How CPRX iv/hv history Data Feeds Strategy Selection
Strategy selection on Catalyst Pharmaceuticals, Inc. options does not derive from any single metric in isolation. The iv/hv history view above sits inside a broader read: ATM IV currently sits at 5.2% and dealer gamma exposure is positive, so dealer hedging is mechanically mean-reverting. Combine the iv/hv history data here with the volatility-skew surface, dealer-gamma exposure, max-pain level, and upcoming-events calendar to build a positioning thesis. Risk-defined structures (credit spreads, debit spreads, iron condors) are usually safer than naked positions while the regime is uncertain; the data on this page anchors the inputs but does not by itself constitute a trade thesis.

- As of May 15, 2026, Catalyst Pharmaceuticals, Inc. (CPRX) ATM IV is 5.2% against 20-day realized volatility of 45.6%. IV rank is 0.9%. Realized volatility currently exceeds implied: an inversion of the typical equity volatility risk premium that often precedes IV expansion.
- What is the CPRX variance risk premium?
- The variance risk premium is the persistent gap between implied and subsequently realized volatility. In equity markets it averages positive because option sellers demand compensation for bearing variance shocks. CPRX is currently pricing inverted to the historical pattern, which is one input to whether short-vol or long-vol structures carry their typical edge.

High-rank regimes typically favor premium-selling structures (credit spreads, condors, covered calls); low-rank regimes typically favor premium-buying or long-volatility structures.
