Operations not meeting these requirements are speculative.” - Benjamin Graham
我们不难理解,在 Nortel 的整个历史中,没有任何一个时刻存在合理的投资机会和理由,你只能用纯粹的投机方式参与其中。绝大的多数人会抵制不住或主动喜欢这类的市场诱惑,但它不会发生在成熟的投资者身上。
To be a successful investor, you have to have a philosophy and process you believe in and can stick to, even under pressure. Since no approach will allow you to profit from all types of opportunities or in all environments, you have to be willing to not participate in everything that goes up, only the things that fit your approach. To be a disciplined investor, you have to be able to stand by and watch as other people make money in things you passed on. - The truth about investing.

投资并不需要完美,也不可能完美。在投资中有失败是一种常态。

我们假设2000在Nortel, 黑莓和TD各投入1万,今天将Nortel和黑莓清零,TD的市值是7万多,所以在33%的成功概率下,也还是处于赢利状态的。我们能够承受投资中不可避免的失败部分。
The average P/E ratio for Japanese stocks in 1989 was about 70.
说实话,我不太明白为什么要去讨论一个PE值70的市场,没有任何意义。
1998年可口可乐PE值95,之后发生的一切仅仅是正常的价值回归,没有任何特别之处。
