投资者唯一最大的优势就是长期视角。如果你的时间框架是三年而不是三个月，你就已经击败了市场上90%的参与者。

价值投资的本质是逆向思维与计算器的结合。用计算器算清楚值多少钱，用逆向思维在别人恐惧时扣动扳机——两者缺一不可。

大多数投资者主要关注回报——我能赚多少——而很少关注风险——我会亏多少。但风险控制才是在市场中长期存活的前提。没有存活，一切回报都是空谈。

最好的投资机会往往出现在投资项目看起来最糟糕的时候。当所有人都说'这个没法看了'，也许就是你应该认真看一看的时候了。

等待'胖球'（好打的球）是投资成功的关键之一。你不是在打板球——没有三振出局的规则。你可以无限期地等待，直到最好的机会出现。

价值投资的核心是以低于内在价值的价格买入资产。

The core of value investing is buying assets at prices below their intrinsic value.

买得便宜是安全边际的来源。

Buying at a discount to intrinsic value is the source of margin of safety.

没有投资应该被视为神圣不可侵犯——当更好的机会出现时，即使要承受损失也应换仓。

No investment should be considered sacred when a better one comes along.

现金在牛市中让人焦虑，但在熊市中它就是你最好的朋友。永远不要因为持有现金而感到不安——知道何时出手比时刻满仓重要得多。现金就是干火药。

Cash is anxiety-inducing in a bull market, but in a bear market it's your best friend. Never feel uneasy about holding cash — knowing when to strike is far more important than being always fully invested. Cash is dry powder.

自下而上的投资者不从宏观预测开始。他们从一家一家公司的分析开始——先确定这家公司在这个价格下值不值得买，然后再看宏观环境是否构成重大风险。

Bottom-up investors don't start with macro forecasts. They start with company-by-company analysis — first determine if this company at this price is a buy, then check if the macro environment poses a major risk.

安全边际不是一个抽象概念，而是一道具体的数学题。你买一家公司花了100块，你算出来它值150块——那50块的差距就是你的安全边际。这个差距越大，你需要正确的概率就越低。

Margin of safety isn't an abstract concept — it's a concrete math problem. You buy a company for $100, and you calculate it's worth $150 — that $50 gap is your margin of safety. The bigger the gap, the lower the probability you need to be right.

知道何时卖出和知道何时买入同样重要。最简单的卖出规则是：当股价超过了你对内在价值的估计时卖出。不是因为它涨了，而是因为安全边际消失了。

Knowing when to sell is as important as knowing when to buy. The simplest selling rule is: sell when the price exceeds your estimate of intrinsic value. Not because it went up, but because the margin of safety has disappeared.

华尔街的研究报告不是你投资的起点，而是你形成独立观点之后用来核对的参考。永远先做自己的功课，再看别人怎么想。顺序不能颠倒。

Wall Street research reports are not the starting point of your investment — they're a reference to check after you've formed your own independent view. Always do your own homework first, then see what others think. The order cannot be reversed.
