SpotGamma Report for: 07/13/2021 AM

Daily Note:

Futures are flat overnight holding 4377. We see little change in gamma levels, with 4350-4400 the main range into Fridays OPEX. With that our model forecasts a very small max move today of 76bps/33pts. 4384 shows as a very large Combo Strike which may be a decent “fair value”/pivot reference for today.

As we grind toward the Friday OPEX we note that our intraday volatility metrics are once again pushing lows. This is seen in the middle chart wherein the “compression” reading is back to a historic lower bound. This is aligning perfectly with a “release” post-OPEX.  What is equally interesting here is that realized volatility (bottom chart) is well off of the lows seen at the start of July. 

The other unique chart comes from our EquityHub, which shows a very stable gamma to the downside. We’ve come to see that the “rate of change of gamma” has been useful in marking inflection points and as you can see below there is no real change in this SG Momentum (y axis) until markets break 4250. This picture is likely to change into Friday, but it suggests lower downside risks for today.
