Tax-Free Money-Market Funds Shine

The best rated open-end bond funds in May were tax-free money market funds paying out a consistent stream of income. Four municipal funds also made the top-10 list.

With stocks flirting near bear-market territory, off as much as 20% for the Dow Jones Industrial Average since October, investors may be seeking the relative safety of the bond market.

Unfortunately, the weak economy and inflationary environment has firms such as Lehman Brothers(LEH), Bank of America(BAC) and Barclays Capital(BCS) predicting another corporate bond slump warning investors to pare their holdings.

The best rated open-end bond fund this month is the Evergreen Institutional U.S. Government Money Market Fund(EGNXX), rated A+.

This fund, with $1.8 billion in assets, sticks to U.S. government securities with the goals of capital preservation and liquidity management. If Federal Reserve Chairman Ben Bernanke proves powerless to restrain inflation, the meager return from this fund may not be enough to overcome the loss in purchasing power over time.

The A+ rated US Global Investors US Government Securities Savings Fund(UGSXX) is in the same boat. This fund's objective is high current income consistent with the highest possible safety of principal and liquidity. The fund may be smaller in total assets at $455 million but has been in business since 1986.

The highest rated of the four municipal bond funds on our list is the Advantage Ultra Short-Term Municipal Income Fund(SMUAX) offered by Wells Fargo(WFC). This A+ fund targets federal tax-exempt income while allowing a small amount of share price fluctuation.

The top holding, at 7.1% of assets, is the Golden State Tobacco Securitization Corp./CA. This should not be confused with the Garden State's Tobacco Settlement Financing Corp./NJ, which is the second largest holding at 4.1% of assets.
