How News Affects OST 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 OST'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.

Frequently asked OST news questions

What is the latest OST news headline?

The most recent OST headline (May 29, 2026) is "OS Therapies Announces the Publication of Four Articles on OST-HER2 and Osteosarcoma in Drug Discovery World". The five most recent stories with summaries and publication times are listed above, sourced from major financial news vendors.

How fresh is the OST news on this page?

News rows refresh roughly every 30 minutes during the trading day. The five most recent headlines are listed in publication-time order. Press releases from the company itself typically appear within minutes of the wire release; third-party reporting may lag by 30-60 minutes depending on the source.

What OST 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.

How can I track unusual OST options activity related to news?

Unusual options activity often precedes news by hours to days; the canonical signals are volume substantially above the trailing average concentrated in a small number of strikes, atypical put/call skew, and aggressive execution (at-the-ask sweeps or block prints). Cross-reference the per-ticker gamma-exposure and volume-history pages with the news flow above to triangulate informed vs uninformed flow.
