Some people are concerned about stocks whose earnings have been rising. Some people look at consumer goods, some look at bankrupt companies, and some look at bad debts. This is investment. But they are always looking for value above cost, which is the most basic principle of investment that will never go out of fashion.
有些人关注收益一直在上升的股票，有些人看消费品，有些看破产公司，有些看不良债务，这就是投资。但他们总是在寻找高于成本的价值，这就是投资里永远不会过时的最基本原则。
