Why "good earnings" stocks often dump the next day

VANNA works in opposite directions for the index versus single stocks.

Same mechanic. Mirrored positioning. Opposite outcomes.

Index level: clients buy puts off dealers. Dealers hedge by shorting futures. When vol gets crushed at FOMC or expiry, those short futures hedges get covered. Index rips. That's the VANNA/CHARM rally we see regularly.

Single stock level: clients buy calls into earnings. Dealers hedge by buying stock. When vol gets crushed post-earnings, those long stock hedges get sold. Stock dumps even on a beat. We saw that with multiple names last week.

Same vol-driven hedge unwind. One pushes the index up, one pushes the stock down.

If you can read which side the VANNA risk is building before the vol reset, you can see the move coming.

The setup is visible in the skew leading up to the event.

Index put skew steepening tells you puts are being loaded onto dealers. Single stock call skew piling up tells you calls are being loaded onto dealers into earnings. Both create the same dynamic hedging from dealers. The unwind direction is opposite.

Most retail reads the headline number after the print and reacts. The setup was visible 24 hours earlier in the surface.

How closely do you watch the skew?

Reading the skew before an event is the difference between seeing the trade and chasing the move. That's what we walk through inside the Ultimate Options Course.
