1. Invest In What You Know

This is where it helps to have identified your personal investor’s edge.  What is it that you know a lot about?  Maybe your edge comes from your profession or a hobby.  Maybe it comes just from being a parent.  An entire generation of Americans grew up on Gerber’s baby food, and Gerber’s stock was a 100-bagger.  If you put your money where your baby’s mouth was, you turned $10,000 into $1 million.

2. Let Your Winners Run

It’s easy to make a mistake and do the opposite, pulling out the flowers and watering the weeds.  If you’re lucky enough to have one golden egg in your portfolio, it may not matter if you have a couple of rotten ones in there with it.  Let’s say you have a portfolio of six stocks.  Two of them are average, two of them are below average, and one is a real loser.  But you also have one stellar performer.  Your Coca-Cola, your Gillette.  A stock that reminds you why you invested in the first place.  In other words, you don’t have to be right all the time to do well in stocks.  If you find one great growth company and own it long enough to let the profits run, the gains should more than offset mediocre results from other stocks in your portfolio.

3. On Growth Stocks

There are two ways investors can fake themselves out of the big returns that come from great growth companies.  The first is waiting to buy the stock when it looks cheap.  Throughout its 27-year rise from a split-adjusted 1.6 cents to $23, Walmart never looked cheap compared with the overall market.  Its price-to-earnings ratio rarely dropped below 20, but Walmart’s earnings were growing at 25 to 30 percent a year.  A key point to remember is that a p/e of 20 is not too much to pay for a company that’s growing at 25 percent.  Any business that an manage to keep up a 20 to 25 percent growth rate for 20 years will reward shareholders with a massive return even if the stock market overall is lower after 20 years.
The second mistake is underestimating how long a great growth company can keep up the pace.  In the 1970s I got interested in McDonald’s.  A chorus of colleagues said golden arches were everywhere and McDonald’s had seen its best days.  I checked for myself and found that even in California, where McDonald’s originated, there were fewer McDonald’s outlets than there were branches of the Bank of America.  McDonald’s has been a 50-bagger since.
