不要只看利润率有多高,更要看利润率的稳定性。高利润率如果建立在不稳定的竞争优势上,就是一座即将倾倒的塔。真正的好公司能在一个完整的商业周期中维持高利润率。
Don't just look at how high the profit margin is — look at its stability. A high margin built on unstable competitive advantages is a tower about to fall. Truly great companies maintain high margins across a full business cycle.
