There are at least 3 ways.. 1. buy GLD. It is an index fund indexed to the price of gold. It trades like a stock less expenses.. . 2. buy shares in a gold mining company such as ABX or several dozen others that are available. . . 3. buy options in shares of a gold mining company. That gives you your greatest leverage and also your greatest risk. . . 4. you can also get leverage by buying shares in a marginal gold mining company--one that is marginally profitable. An increase in the price of gold means a big increase in their profits. ABX is probably the most profitable gold mining company so it gives you the least leverage, but is a relatively safe investment.
