Investing in Precious Metals

Gold is often thought of as the ultimate safe haven. Investors view gold as a hedge against inflation and a tangible asset for a diversified portfolio.

Although buying gold and silver is still popular, two other precious metals are popular investments these days as well.


Platinum is a relative newcomer to the international precious metal trading market. Europeans first discovered platinum in South America in the early eighteenth century.

Platinum is silvery-white and is often used in high-end jewelry pieces. Its main use is for catalytic converters for automobiles. It's also used in the chemical industry.


It's rare to find palladium in nature, but it can be extracted from other metals, such as copper, platinum, and zinc.

It's popular for commercial use and has many of the same industrial uses as platinum. Palladium is a useful component in dental, medical, and electronic equipment.

Ways to Invest in Precious Metals

There are many ways to buy precious metals besides buying them by the troy ounce and storing them at home. Some modern ways to invest in precious metals include:

Commodity Exchange-Traded Funds (ETFs)

ETFs and mutual funds make it easy to invest in precious metals. You don't take possession of the metals you own through the fund, but you can buy and sell them.

Common Stock Shares

Purchasing common stock shares of metals and mining companies is a direct way to gain a stake in the precious metals market. This type of investing carries some risk since you're betting on a company successfully locating and mining precious metals.

Futures and Options Market

The Internet has opened up the futures and options market for investors. However, these markets are dominated by institutional investors and professional traders.

Gold Certificates

Gold certificates were once a form of usable currency. You can still buy them from some investment companies and banks.

They are considered portable gold equivalents but are no longer backed by the government. Instead, they are backed by the company you purchase them from and carry some risk.
