Do you invest in what you don't understand?

Principles of value investing have helped create legends of the likes of Warren Buffett and Peter Lynch. The principles are simple and easy to understand. Pick a sound business that is available at cheap valuations. And then hold it till such time the value is realized.

But the most important principle is to invest only in what you understand. This means to stay within your own circle of competence. As Buffett puts it "Everybody's got a different circle of competence. The important thing is not how big the circle is. The important thing is staying inside the circle." As simple as it sounds, it is the most difficult principle to follow. And wandering away from it can cause investors the biggest harm.

A case in point for this is that of the emerging market guru, Mark Mobius. While Mobius has enjoyed tremendous success with his investment techniques in Asia, his emerging market fund has not done so well outside of the region. In fact, the geographically diverse Emerging Market Fund has ranked only 103 out of 236 funds over 10 years in total returns.

So does it mean that Mobius has changed his style of investing? No he has not. He still sticks to his principles of picking value buys. However, it may be possible that he has just stepped outside his circle of competence.

Do you stick to your own circle of competence while choosing your investments?
