The main problems with gold bullion are that the storage and insurance costs, and the relatively large markup from the dealer both hinder profit potential. Also, buying gold bullion is a direct investment in gold's value, and each dollar change in the price of gold will proportionally change the value of one's holdings. Other gold investments, such as mutual funds, may be made in smaller dollar amounts than bullion, and also may not have as much direct price exposure as bullion does.
Despite headwinds related to the likelihood of additional interest rate hikes, gold may be poised to deliver solid returns again during the fourth quarter of 2018. The precious metal has traditionally been perceived as a safe haven investment in times of economic uncertainty and the recent concerns – along with the slide in stock prices – certainly fit the bill.
