Bull and Bear Market Strategy
Value investing has no bull or bear markets—only cheap and not cheap.
📌 Concept Analysis
Bull and bear market strategy = Value investors fundamentally don’t need to judge whether it’s a bull or bear market; they only need to judge whether a company is cheap.
When you go to the vegetable market, you don’t not buy just because “it’s peak season today,” nor do you buy extra just because “it’s off-season today”—you only look at quality and price. Value investing follows this same logic: Mr. Market quotes every day; you only need to determine whether this price is reasonable, which has nothing to do with whether the market is “bull” or “bear.”
💡 Core Understanding
1. The very notion of bull and bear markets reflects speculative thinking, not value investing language.
Duan Yongping believes that once you start thinking “is this currently a bull or bear market?” your starting point has already shifted. Value investors focus on a company’s intrinsic value, not the direction of market sentiment. Mr. Market’s emotions are unpredictable; bull/bear market judgments are all hindsight.
2. Bull and bear market talk is all hindsight—no one can predict in advance.
This means all strategies based on bull/bear judgments are essentially gambling on probabilities, not investing.
3. During “bear markets,” margin of safety appears with higher probability—but this is a result, not a strategy.
Value investors like bear markets not because they identified a bear market but because there are more bargains during bear markets.
4. At any time, your strategy should be the same: find cheap good companies, buy and hold.
Doing the right thing doesn’t change based on market environment; this is the same thing as long-termism.
🛠 How to Practice
Don’t ask “Is this a bull or bear market?” Ask “Is this company cheap now?”
- Ignore market sentiment labels: When media start discussing extensively whether “a bull market has arrived” or we’re in “bear market phase 3,” these judgments provide no help for your investment decisions. All you need to do is check companies you follow—are prices reasonable?
- Bear markets are opportunities—but not because it’s “a bear market”: When the market crashes sharply, good companies often fall too, meaning margin of safety appears with higher probability. But your reason for buying should be “this company got cheaper,” not “the bear market is here so I should buy.”
- Ordinary Mind is the best bull/bear strategy:** Don’t get excited in bull markets, don’t panic in bear markets. Buying logic and selling logic should both be based on the company itself, not market sentiment.
❓ Selected Q&A
Q: Does value investing consider bull and bear markets? Are bull and bear markets knowable? Can they be judged?
A: Just look at the definitions. A so-called “bull market” (or bullish market) refers to a generally rising market with sustained upward movement over an extended period. A so-called “bear market” (or bearish market) refers to generally pessimistic conditions with sustained decline over a relatively extended period. Bull and bear market terminology is all hindsight—no one can predict it, or rather half the people can predict it, but beforehand nobody knows which half is right. Value investing only considers whether something is cheap, not others’ opinions, so it shouldn’t factor this in.

Q: People who discuss “investment strategies for bull and bear markets” inevitably have some speculative mindset, wouldn’t you say?
A: It should be called “to some degree” though even using that phrase may not be quite appropriate here. Thinking about bull and bear markets IS speculation—it’s not a matter of degree.

Q: Bull and bear markets are just the market’s views. What’s most important in investing?
A: Bull and bear markets are just the market’s views. What matters most—and indeed the only thing—in investing is understanding the company’s future. If you can’t understand it, sit on the sidelines. Betting on bull or bear markets is dangerous. If you’re buying a non-public company, what does it matter how many points the stock market is at?

⚠️ Common Misconceptions
-
❌ “The bear market is here—I should go all-in” — Correct view: Your reason for buying should be “this company has gotten cheaper,” not “the bear market is here.” “Going all-in when companies you understand and like become cheap is usually correct—it has nothing to do with bull or bear markets, even though it might seem somewhat related.” (Source: Investment Logic, 2012-07-08)
-
❌ “The bull market is here—I should reduce positions” — Correct view: Triggers for selling logic are changes in company fundamentals or severe overvaluation, not “the bull market is here.” “I’ve never seen anyone running a business who sells during bull markets and buys back during bear markets!” (Source: Investment Logic, 2015-06-28)
-
❌ “85% of people lose money in both bull and bear markets, proving the market is unpredictable” — Correct view: The root cause of losses is “buying things you don’t understand,” not unpredictability of the market. “Buying what you don’t understand is why 85% of people can lose money in both bull and bear markets.” (Source: Investment Logic)

