Mean Reversion - موجّه تحليل بالذكاء الاصطناعي
Use this Jeremy Grantham rule prompt to apply “Mean Reversion” to a specific company. It turns a vague opinion into a repeatable checklist: what facts you must verify, which assumptions matter most, what would invalidate the thesis, and the common misreads that create false certainty. Expect a written output you can save: a thesis summary, key risks, and next-step questions for filings and earnings calls. If a claim matters, require primary-source citations before you act.

Usage Tips
How reliable are analysis ratings for mean reversion strategies?
Mean reversion analysis is fairly reliable in judging the direction and magnitude of deviation but has inherent limitations in predicting reversion timing and path. Not all deviations from the mean will revert—sometimes structural changes create new equilibrium levels. For example, the sustained rise in technology company profit margins over the past two decades partly reflects structural advantages of platform economics rather than temporary deviation. Analytical ratings can help investors identify extreme deviation scenarios, but investors need to independently judge whether deviations are cyclical or structural. Combining mean reversion analysis with fundamental analysis is recommended, avoiding mechanical assumptions that all indicators will return to historical means.
Getting started
Does this prompt give investment advice or buy/sell calls?
No. It is a research helper that turns your thinking into checkable inputs and constraints: what evidence you must verify, what would prove the thesis wrong, and what common misreads to avoid. Treat the output as a draft, not a signal. Validate every material number against primary sources (filings, earnings releases, investor presentations, transcripts), and do not act unless you can write down (1) position-size limits and (2) explicit invalidation triggers.
What inputs should I provide for a reliable result?
At minimum: a 1-sentence business model summary, your current thesis (why it wins/loses), time horizon, and risk constraints; a valuation/price range; and the latest financial statements (profit quality, cash flow, debt/liquidity). Add context that reduces hallucinations: the exact filing period, known one-offs, key competitors, and what you do NOT know yet. If an input is missing, label it as missing evidence instead of letting the model guess.
Validation and boundaries
How do I validate the output?
Validate falsifiable claims one by one. Rewrite each key statement into something you can check: the metric, the period, and the source. Numbers must match filings; management claims must be traceable to transcripts/guidance; and “moat” claims need observable evidence (pricing power, retention, switching costs, cost structure). Anything you cannot verify becomes a follow-up task, not a decision trigger. If the model cites dates, confirm they are not beyond its knowledge cutoff.
When should I NOT act on the output?
If you cannot write down invalidation triggers, a position-size cap, or primary-source evidence for the key claims behind “Mean Reversion”, do not act. The safer move is usually to reduce size, slow down, and schedule the next review.

Identify Bubbles
Bubbles are identifiable before they burst. Watch for valuations 2+ standard deviations above historical norms.
→Patient Contrarianism
Being early is the same as being wrong. But in the long run, fundamentals always win.
→Asset Allocation Focus
Most returns come from asset allocation, not security selection. Get the big picture right first.
→Long-Term Forecasting
Seven-year forecasts based on valuations are remarkably accurate. Short-term is noise.
