Long periods of seeming invincibility. Though some industries or lines of business exhibit characteristics that endow leaders with virtually insurmountable advantages, and that tend to establish Survival of the Fattest as almost a natural law, most do not. Thus, for every Inevitable, there are dozens of Impostors, companies now riding high but vulnerable to competitive attacks. Considering what it takes to be an Inevitable, Charlie and I recognize that we will never be able to come up with a Nifty Fifty or even a Twinkling Twenty. To the Inevitables in our portfolio, therefore, we add a few "Highly Probables."

在所属的产业都被赋予其无可取代的优势地位,大者恒存的自然定律似乎牢不可破,但实际结果却不然,也因此在找到真正的真命天子之前,旁边可能还有好几打假冒者,这些公司虽然曾经红极一时,但却完全经不起竞争的考验,换个角度来看,既然能够被称为永恒的持股,查理跟我早就有心理准备,其数量绝对不可能超过五十家或甚至是不到二十家,所以就我们的投资组合来说,除了几家真正够格的公司之外,还有另外几家则是属于极有可能的潜在候选人。
