Most people understand what a mutual fund is and think a hedge fund investment is the same thing. They are correct in that a hedge fund is a group of investors that pool their money, just like a mutual fund. Hedge funds, however, don't have the same type of regulation that the mutual fund has. In fact, you have to have a specific amount of wealth to invest in a hedge fund and a required amount of investment savvy. A hedge fund investment is not a public offering, but often a private limited partnership with the fund manager as the general partner.

Hedge funds do things because it is a private investment, which regular mutual funds can't do. One example is the ability to sell short. This is a risky technique especially if it's a naked short sale. The short sale is when you sell a stock in hopes of purchasing it later at a cheaper price to fill the sale.

A naked sale is one where you sell a stock you don't own. To comply with government regulations you must be able to borrow it from someone before you sell it. The reason that it's so risky is that the price could skyrocket after you sell the stock. Then you must pay huge amounts to fulfill your obligations to the buyer.

When large hedge funds use the techniques, often they drive the price down artificially in the sale of the stock and minutes later, can make a quick profit with the purchase and delivery of the cheaper stock. This is one way a hedge fund investment brings higher income than the traditional mutual fund.

The original purpose of a hedge fund was to hedge against the market's swings. The combination of different types of investments provided an equation against falling markets. The change came as hedge funds became more popular. Today, they provide not just a hedge against loss but an edge for gain.

The typical hedge fund investment contains derivatives that are high yield and debt from companies considered risks, so they have to pay more to borrow, or their loans sell at discounted rates which means the yield on the return is higher. If you use a $1,000 loan as an example, with the company loan rate at 8%, that is a decent comfortable return. Now, if that same company gets behind on the loan and the lending institution panics, they might sell it at a 50 percent reduction of the balance to the hedge fund. This in effect means that not only does the fund get 16 percent interest, but if the company actually pays the loan in full, they make a 100 percent gain on that money.

If you have plenty of money already, you may be the perfect candidate for a hedge fund investment. These types of investments are supplementary to normal investments. They attempt to defeat bear markets and bring in money while they also take advantage of the bull market and yield a higher return. There are risks in a hedge fund, ones that the average investor would never take. With the onset of a bear market, the technique of short selling is one of the best ways to hedge the bad market and take the lemon that the economy handed you and make lemonade.
