How ZROZ iv/hv history Data Feeds Strategy Selection
Strategy selection on PIMCO 25+ Year Zero Coupon U.S. Treasury Index Exchange-Traded Fund 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 16.2% and dealer gamma exposure is negative, so dealer hedging amplifies directional moves.
