Futures have drifted higher to 4535 after a quiet overnight session. We look for another tight trading range (73bps) with resistance at 4550 & 4564, and support at 4514. The Vol Trigger jumped higher to 4495 which we mark as a healthy signal. This indicates that some put hedges are filling in below current prices which provides support.
We note a fair amount of QQQ gamma expiring today (20%) with quiet S&P expiration. However Friday shows ~20% of SPX gamma expiring, with the bulk of that position at 380. This could be a “pin pull” for QQQ/Nasdaq which sets up a move to its 385 Call Wall area. As you can see below the vanna model shows a left skew which indicates a more volatile (movement up or down) setup. This is not huge, but indicates a decent move is possible.

There are really no signals to indicate short term weakness in this market. Gamma is high which doens’t materially change until 9/17 OPEX, and we see little volatility across assets. Meme stocks are threatening to break out (ex: AMC, PLTR, GME) and traders seem intrigued by Chinese tech (ex: KWEB, BABA) which indicates a risk appetite.
Model Overview:
4550 top, 4500 support into 9/17 OPEX.
