How EDV iv/hv history Data Feeds Strategy Selection

Strategy selection on Vanguard Extended Duration Treasury ETF 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 13.1% and dealer gamma exposure is negative, so dealer hedging amplifies directional moves. 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 EDV variance risk premium?
The variance risk premium is the persistent gap between implied and subsequently realized volatility.
