Travel soccer took a toll and I was not able to post gamma updates Monday. 4700 is again the level with the highest concentration of gamma. More positive gamma = more anti-cyclical dealer hedging (buying into weakness, selling into strength), so prices should be sticky around this level and volatility low. Next target would be 4750. Interestingly call/put gamma ratio dropped to only 1.68, which is slightly bearish.
Enjoy!
