The inability to hedge GEX causes LPs to lose profits by Loss-Versus-Rebalancing (LVR). Calculates estimate of market maker gamma exposure derived from S&P 500 index options Dependencies: pandas, numpy, holidays, datetime, requests, py_vollib, pyVolLib (my helper file in this directory), matplotlib "TRTH_GEX" requires a pandas dataframe of output from Thomson Reuters's Tick History, listing end of day SPX option quotes.

So, the moment that person sold that option a MM bought it; and for the MM to be "free" of directional risk it needs to take the delta of that option, multiply it by the multiplier of the underlying (in this case it's 100 shares of SPY per option contract) to know how many shares of SPY needs to SELL to be fully hedge (in this particular example, the number of shares to be sold by the MM is 29 and the amount of money the MM needs to use to delta hedge this position is 29 shares times 460 - the spot price of the SPY at the moment of this transaction). So, 9.81 Billion dollars the MM needs to buy or sell per 1% price move in the SP500 (taking as a reference the SPX).

Now that the trade is out there, the MM needs to constantly monitor this position to adjust its hedge, and this is when Gamma comes in and plays a fundamental role in the calculations.

Yes, the same -$19Bn that we calculated earlier in Excel!

After a handful of assumptions about the price process, the authors find that the instantaneous LVR, pronounced lever, assumes the form: To get the total LVR, just add up the instantaneous LVR over the path the price follows in time. The preceding logic tells us that is the rate of change in ! prove in Proposition 1 that LVR is equivalent to the profit earned by arbitrageurs, and the profit for arbitrageurs is profit that the LPs cannot capture! Put and call options are agreements between two parties on selling or buying assets for a specific price on a certain date. Still, under this assumption, puts carry negative gamma (not because theyre puts, but because the street is short them), and calls carry positive gamma. Finding out net gamma positioning isnt a trivial task as it involves figuring out the direction of options trades. The Primitive RnD team studies market design and MEV in the DeFi space. Yes, gamma tends to lose its powers in a high vol environment, as delta becomes less sensitive to underlying moves. And this largely depends on how "the street" is positioned. Gamma shows the potential amount of delta-hedging activity by the market makers. In the example, MMs are required to actively manage their position to mitigate their GEX. Also, let me assume the Implied Volatility at that strike is 20%, the Risk Free Rate is 2.8% and the dividend yield is 1.35% (continuously-compounded of course). Now that we've gotten that out of the way and have taken a leap of faith in relation to the assumption, let's rearrange the above GEX formula to be relate to a 1% move in price instead of a $1 move in price. We discuss how market designers, crypto traders, LPs and quants can build positions to reduce the GEX loss vector. When someone wants to buy or sell an option, a Market Maker (MM) will must likely be at the other side of that transaction; meaning that: If you want to buy an option, a MM will sell that option to you.
