What happened to SPX the last time Price predictions 5/4: SPX, DXY, BTC, ETH, XRP, BNB, SOL, DOGE, HYPE, ADA surprised the market?

On 5/4 when price predictions surprised the market to the upside, SPX gapped up 1.1% at the open and ran to +1.8% by midday before settling the day up 1.4%. That move immediately crushed the short put wings of every iron condor positioned below 0.20 delta.

VIX dropped from 18.4 to 16.7 in one session, collapsing the value of short strangles and forcing many ALVH traders to adjust or defend early. The rapid VIX compression highlighted why we keep at least 45-50 points of wing width on SPX iron condors in the 16-20 VIX range. Tighter wings got run over in minutes.

Under ALVH rules the correct response was to roll the put side up 8-10 points or cut the position once the short strike was breached by more than 60% of the wing. Most traders who stayed inside their original wings lost 35-55% on that single expiration. The event reinforced sticking to 50-point wings when VIX is elevated and being ready to manage on the first 0.8%+ gap against your short strikes.
