This is a repost from MacroTourist. Excellent site and co-host of The Market Huddle podcast. This post will be a little more technical, but it’s important, so I urge you to read on. Over the past couple of years there has been an increased interest in dealers’ gamma charts to help explain market movements. […]

Nomura Gamma Update 1/22/20
Heisenberg posted an updated gamma note from Nomura, and we like to note them here versus SpotGamma data. Nomura posts a combined SPX/SPY figure whereas we break the data out. The note and charts sync with much of what we have been saying: That long gamma is still in control. Last week, Charlie noted that […]
Trying to Call Tops
EDIT 1/28/20 : Here is an updated chart tracking this scenario. Jan 2018/Jan 2020 SPX Analogy by SpotGammaModel on TradingView.com Original Post: 1/24/20 With major moves higher over the last several months/weeks/days into January one can’t help but draw comparisons to January of 2018. We wrote an in depth review of Jan ’18 here and […]
Possible Gamma Flip Setup 1/7/2020
We’ve been tracking very high levels of call gamma the last several weeks that has recently stalled as we’ve hit heavy resistance around 3250 (blue arrow in chart below). During the last several days the zero gamma flip point has moved higher to ~3185 as you can see (green arrow): Iran has started launching missiles, […]
Nomura Gamma Report 1/7/20
Here is an updated Nomura gamma snapshot to compare vs ours. Note we both have gamma flip at ~3185 with peak gamma around 3275. He also sees 3250 as a “pin” much as we’ve shown in subscriber reports. Thanks to Heisenberg report. “And the same song remains—SPX Dealer ‘Gamma flip’ level is meaningfully below market”, […]
Stock Market Depth of Book: Liquidity vs Liquidity “Quality”
CME posted an interesting analysis called “Alternative Liquidity Measures” about volumes and depth of book. Their view is that liquidity doesn’t disappear during crisis times. The central argument is something along the lines of: “How can liquidity be worse if volumes skyrocket during market drops?” And that is actually a solid point. Yeah, you can […]
Expiration Is About Deltas
Much talk focuses on options market gamma and changes in gamma around expiration. But what may be the real catalyst around OPEX is a change in deltas, not gammas. When options expiration occurs (especially a large one like December) options are closed, expire or rolled. You therefore can have large positions change, which can cause […]
Nomuras Gamma Model 12/23/19
We like to post Nomuras model snapshot here to compare against ours. Our volatility neutral indicator is lower, but the top matches. Some of this may be explained by Nomura combining SPY and SPX.
Options Market Gamma Theory is All About Volume
Options market gamma numbers proliferate the market but its important to understand what exactly those numbers mean. Yes, positive gamma may indicate lower stock volatility. And when gamma flips from positive to negative that may indicate higher volatility. But the actual gamma number itself is an estimate of how much stock dealers will have to […]
BusinessInsider.com Talks Gamma
A good primer on market gamma from BI: So why do markets move at all if gamma is, like in this example, the big decelerator? Because it depends who owns it. Market makers use their gamma because they must. There is nothing worse than sitting on a position and bleeding white over time as your […]
