The concept of economic moats was first made popular by Warren Buffett. In actuality, a moat is a water body around a wonderful castle that helps prevent being raided by enemies. The attractiveness of the castle would have lured enemies to attack. In a similar way, the superior returns of a business venture would invariably attract competition. To protect your business you would have to build significant competitive advantages that would help secure it. Branding Superior product offering Great distribution Size of operation Scalability Management quality Technology adoption IPR / patents / copyrights are some of the factors which help to build a moat. And several of these together help to broaden and deepen the moat. Businesses without moats are waiting to get raided. And we must watch the economic moats with a hawks eye to ensure that they are not being eroded. Especially in today’s times, when disruptive forces erode competitive advantages, we must ensure that it is enduring. However, it is not easy to understand whether the moat is eroding or not. Cause the effect of no moat or an eroding moat will show up much later in the deteriorating financial performance of the business. Hence the time to engage in a “moat checkup and review” is when the business is at its peak.
