Precious metals and fixed-income investments wouldn't seem to have much in common. But they were the only classifications of closed-end funds to achieve positive returns during the first quarter of the year.

Of nine closed-end fund investment objectives tracked by TheStreet.com Ratings that prefaced their respective first-quarter performance numbers with plus signs, eight were fixed-income categories. However, as can be seen in the accompanying table, the winning classification was precious metals, with an average total return of 6.89% for the quarter.

The top precious metals closed-end fund for the quarter,

, invests almost totally in gold and silver bullion. Its shares returned 16.9% for the three months and 33.96% for the latest 12 months. A strengthening Canadian dollar wasn't really needed to help the fund finish the quarter priced at a 5.01% premium over its net asset value per share.

The steady decline of the U.S. dollar helped propel the emerging-market income and the global-income sectors to positive territory during the difficult quarter. However, closed-end funds in the solid government bond category averaged a gain of 4.00% for the period, making it the second best investment objective and the top fixed-income classification.

Not every fixed-income investment objective ended in positive territory. Investment-grade corporate bond funds eased 1.83% on average, while multi-sector bond funds slid 8.23%. The weak economy drove the average high-yield corporate bond fund down 3.11%, while the load participation category, burdened with mortgage-related problems, tumbled 9.62%.

Ironically, however, the credit crunch didn't hold back the average general mortgage closed-end fund, which ended the quarter ahead by 1.79%.

Following a torrid love affair in recent years with international funds, especially of the emerging market genus, investors turned a cold shoulder to the overseas sectors in recent months. That left the non-U.S. equity and emerging markets equity groupings with setbacks for the quarter averaging in the double digits.

After precious metals, the next best equity category was another commodity-related area -- energy/natural resources. Even though one of its component funds --
