- IV crush
Earnings and expected move API, GET /iv-crush/{ticker}
How much IV will NVDA lose after it reports, and what move does the current premium imply?
The pre-earnings IV build, the estimated crush and the move priced for the event. Returns the current and ATM IV, the estimated IV after the event and the crush in percent, the expected move and the historical average, and whether the nearest expiration is an earnings play.
The answer, in one call
Units first,
then the request.
IVs in percentage points; crush and moves in percent; straddle_price in dollars.
Crush estimate comes from past reports; expected move from the straddle covering the report.
