Alternative investments refer to investments outside stock, bond, and property.
Gold investment is one example of alternative investments.
It is a good hedge against the devaluing of US dollar, and against inflation.
However, you do not expect gold to produce income.
You gain a net profit upon selling the gold bar at a higher price.
Most alternative investments do not produce income.
Some of the exotic alternative investments include art investing, fine wine investing, oil exploration, numismatic coins and forex trading.
You need to have expert knowledge or expert guidance in order to succeed in alternative investments.
