Seeking Alpha analyst Jeffrey Himelson writes that uncovering companies that have unreplicable qualities, a competitive advantage is one of the most salient tenants of successful investing. Warren Buffett uses this precept in making his investment selections. Following this principle led him to his most lucrative investments such as Coca-Cola with a 766% gain and Procter & Gamble which netted him a staggering $4.32 billion in profit. Companies that do not possess a competitive advantage are subject to an onslaught of competition which raises costs and cuts revenue growth. Pandora Media was one of the first movers into the online radio industry, but the subsequent influx of competition has muted profits.
