The Best Investment Advice From Alan Greenspan

Alan Greenspan isn't the first name that comes to mind when you think of great investors. But the longtime Fed chairman is certainly one of the greatest minds in history when it comes to economics. He's the guy that coined the term "irrational exuberance," after all.

While Greenspan might not have the investment track record of a Warren Buffett or Philip Fisher, it's worth paying attention to what he says about the stock market. Here's the best investment advice from Alan Greenspan.

"If you did nothing else..."

Greenspan has repeated the same thing in several different ways. The basic tenet is the average investor will do better if he buys stock and never sells rather than try to time the market.

The advice is easy in theory, but much harder in practice. The "sleeping point" Greenspan references in that final quote refers to the point at which individual investors start to lose sleep over their portfolios and decide to sell everything. Individuals that can endure that pain and fear will come out well ahead of the average investor.

You can spot a bubble

Many investors are afraid we're in the midst of yet another economic bubble brought on by low interest rates following the fallout of the 2008 financial crisis. They might be right, but knowing we're in a bubble is the easy part.

If you can take Greenspan's first piece of advice, you don't even need to concern yourself with what he says here. But the fact that calling the top of a bubble is necessarily impossible should give you yet another reason not to try to time the market.

Get rid of your home bias

Investors have a natural tendency to favor companies from their home country or some familiar environment. Don't let this prevent you from geographic diversification.

Diversifying a portfolio beyond your home country ensures that your entire portfolio isn't subject to underlying economic factors of just one nation. Of course, many U.S. companies have become global entities operating all over the world. These big multinational corporations can provide significant exposure to other markets, and should be considered when diversifying with foreign investments.

Following the advice of Alan Greenspan can help you outperform the average investor. Buy stocks and hold them forever, don't try to time the market, and properly diversify geographically by overcoming your home bias, and you'll surely do well with your investments.
