(MONEY Magazine) - Welcome to MONEY's annual report on the year's most important funds. The 725 stock funds have combined assets in excess of $3.7 trillion and hold 87% of all the wealth in stock funds. The 275 bond entries, with $846 billion, represent 71% of bond fund dollars. To see how the funds you own--or those you are considering--fared, read on.

The Year in Review

By mid-December, stock funds had returned an average 9.4% for 2005. (Not bad, considering the five-year annual average is 3.5%.) But fund returns varied wildly, just as market results did: The S&P 500 rose by 4.9%, just half the 9.9% gain posted by international stocks. The year's big fund winners have rising oil prices to thank: Natural-resources and emerging markets funds were up 46% and 30%, respectively, and dominate the lists of top-performing stock funds on page 90. Fixed income, meanwhile, didn't fare as well. Amid continued interest-rate increases and stagnant long-term yields, the average bond fund earned only 1.7% through Dec. 15.

On the pages that follow, you'll find returns and other key information for 1,000 of the biggest stock and bond funds, a list that also includes all of the MONEY 65 actively managed and index funds. Having trouble locating a fund? Some have merged; others may simply have changed their names. Check with your fund company.