“Right business, right people, right price have no necessary relationship with bull or bear markets, but ‘right price’ does appear with much higher probability during ‘bear markets’ than during ‘bull markets.’ However, when right price appears, buyers don’t need to know whether it’s currently ‘bull’ or ‘bear.‘” (Source: Duan Yongping Investment Q&A (Investment Logic), 2012-07-08)
“Shouldn’t it always be the same?! At any time, doing the right thing must come first. For investing, if you can’t figure out where a company will be in 5-10 years, best not to touch it.” (Source: Duan Yongping Investment Q&A (Investment Logic), 2015-06-27)
“Personally, I think the terms ‘bull market’ and ‘bear market’ aren’t value investing concepts. In fact, nobody really knows when it’s a bull market and when it’s a bear market (plenty of people know afterward), and most people lose money in both bull and bear markets.” (Source: Duan Yongping Investment Q&A (Investment Logic), 2010-12-06)

牛市熊市策略
价值投资没有牛熊市，只有便宜与不便宜
📌 概念解析
牛市熊市策略 = 价值投资者根本不需要判断牛熊，只需要判断公司是否便宜。
你去菜市场买菜，不会因为”今天是旺季”就不买，也不会因为”今天是淡季”就多买——你只看菜的质量和价格。价值投资就是这个逻辑：市场先生每天报价，你只需要判断这个价格是否合理，和市场是”牛”还是”熊”没有关系。
💡 核心理解
1. 牛熊市的说法本身就是投机思维，不是价值投资的语言。
——段永平认为，一旦你开始思考”现在是牛市还是熊市”，你的出发点就已经偏了。价值投资者关注的是公司的内在价值，而不是市场情绪的方向。市场先生的情绪是不可预测的，牛熊市的判断都是马后炮。
2. 牛熊市的说法都是马后炮，没有人能事先预测。
——这意味着所有基于牛熊判断的策略，本质上都是在赌概率，而不是在做投资。
3. “熊市”时安全边际出现的概率更高，但这是结果，不是策略。
——价值投资者喜欢熊市，不是因为他们判断出了熊市，而是因为熊市时便宜货更多。
4. 任何时候，策略都应该是一样的：找到便宜的好公司，买入并持有。
🛠 如何实践
不要问”现在是牛市还是熊市”，要问”这家公司现在便宜吗？”
- 忽略市场情绪标签：当媒体开始大量讨论”牛市来了”或”熊市第三期”时，这些判断对你的投资决策没有任何帮助。你需要做的只是检查你关注的公司，价格是否合理。
- 熊市是机会，但不是因为”熊市”：市场大跌时，好公司往往也跟着跌，这时候安全边际出现的概率更高。但你买入的理由应该是”这家公司便宜了”，而不是”熊市来了该买了”。
- 平常心是最好的牛熊市策略：不因牛市兴奋，不因熊市恐慌。买入逻辑和卖出逻辑都应该基于公司本身，而不是市场情绪。
❓ 精选问答
问：价值投资会考量牛市与熊市吗？牛熊市是可知的吗？能判断吗？
答：看看牛市熊市的定义就知道了。所谓”牛市”，也称多头市场，指市场行情普遍看涨，延续时间较长的大升市。所谓”熊市”，也称空头市场，指行情普遍看淡，延续时间相对较长的大跌市。牛熊市的说法都是马后炮的说法，没人可以预测，或者说只有一半的人可以预测，但事先没人知道是哪一半对。价值投资只管便宜与否，不管别人的想法，所以应该不考量。

问：讲”牛市以及熊市的投资策略”的人不多不少都有一些投机的心态吧。
答：应该叫”或多或少”不过，这里用或多或少可能也不太合适。想着牛熊市本身就是投机，不是或多或少的问题。

问：牛市熊市都是市场的看法，投资最重要的是什么？
答：牛市熊市都是市场的看法，投资最重要其实也是唯一重要的是看懂公司的未来。看不懂就歇着，赌牛市或熊市是危险滴。如果买的是非上市公司，股市多少点有啥关系？

⚠️ 常见误区
-
❌ “熊市来了，该满仓买入了” — 正解：买入的理由应该是”这家公司便宜了”，而不是”熊市来了”。“在自己了解并喜欢的公司便宜的时候满仓往往都是对的，和熊市牛市无关，虽然看起来好像有点相关度。“（来源：投资逻辑篇，2012-07-08）
-
❌ “牛市来了，要减仓了” — 正解：卖出逻辑的触发条件是公司基本面变化或价格严重高估，而不是”牛市来了”。“我没见过经营企业还分牛市卖掉，熊市买回的！“（来源：投资逻辑篇，2015-06-28）
-
❌ “85%的人在牛市熊市都亏钱，说明市场不可预测” — 正解：亏钱的根本原因是”买自己不懂的东西”，而不是市场不可预测。“买自己不懂的东西是为什么85%的人可以在牛市熊市都亏钱的原因。“（来源：投资逻辑篇）
