SPX Gamma Levels Firday

Uneventful day, gamma levels basically stay the same. 4700 remains a major resistance, 4650 acts like a magnet. At 4630 we have a put barrier (gamma notiona -19.5M) which should add support. I highly recommend the latest Goldman piece about the historic option volumes in November (see Zerohedge). Its all about options/gamma flows. Cheers!
