Strategy selection on Vanguard Mortgage-Backed Securities 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 17.8% and dealer gamma exposure is positive, so dealer hedging is mechanically mean-reverting.
