Strike of the Deltas – Can Put Deltas Move the Market Down?

Bar charts of SPX INDEX option volume for calls and puts by strike from 2,150 to 4,100, highlighted at 3,118.

Interesting day in the market today as numerous China related headlines took away a futures rally that was testing all time highs. Its our view that much of the selling today was due to put buying. It seems there was a decent amount of slightly OTM puts trading, combined with a large move up in […]

Nomura’s McElligott Explains The ‘Perfect Virtuous Feedback Loop’ As Gamma Gravity Pins Equities “Intraday movement is squelched”.

From Heisenberg a great note from Nomura which syncs with what we wrote in recent weeks and to our subscribers. “Price movements over this summer once again clearly emphasized the spot/gamma/realized vol dynamics”, SocGen wrote, in a September note documenting a crucial dynamic that can always be described as “underappreciated” until everyone understands it. “All […]

Why Track Gamma, Not Delta?

This question of why we track gamma and not delta comes up fairly often. (For those needed a level one primer on delta vs gamma go here: OptionsPlaybook. If you need a primer on options market makers check here.) Our belief is that when options market makers (MM’s) start and end each day delta neutral. […]

SpotGamma vs Nomura

SPX volatility chart showing dealer futures vs price, high/low volatility zones, put floor at 3000 and call wall at 3150.

We like to post the banks gamma model output as way to check our own models. The two line up almost exactly. For now, US equities are “pinned” thanks to helpful greeks – at least until something really bad happens. “The fact remains that SPX will stay ‘sticky’ up here between the enormous 3100- ($9.4B […]

Action on “China Phase 1 2020” Selloff

SPY 2-min candlestick chart with Nov 20 options volume showing calls and puts clustered near 310.

Here is our view of the trading day today. The market started off the day long abut $2bn in gamma and at the lows of the day it was down to ~$1.75 bn. Despite the reduction that is still a hefty amount of gamma that supports a mean reverting market. On top of that we […]

Gamma vs Realized Volatility

SPX hourly candlestick chart shows gamma going under and over $1bn with historical volatility below.

Gamma appears to give traders an edge in predicting market volatility. Here we show the last few months of historical volatility as a quick method to back up this point. Volatility does not imply a direction in the market, just expanded movement. Often this is correlated with market drops, but also rapid rises as seen […]

The January 2018 Market Analogy

ESZ9 open interest bar chart showing yellow puts and blue calls by strike with volatility curves and red future line.

We’ve been seeing extreme call/put measures the past several weeks and these extreme measures only give way to more extreme measures. Nomura & JPM noted how heavy call positioning is relative to puts recently. There is also anecdotal evidence like this chart below, where Macrohedged notes: ” We cannot recall EVER seeing max OI for […]
