World's Top 10 Hedge Funds

Hedge funds are alternative investments that use various methods such as leveraged derivatives, short-selling, and other speculative strategies to earn a return that outperforms the broader market. Hedge funds invest in domestic and international markets alike. They typically impose investment minimums of hundreds of thousands of dollars to millions of dollars and target high-net-worth individuals, pension funds, and institutional investors.

As a result, hedge funds invariably carry higher risks than traditional investments. They are not subject to the same regulations as mutual funds and may not be required to file reports with the U.S. Securities and Exchange Commission (SEC).

The Bottom Line

Hedge funds seek to employ unique strategies with the goal of providing greater returns than the market or standard investment strategies. Hedge funds come up with unique ideas to employ in the markets and charge a high price for doing so.

They're not created for the average investor but rather geared toward institutions and high-net-worth individuals, as many hedge funds come with minimum investment amounts, which can often be in the millions. As such, these firms command billions of trading assets.
