How FAST iv/hv history Data Feeds Strategy Selection
Strategy selection on Fastenal Company 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 26.5% 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.

- What is the FAST variance risk premium?
- The variance risk premium is the persistent gap between implied and subsequently realized volatility.
