Why it moves the price
A large block of previously unsellable shares becomes tradable, increasing float and supply on a date known well in advance.
What separates a good call from a naive one
The date is public, so it is partly priced in — the drift often begins a week or two early. The size of the unlock relative to existing float is what matters, and whether early backers are sitting on large gains they want to realise.
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.
