatch chairman, told Reuters. The four Wasatch funds invest in small cap stocks, a smaller universe than mid-cap and large-cap stocks. As such, it is harder for such funds to handle excessive inflows and still deliver strong returns.
