What Moves a Stock Price Is Not Growth but the Change in Narrative
Growth by itself generates no excess return; delivering on a narrative only earns you the discount rate. What sets the height of a stock price is the narrative; what sets its rise and fall is the change in the narrative.

Only a change in narrative produces alpha
The guest splits a stock price into two layers: what sets its height is the narrative, what sets its rise and fall is the change in the narrative, not the change in business momentum. Growth by itself generates no excess return; delivering on a narrative only earns you the discount rate. His example: a company's profit grows from 1 to 2, the discount rate is 10%, and reaching that in 10 years gives a fair dynamic PE of 15.3x; if it gets there in 5 years, the fair PE is 15.8x — growth explodes, but the formula's ought-to-be barely differs. 10 years to 5x gives a PE of 28.8, 5 years to 5x gives 30; 10 years to 10x gives 48.6, 5 years to 10x gives 49.9. The conclusion is that what determines PE is how high the ceiling is, not how soon you reach it.
— Zou PeixuanA-shares are an auction mechanism, not a hedging mechanism
US stocks allow shorting, bullish and bearish views cancel each other out, and the price is set by the market's average expectation — the midline of the normal distribution curve. A-shares basically cannot be shorted; the pessimists have no way to vote their shares out, so the price starts from the most optimistic expectation and works down one bid at a time, selling until the chips are cleared — that is, the shaded area to the right of the distribution curve equals the position where the tradable market cap can absorb the available capital. The price finally auctioned out can far exceed the average expectation. The root of this phenomenon lies in the trading structure itself, not in differences in liquidity.
— Zou PeixuanSet the ceiling first, then look at time to develop
The traditional approach treats growth as the cause and valuation as the effect; the guest treats the ceiling as the cause and growth as process verification. Every judgment in his reviews starts from ‘where is this company's ceiling’ rather than from how much next quarter's earnings will be. For A-share equity, a long-term discount rate of 10% is enough, which is roughly also the long-term compound return of active equity funds. Don't make too much of the discount rate. A-share active equity funds have beaten the S&P 500 over the long run, but with high volatility, which is consistent with an emerging-market risk premium. The US equity discount rate is about 8%, also long-term stable, and not much affected by changes in the risk-free rate.
— Zou PeixuanFalling rates do not equal rising valuations
Equity discount rate = risk-free rate + risk premium. The conclusion that a falling risk-free rate benefits equity assets is not supported by historical data, whether for A-shares, US stocks, Japan, or Europe and the US. If a falling risk-free rate necessarily benefited equity assets, stocks and bonds should always rise and fall together, but globally the more common pattern between stocks and bonds is a seesaw, so the risk premium is the more significant variable. A falling risk-free rate often means fewer growth opportunities — it is precisely because investors are unwilling to take risk and shift into fixed-income assets that the risk-free rate falls. At that point the risk premium typically rises by a more significant margin, the two offset each other, and the combined result is in fact stable.
— Zou PeixuanStock price equals the midline plus trading drift
Under the auction mechanism, stock price = midline position (fundamentals) + intercept position (trading drift). The midline position reflects the market's average expectation and is determined by fully objective fundamentals; the intercept position is the price drift brought by the trading mechanism, depending on the expectation distribution and liquidity. For two stocks with the same average expectation, the one whose expectation distribution is more dispersed and whose ceiling is harder to pin down drifts further to the right on the intercept and in fact gets a higher valuation, because you never know how absurd the most optimistic money can be. Liquidity itself can become a separate pricing factor; once the tide goes out, the intercept converges back at the same speed — the rise and the fall share the same source.
— Zou PeixuanHazy beauty plus liquidity equals the biggest gainers
The harder a stock's ceiling is to pin down, the more dispersed its expectation distribution, and the more its price is affected by liquidity. This explains why late in a bull market, once the market enters a positive-feedback loop of capital, the stocks with the best fundamentals may underperform the index. What matters most for price elasticity becomes ‘is there hazy beauty’. Hazy beauty plus short-term unfalsifiability plus flooding liquidity — put these three together and you have the portrait of the companies that rise most violently late in a bull market. Large-cap style versus small-cap style is more a result of valuation than a cause of it. The guest uses the microphone-to-speaker metaphor from Robert Shiller's Irrational Exuberance to explain this positive-feedback mechanism.
— Zou PeixuanIf you can reason logically, don't use induction
Core of the review: if you can reason logically, don't use inductive summary. Induction has a strict scope of applicability; reasoning does not. We live in a world of limited samples and limited time, where the law of large numbers may never get its turn, and specificity and randomness are the more important forces. All models are blind men touching an elephant; the parameters left out always far outnumber those included — it's just that when the external environment is relatively stable, the omitted parameters may temporarily not come into play. In a review, always make logical reasoning the main line and inductive summary the auxiliary.
— Zou PeixuanThe efficient market is dynamically efficient
The market keeps crossing above the fair value (the anchor), crossing below, crossing above again, crossing below again — crossing above is overvaluation, crossing below is undervaluation. Efficient market theory holds that the market returns to its proper value as fast as the market thinks possible. The market is dynamically efficient: neither absolutely efficient nor absolutely inefficient. If the market were absolutely efficient, research would be meaningless — just buy the index forever; if the market were absolutely inefficient, research would also be meaningless, because even if you judged something undervalued the market would never recognize it. It is precisely because it is oscillatingly, dynamically efficient that research has value. In the short run it is a voting machine, in the long run a weighing machine. The so-called long run is the moment when most people see clearly.

无风险利率下降往往意味着增长机会减少，恰恰是因为投资者不愿意冒险了、转而增配固定收益类资产，才导致的无风险利率下降。

Glossary
- DCF / Discounted Cash Flow
- A stock price equals all future cash flows within sight discounted back to today; the first principle of valuation.
- CAPM / Capital Asset Pricing Model
- The academic framework that derives the required risk premium from a stock's covariance with the market.
- Closed-form solution
- An exact answer expressible in a finite number of steps of formulas and elementary operations, obtained instantly once you plug in the parameters.
- Endogeneity
- Correlation between an explanatory variable and the error term, one of the hardest problems to handle in statistics.
- Business-momentum trap
- Earnings revised up quarter after quarter, beating expectations every year, PE percentile already at a historical bottom — it looks like a buy, but once the ceiling is pinned down the valuation gets compressed.
