How News Affects CMF Options Pricing
Headlines and scheduled events drive implied volatility in two distinct ways. Pre-event, IV typically inflates as uncertainty about the outcome rises; this is the implied-volatility expansion that creates the long-vol setup. Post-event, IV typically contracts sharply as uncertainty resolves; this is IV crush, which makes premium-selling structures profitable when they survive the underlying move. The size of the crush depends on how stretched pre-event IV is relative to the realized move. Track CMF's implied vs realized volatility over the news cycle to size pre-event vs post-event positioning. For ticker-level dealer positioning context, the gamma exposure view shows whether dealers are positioned to amplify or dampen post-news moves.

- What CMF news moves options pricing?
- Three categories move single-name IV most aggressively: scheduled earnings releases (priced into pre-event IV, crushed post-event), unscheduled M&A or strategic announcements (rapid IV expansion, slower decay), and regulatory or legal events (drug-trial readouts, antitrust filings, FDA approvals). Routine news flow (analyst commentary, sector rotation) typically does not move IV meaningfully unless it triggers a cluster of rating changes.
