Futures have consolidated some of those gains from yesterday – back to 4450. The SG gamma index is quite high at 2.2, which leads to a very tight estimated range of 0.56% today. We see resistance at 4477 and support at 4450.
The major range should hold as 4450-4500 into Fridays OPEX, as we see little to shift the major gamma positions before then. We now look for SPY traders to reload their options positions in the 445-450 range and “lock in” this area into Friday. Therefore we think the next several days will be a “snoozefest”.

Model Overview:
4500 top, 4400 support into 8/20 OPEX.
