Evidence
0 logged events
Why it moves the price
The market prices in a probability-weighted set of value-unlocking actions, plus the chance the company is eventually sold at a premium.
What separates a good call from a naive one
Size and track record matter more than the headline. A small stake with no board leverage rarely changes anything. Watch whether management engages or entrenches — a long proxy fight can burn value.
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.
