What are the MRX aggregate Greek exposures?

As of Jun 30, 2026, Marex Group PLC (MRX) snapshot Greeks are net delta -$8.0M, net gamma $218.9K, net vega -$43.1K. These aggregate the dealer book across all listed strikes and expirations under the standard customer-versus-dealer sign convention.

What does the MRX net dealer delta tell us?

Net dealer delta of -$8.0M represents the directional exposure dealers carry from their option inventory. Dealers continuously hedge this exposure with stock, futures, or correlated instruments, so the size of net delta is also the size of hedge flow that will execute as spot moves.

How do MRX Greeks inform hedging?

Delta tracks first-order directional exposure; gamma tracks how quickly delta changes; vega tracks IV sensitivity. Aggregated dealer Greeks let traders read the dealer-positioning regime: long-gamma regimes mean-revert moves; short-gamma regimes amplify them. Vega exposure indicates how dealer P&L responds to vol shocks and hence the direction of vol-shock hedging flows.

How MRX options greeks Data Feeds Strategy Selection

Strategy selection on Marex Group PLC options does not derive from any single metric in isolation. The options greeks view above sits inside a broader read: ATM IV currently sits at 49.8% and dealer gamma exposure is positive, so dealer hedging is mechanically mean-reverting. Combine the options greeks data here with the volatility-skew surface, dealer-gamma exposure, max-pain level, and upcoming-events calendar to build a positioning thesis. Risk-defined structures (credit spreads, debit spreads, iron condors) are usually safer than naked positions while the regime is uncertain; the data on this page anchors the inputs but does not by itself constitute a trade thesis.

How to read the MRX Greeks profile

The chart above shows per-strike dealer-Greek exposures aggregated across calls and puts for the front expiration. Current net dealer gamma is $218.9K - a positive (mean-reverting) hedging regime. Net dealer delta of -$8.0M indicates short-delta dealer book - dealers are net short the underlying. Net vega of -$43.1K measures dealer P&L sensitivity to IV shifts - a 1-point IV move shifts book value by approximately $43.1K.

MRX Greeks regime and dealer hedging

Aggregate dealer Greeks compress 4 sensitivities (delta, gamma, theta, vega) into a single read on hedging behavior. In the current positive-gamma regime, dealer hedging is structurally mean-reverting: as MRX moves higher, dealers sell into rallies; as it moves lower, dealers buy into dips. This is the mechanical basis for the "pin to max pain" pattern. Gamma decays as expiration approaches; near-dated Greek exposures dominate the hedging flow.

Using MRX Greeks data for strategy selection

The Greeks profile is the input to most quantitative options strategies. Premium-selling structures (covered calls, iron condors, cash-secured puts) are negative-gamma, positive-theta, negative-vega - they pay you for being patient about realized volatility but get hit when realized exceeds implied. Premium-buying structures (long calls, long puts, long straddles, ratio backspreads) are positive-gamma, negative-theta, positive-vega - they pay you when realized exceeds implied but bleed time decay otherwise. With MRX IV rank at 26.9%, premium-buying has structural tailwind from cheap implied; pair with a directional thesis or event catalyst. Combine the regime read with the Greeks decomposition on this page to size structures correctly.
