Informe GT Gamma Levels

Feb 11, 2021 | 0 Comentarios

Futures are up slightly to 3914. We are somewhat surprised to see the SPX Call Wall jump to 4000 today, with the SPY Call Wall holding 395. This shift is the result of 15k net puts added to the 3900 strike, which increases 3900 as a floor, and confirms a higher SPX price range. For today we anticipate a tight trading range of ~60bps, with 3 major levels: 3896, 3923, and 3947.
Yesterdays intraday volatility did add a bid more weight to tomorrows OPEX, which could signal a bit more volatility next week. In particular it reduces gamma at strikes up into the 3950 range which could reduce resistance overhead.
It was only a few weeks ago that we wrote about some of the risks that we saw in markets. Primary to this was:

1) Low hedging

2) Low levels of shorting

3) High levels of levered speculation (calls + margin).

The GME saga cleared out much of this risk, for about 10 days. We can see many signs of rampant speculation in areas like “pot stocks” (ex: TLRY +50% y’day), and “short funds” are struggling. Lastly we came across this chart from the CBOE, which shows a 3 month trailing put/call ratio (total stocks, not just SPX).

CBOE 3 Month Put Call Ratio

We understand there are “stimulus based” bull cases for higher asset prices, and we are not here to comment on longer term, macro themes. Our models are generally tied to the “OPEX cycle” and are not intended to look out much past 4-6 weeks. Based on these notes above and this cycle we believe we can highlight periods of higher risk and volatility, which appear to be aligning post 2/19 expiration.

Macro Note:
