Skeptic-Investor Anti-Fan-Club Rule
If you can't articulate the major risks, you're in a fan club, not an investment.
Sasha's hardest psychological rule: before holding a stock you must be able to articulate the major risks and downsides of the business. If you can't — if you only say good things about the company, treat the CEO as infallible, and dismiss every concern — you're not investing, you're in a fan club.
The test is binary. Can you name what could materially impair this business? Bad business lines, weak strategic decisions, regulatory exposure, competitive threats, capital structure issues. If yes, you have a real position. If no, all you have is hope dressed up as conviction. The fan-club mode is a one-way ratchet: once you adopt it, every new piece of negative information bounces off, and you hold all the way to zero.
This rule sits upstream of valuation: even a perfect bottom-up model is useless if you've decided in advance that no risk can change your view. The skeptic posture is the precondition for the model to do its job.
- If you cannot name three serious risks to the business, you do not understand it.
- Loving a company and owning its stock are independent decisions.
- Sentiment-driven holding is religion, not investing.
- Every CEO has flaws; treating them as infallible is a leading indicator of disaster.
- The market doesn't care which side of the fan club you're on.
- Write down three serious downside risksBefore sizing a position, list at least three risks that could materially impair the thesis: regulatory, competitive, capital, executional, or macro. If you struggle to find three, you don't know the business yet.WarningIf your list is 'nothing — this company is amazing', stop and re-read the 10-K risk factors.
- Read competitor filingsForce yourself to spend time inside the rival's view of the world. Their moats and your company's vulnerabilities will surface together.
- Disconnect product affinity from share-price affinityLoving the product does not mean the stock is mispriced. Sasha loves AMD's chips and uses them in his work — and still sold the stock at target.
- Stress-test your thesis quarterlyAfter each filing, ask which of your downside risks is more or less likely than last quarter. If they're all 'less likely' you're probably anchoring; recalibrate.
- Sell when the risks materialize, not when you feel like itIf a downside risk crystallizes (e.g. competitive entry, regulatory action), evaluate whether your fair value still supports holding. Don't reflexively defend the position.
Retail investors bought AMC and GME on a fan-club thesis ('outsmart the hedge funds'), ignoring that the companies were issuing new share classes directly to them. The fundamental story was 'company prints shares, retail buys them'.
Sasha buys AMD's 'ridiculously priced processors' for his own work. When AMD hit his target price, he sold the entire position even though his product affinity was higher than ever.
Sasha built this rule in reaction to the 2020-2021 retail investing boom, where Robinhood and Trading 212 brought millions of new investors into stocks alongside YouTubers who treated investing 'like a team sport'. He saw the fan-club pattern crystallize around names like Tesla, AMC, and GME and developed the rule to inoculate his own decisions.
