Should I adjust position size before GDP Growth Rate QoQ Prel?

Yes adjust your position size before the GDP Growth Rate QoQ Prel release.

Current VIX levels above 18 signal elevated macro risk and wider expected moves. Under the ALVH methodology this is the exact environment where you reduce size to protect the portfolio. Cut your iron condor notional by 30-40 percent ahead of the print.

Keep wing width at 25-30 points on the SPX to maintain a favorable credit-to-risk ratio. Wider wings in high VIX simply increase dollar risk without enough additional edge.

Enter or hold full size only after the number is released and VIX settles. Pre-event sizing discipline is the difference between surviving the move and giving back multiple days of theta. Reduce size now, reassess volatility and skew post-release, then scale back in.
