Some fund watchers are calling for fund managers to put their money where their mouth is, so to speak. Although fund managers stake their reputation and bonus on the funds they manage, critics are asserting that they should be putting their own money on the line, just like the shareholders, Reuters reports.

Many managers do, in fact "eat their own cooking," the industry term for investing in a fund one manages. Fund watchers are calling for regulation that would require the managers to state exactly how much money, if any at all, is invested in the fund.

Industry watchdog Roy Weitz told Reuters that people in position of public trust, such as fund managers, have a responsibility to disclose some personal information, such as their own holdings in a fund.

"It’s essentially the same argument we heard fund managers advancing about why CEOs should own a lot of their own company," Russel Kinnel, director of fund analysis at Morningstar, told Reuters.

A spokeswoman from Oakmark Funds said that several of their managers have gone on the record stating that their highest asset outside their home, or other real estate, is their investment in the mutual funds. Fidelity said many of its managers invest in funds they manage, although they are not formally required to do so. John Montgomery, founder of Bridgeway Funds, has gone public with the fact that his holdings total around $490,000. He also said that these investments are his only exposure to the market.
