The Story Changes, the Price Follows
The mechanism by which equity prices respond to narrative shifts: when the underlying story about a business changes, the discounted-cash-flow translation changes with it, and prices reset on a timescale faster than fundamentals can move.

When the story changes — when new evidence, new technology, or new competitive dynamics revise expectations about future cash flows — the price changes accordingly. Critically, this happens fast: a narrative change that reduces expected growth from 15% to 5%, compresses expected margins from 25% to 15%, or raises the discount rate from 10% to 14% can reduce the present value of future cash flows by 30-50%, even though current quarter financials look unchanged.
