What happened to SPX the last time JOLTs Job Openings surprised the market?

The last notable JOLTs surprise to the downside (weaker than expected job openings) occurred on August 1 2023 when JOLTs printed 8.80M versus 9.35M expected. SPX reacted with a sharp 1.1% rally that day, closing up 45 points as the softer labor data raised rate-cut expectations and lowered recession fears in the near term.

Under the ALVH methodology, VIX was trading at 13.8 going into the print. The 0.8-point VIX drop that followed compressed the expected move and rewarded iron condor sellers who had sold the 15-20 delta wings with 45-50 point width. Those condors gained roughly 18-22% of the credit received within two days as volatility contraction overwhelmed the directional move.

Key takeaway for iron condor traders: downside JOLTs surprises typically produce positive SPX gamma with negative vega. When VIX sits below 15, favor wider wings (50-60 points on SPX) to reduce gamma risk while still collecting adequate theta. Tighten to 30-35 point wings only when VIX is above 18 and the market prices in larger post-JOLTs moves. Monitor the 4450-4550 zone for the next print as it represents current fair value.
