For personal finances, buying gold looks like an extremely foolish idea to me, but, I admit, I am not a financial adviser.
First off, don’t think of gold as a commodity. Think of it as just another foreign currency, That’s what most of the world does. If you do that you might consider buying, say, Swiss common stocks. Such stocks would serve the same inflation hedge against the US dollar as gold and are better to own, IMO.
Second, gold does not pay dividends or interest. In fact, storing it can cost the investor.
Historically, it just does not compare well to common stocks.
Investing in solid, boring, companies like MMM, PG, or JNJ would have made you 50 or a 100 times more over the last 35+ years.
MMM: The adjusted closing price Feb 28, 1980 was $2.59. Price Feb 27, 2015 was $168.65.
JNJ: The adjusted closing price Feb 28, 1980 was $0.67. Price Feb 27, 2015 was $102.51.
PG: The adjusted closing price Feb 28, 1980 was $0.86. Price Feb 27, 2015 was $85.13.
Those increases ignore the very substantial benefits of dividends for those stocks. MMM paid $3.42 / share in 2014. JNJ paid $2.64, and P&G paid $2.57. Gold paid zero, nada, ziltch. And if you stored it somewhere safe, you had to pay extra for that too.
Gold was left in the dust by those stodgy stocks. From Feb 28, 1980 to today gold is only up about 3X. Gold finished Feb 27 at 1,213.70.
And those aren’t sexy stocks, they’re steady, good companies, but they’re not Apple.
I’m not saying to avoid gold. I am saying keep it to a minimum. Maybe buy some nice pretty gold coins from the US Mint, if you must.
