Should I adjust position size before S&P 500, Nasdaq hit record highs on AI optimism, Middle East peace hopes - Reuters?

Before major S&P 500 and Nasdaq record attempts driven by AI optimism and geopolitical hopes, reduce your SPX iron condor position size by 30-50 percent. Elevated sentiment compresses implied volatility, shrinking credit received per wing width and lowering your edge under the ALVH methodology.

Current VIX levels near or below 15 signal caution. ALVH prioritizes setups where expected move fits comfortably inside your short strikes with at least 1.5 times the wing width as buffer. When markets grind higher on thin volatility, that buffer disappears quickly on any reversal, forcing early adjustments or losses.

Tighten wing width only after VIX rises above 18 and stays elevated for multiple days. Until then, smaller size preserves capital and keeps risk per trade under 1 percent of portfolio. Monitor spot VIX and VVIX spread. If VVIX is also low, implied vol of vol is cheap, meaning sudden vol spikes become more damaging to unadjusted condors.

Enter or add to full-size iron condors only after the news-driven rally exhausts and VIX climbs back toward 20 with expanding wing opportunities. Patience on size now avoids the common trap of oversized positions during low-vol euphoria.
