How does NBS Manufacturing PMI affect Iron Condor wing width?

NBS Manufacturing PMI directly influences SPX iron condor wing width through its impact on implied volatility and expected post-release movement. A hot PMI reading above expectations typically spikes VIX 1-2 points within minutes, forcing wider wings to maintain the same probability of profit. A weak reading usually compresses VIX, allowing you to tighten wings and collect more credit.

Under the ALVH methodology, treat NBS PMI as a scheduled volatility event. Before the release, keep wings at 45-50 delta on both sides when VIX is below 18. After the number prints, immediately adjust wing width based on the new VIX level: add 5-7 points of width for every 1-point VIX increase above 18, and reduce width proportionally when VIX drops.

Practical rule: if PMI surprises by more than 0.5 points, expand short strikes by at least one full strike interval and widen the wings to keep the short strikes at 16-18 delta post-event. This prevents the iron condor from being pinned near the short strike during the volatility expansion. Monitor the 10-minute VIX reaction chart after the release and resize wings within the first 30 minutes of trading to align with the new realized volatility regime.
