2021 is starting out with what seems like decent IV overstatement potential, with current IV inflated compared to relatively dull market movements.
There is still opportunity to be had within various sectors, but opportunity is not distributed evenly…USO (oil) has an IV Rank approaching zero, whereas other sectors like silver (SLV), small caps (IWM) and biotech (XBI) have decent opportunity with ranks around 25 to 30.
