如何区分耐心与死钱（僵尸股）？
作者寻求一个决策框架，以决定是继续持有表现不佳的股票还是重新配置资金，并以 Adobe 为例。
- 如果原始投资逻辑未被破坏且公司基本面依然稳健，则应继续持有。
- 忽略成本基础，给管理层时间去执行商业计划。
- 资金的机会成本很高；等待数年才回本可能效率低下。
- 锚定成本基础是一种认知偏差，可能导致持有死钱（僵尸股）。
我知道在这个版块提到‘S’字是禁忌，但我最近在重新评估我的投资组合，对于如何决策卖出那些大幅下跌的持仓感到纠结。
投入投资几年后，我积累了一些较小的持仓。有些下跌了20%到30%，有些甚至更多。举个例子，Adobe目前相比我的成本价已大幅下跌。这家公司并未破产，仍在产生现金流，也有合理理由认为其业务会继续存在并增长。然而，我越来越怀疑仅凭这一点是否足以支撑我继续持有。
我内心在争论的两个观点是：
阵营1： 除非最初的逻辑被打破，否则绝不卖出。忽略成本价，专注于公司基本面是否依然健康，并给管理层足够时间去执行。
阵营2： 机会成本很重要。即使逻辑未破，资金也是有限的。如果我能发现更有信心的标的，将资金调拨过去可能比等待多年反弹更合理。
这让我感到困难的是，部分持仓需要极高的涨幅才能回到当初的投资金额。与此同时，我也清楚地知道，锚定成本价是一种错误做法。
向更有经验的投资者请教几个问题：
- 你做出卖出决定的主要驱动因素是什么？
- 你是如何区分一只暂时不受欢迎的股票和一家真正恶化的企业？
- 在决定将资本转移到其他地方之前，你愿意为一个投资逻辑等待多久？
- 即使公司基本面依然健康，你是否有特定的标准会触发卖出？
- 你在多大程度上重视投资组合的简化，以及减少需要跟踪的持仓数量？
我并不特别关心Adobe本身的看法，而是更想了解你们在判断是否持有、卖出或把资金重新配置到更高信心标的时所使用的决策框架。
I would mostly stick to camp 1. You should know when you were wrong. For example i made the mistake of investing in cyclical businesses with almost unpredictable cash flows close to their peak before. When I realized my error I just sold at a loss.
Selling should come from new knowledge and not just from the stock being down in my opinion.
But it's not easy. Hence why most people fail to outperform the market (including me lol)
Both "patience" and "dead money" are labels you only assign after the fact, based on the price. You need a test that ignores the price.
The one that works for me: "Would I buy this today, at today's price, knowing what I know now?" Yes → the drawdown doesn't matter, it's patience. No → you're not being patient, you just don't want to realize the loss. That question never mentions your cost basis, which is the point.
For thesis vs deterioration: write the original thesis as falsifiable checkpoints, not vibes. Not "Adobe is a great business" but "DC net-new ARR stays above X." Then deterioration is a checkpoint failing, not a feeling. Checkpoints holding + price down = hold. Checkpoints breaking + you holding anyway = that's the cost basis talking.
Opportunity cost is real but it's the second question. "Higher conviction elsewhere" is a fine reason to trim. "It's down and I'm tired of waiting" is just the cost basis in disguise.
Thanks, this is helpful. Could you give some good examples of falsifiable checkpoints that have helped you in the decision making?
Sure. The key is they have to be specific enough that you'd know if they failed, and tied to the actual reason you bought, not generic health metrics. A few from my own holdings:
Memory/semis (I hold Micron): my thesis is the cycle plus HBM demand from AI, so my checkpoint isn't "revenue grows," it's "HBM stays sold out / capacity stays committed and pricing holds into the next quarter." If they start guiding to HBM oversupply or pricing rolls over while bit demand softens, that's the thesis breaking, not just a bad quarter. The cyclicality means I expect down quarters, so a price drop alone tells me nothing.
Foundry (I hold TSMC): the whole bull case is pricing power from a process lead, so my checkpoint is "leading-edge price increases stick and gross margin holds in the high-50s." If customers start pushing back on N3/N2 pricing or margins compress while leading-edge capacity is full, the moat (the lead that lets them charge more) is eroding even if revenue still grows. So I'm watching margin and pricing, not the top line.
The pattern: write the checkpoint against the specific bet, not the company in general. "Good business" can stay true while your reason for owning it quietly dies. And give it a number and a timeframe, otherwise you'll always find a way to argue the checkpoint hasn't failed yet.
Never said anything about Microsoft 😅
Also - what you are saying is accurate, but we typically call that Trading and not Investing.
Run the "fresh money" test: ignore your cost basis — if this were cash today, would you buy it at this price? No = you're just hoping to get back to even (the anchor you flagged), sell. Yes = not dead money, the red number's irrelevant. That one question already bakes in opportunity cost.
Just watch the trap: conviction in the new idea is usually inflated because it's currently going up.
Interesting conversation and intriguing- I wonder if there is some ideal mix of momentum and value investing that makes more sense.
But the answer is, as hard as it is to follow, that cost basis is irrelevant. As of today, do you have a better thesis than ADBE selling at 10% true fcf yield and 10% growth? I’d say it’d be hard to find another high quality company selling at such a low multiple. And their aggressive buybacks at such a low price are crazy. If the price stays this low you’ll end up owning the rights to a huge amount of cash flow.
You could make a case that ADBE is getting better - better guidance, lots of firefly cash ($300m?). Or you could say I don’t trust them because execs are fleeing and they’re being forced into a freemium model. For me they’re making good moves, growing well, adapting to AI and are really cheap for their stats.
What I’m skeptical on is it feels like the market is in this binary AI or SaaS mode. Anything good for AI buildout is bad for SaaS, so the money just moves over to semiconductors. While semiconductor cash is exploding, it’s still an extremely cyclical sector. At some point (and it may be a long time), that cycle will turn and the money will pour back to where there’s cash. At that point there will be a lot fewer adbe and pypl shares to go around.
"dead money" is optionality. As individuals, we are not forced to try and beat a benchmark. We do not have to be fully invested at all times. We set our own investment goals. We have our own timelines. We have our own risk tolerance.
When we have one really good idea, we can put a lot of money in it. When we don't have good ideas, we can buy an index or a money market fund.
Do not let other people's personal goals and priorities affect your own.
Camp 1 is for people that either have so many positions they can't juggle them on a daily basis (professional funds or people that doesn't want to trade etc.)
The returns on Camp 2 will vastly be better. Especially since in camp 2 you can easily switch to camp 1's stock if it runs.
Camp 2: Opportunity cost matters. Even if the thesis isn't broken, capital is limited. If I can identify businesses where I have materially higher conviction, it may make sense to redeploy rather than wait years for a recovery.
Bingo.
PYPL and ADBE value investors in from much higher prices are still waiting for the stock to triple to get back to break-even.
You can be right about "value" and wrong about timing. Or, you can be right about "value" and the market will never agree with you.
I use fundamentals to discover potential value investments, but wait for a stock to get into an uptrend before getting involved. While I'm waiting, my capital is working for me in rising stocks.
But uptrends are ephemeral and can turn quickly. I doubled down in sass during the may rally and instead of profit I just doubled my bags
Helpful :)
Well, yeah. If I was looking for S&P500 returns I'd definitely be full port VOO. I know I am supposed to be locked in and looking at the next 10 years, but doesn't opportunity cost come into play somewhere?
Consider tax harvesting as a factor. I have a position I am holding on for now to offset gains this year.
Thanks?
