SInce you asked how the PONZO model for SPY reacted to the recent swoon here's the update.
The forecast is actually a little gloomier for the next 6 months than the last look around so the past 2 days may just have been a warm up for some longer term selling. We'll take it one day at a time with the VIX down almost 9% today but still hovering in the 17-18 range.
