Why it moves the price
Constrains units sold regardless of demand, and typically raises input costs, hitting both revenue and margin at once.
What separates a good call from a naive one
Distinguish demand problems from supply problems — a supply constraint with intact demand often means deferred rather than lost revenue, and the stock recovers as backlog converts. Check if competitors face the same constraint.
Measured impact
Every logged event is measured against real closing prices: the move from the close before the event, compared with the S&P 500 over the same window.
