Get post-dilution stock performance
GET
/api/v1/public/dilution/:ticker/performanceHow the stock traded after each historical dilution event (offerings, warrant exercises, conversions) at +1d, +7d, +30d and +90d, plus the aggregate mean and median across events. Returns 404 when there is no dilution performance data for the ticker. That is an absence of measurement, not a finding that dilution events had no effect. ⚠️ These are historical observations about past events. They are not a forecast and must not be presented as one.
