get_dilution_performance

Get post-offering price performance: for each recorded offering, how the stock traded after it priced or closed. Use when assessing how the market has absorbed this issuer's past financings.

THIS IS HISTORY, NOT A FORECAST — it describes what happened after prior offerings and must never be phrased as an expectation, a price target or a prediction about a named company. An empty or unavailable series means no offering performance was measured, NOT that offerings had no effect and NOT that there were no offerings. ALWAYS RETURNS 200: read available and reason, never the HTTP status.

not_covered means this company has not been analysed yet, not that it has no dilution; an outage is a 5xx. NULL, absent or withheld means NOT MEASURED; it never means "no dilution", "no warrants", "no shelf" or zero. A numeric 0 is a MEASURED zero and defeats a null check: decide from the availability/withheld/reason field, never from the value itself.

Figures are as of meta.asOfDate, from filings read through meta.filingsThrough (a stale date predates anything filed since). Share counts are on one split basis; a row that cannot be rebased is omitted and counted, never published on a mixed basis. Included in Signal8 Pro: without it the call returns 403 FEATURE_NOT_AVAILABLE with requiredTier: "pro" (a tier upgrade; there is no add-on to buy).
