l have a mutual fund that l opened through washington mutual. After hearing that washington mutual has been bought out, l wanna know if my mutual fund is safe and protected?

Yes, it is protected. You may have some inconveniences getting to it right now, but the shares are yours, not WaMus.

Those shares r protected by the SIPC to insure ur ownership. The Mutual Fund will continue to be run as before.
How the Mutual Fund performs has NOTHING to do with the takeover of WAMU.
Give it a few days. Next week, contact the representative for advise or instructions. Companies such as Fidelity Investments, Charles Schwab & others will be happy to help u transfer ur mutual fund shares to their care if u r worried.
It will take quite some time before the new management makes any changes.

Yep, nothign to worry about, maybe the hassle of getting your money.
