Fortunately, many business are recognizing a fifth and a more
important source, commodities. Without commodities, business can
become risky at any point in time. These commodities can range from
inventory, to natural commodities like diamonds and gold.

Your question would be, why choose natural commodities like gold?
There are many reasons: Unlike many commodities, there prices are not
affected nor related by all the other assets (for example, inventory
is directly related to the business type). Gold is much more stable
in any economy and would do good for any company or even personal
savings for your future. Independent studies have shown that while
alternative assets and traditional diversifiers often fail during
times of market stress or instability, even a small allocation to
gold may significantly improve the consistency of portfolio
performance during both stable and unstable financial periods.
