But this does not mean that gold is always a great investment. In fact, when I was a young man in January of 1980 gold reached an historical high point of 850$ while at the same time the Dow Jones Industrial Average was indexed at 825.
Today, gold's price is 1730$, but adjusting for inflation, it would need to be 2363$ for it to have yielded a "zero percent return" over the past 32 years. Indeed, had you bought gold in 1980, you have received a negative return on your investment.
During the same period, the Dow has risen to 13322 and needed only to reach 2294 to yield an inflation-adjusted zero-percent return. In fact, it is 5.8 times larger than that and so has yielded a real, inflation-adjusted return of 480% over the 32 year period in question.
