"Money market funds get last laugh" says The Contra Costa Times. "Money market funds are nothing more than mutual funds that invest in short-term corporate debt or notes. Assuming that you have a true money market fund, there is essentially no risk. Shares always sell for $1.00 each and the rule in the industry is to never 'break the buck.' In a few unlikely cases where some securities actually lost value within a few months, the issuing investment company ponied up the difference to protect its reputation. There IS a risk for anyone who let themselves be talked into something that was represented as a money market fund, but that turned out to be something else -- like the auction-rate securities investments that have triggered lawsuits," says the article.
