I limit second-line stocks to less than 20 percent of my portfolio. Having been around in the markets for more than a decade, I have seen plenty of rising stars vanish without a trace. The returns from tried-and-tested frontline stocks may not be spectacular, but over longer periods of time, they tend to be more consistent and reliable. The key to a lifetime of investment success is not to make brilliant or complex decisions but to avoid doing foolish things.
