A mutual fund is an investment based fund that pools money from various investors to buy securities. It is professionally managed and provides the investor more diversification and liquidity. It continues to be one of the more popular tools of investment for those who want to beat the market or for those who are looking for a wide range of investments instead of buying stocks and shares. Mutual funds trade once every day as opposed to stocks.

The U.S. News Mutual Fund Score has one of the best methodologies to rate mutual funds, their track records and to predict where a mutual fund might head in the future. They have profiled around 100 of the largest funds with inputs from a range of experts. These include fund managers, analysts, data investors and newsletter writers.

Mutual fund investments have a downside too. They are expensive, tax inefficient and outdated. Despite this, they are still popular. Forbes gives a list of the ten best mutual funds with their pros and cons to draw from. The largest is Pimco Total Return (PTTAX) which has a long-term track record with extensive experience but which is expensive with a long duration portfolio.

The question to be answered is if mutual funds are worth your money. Going by the $16 trillion invested in them nationwide, they are.
