What is the current MOMO gamma exposure (GEX)?

As of Oct 23, 2026, Hello Group Inc. (MOMO) GEX on methodology 2's assumed dealer book (dealers long the calls, short the puts, at 100% of open interest) is negative at -$6.0K of delta per 1% move. The put-minus-call delta balance (DEX) is -$584.7K underlying-equivalent. GEX sums the book's gamma across all listed strikes and expirations, in dollars of delta per 1% move.

Is MOMO in positive or negative dealer gamma right now?

MOMO's assumed dealer book is short gamma (negative GEX): its hedging sells into weakness and buys into strength to stay delta-neutral, which amplifies realized volatility and can accelerate directional moves where real dealers are positioned like the book. The book is an assumption, not observed positions.

What does MOMO GEX tell options traders?

GEX is a regime indicator: positive-gamma regimes favor mean-reverting strategies (premium-selling near established ranges); negative-gamma regimes favor momentum and breakout strategies. The same options-strategy structure can be appropriate or inappropriate depending on the gamma regime, so reading the sign and magnitude of GEX before sizing positions is standard practice.

Exposures are methodology 2's assumed dealer book as of Oct 23, 2026, all expirations. Assumes dealers are long the calls and short the puts, a share p of open interest each - here 100% of open interest (the GEX page sets the share). A date without a methodology-2 row is a gap; a value marked * is partial, averaged over fewer days, or may include contracts expiring that day or of an unreadable expiration: its reason is printed beside it. Its charm flow holds a cash level fixed: the spot.

As of Oct 23, 2026, Hello Group Inc. (MOMO) has negative GEX of -$6.0K of delta per 1% move on methodology 2's assumed dealer book (dealers long the calls, short the puts, at 100% of open interest). The put-minus-call delta balance (DEX) is -$584.7K underlying-equivalent. Negative GEX means the assumed book is short gamma: its hedging sells into weakness and buys into strength, amplifying realized volatility and accelerating directional moves where real dealers are positioned like the book.

MOMO Strategy Sizing in the Current GEX Regime

The assumed dealer book's GEX on Hello Group Inc. is negative (-$6.0K of delta per 1% move). In this regime, momentum and breakout strategies fit the regime: long calls or puts, ratio backspreads, calendar spreads positioned for vol expansion. Realized volatility tends to overshoot implied during negative-gamma stretches, hurting indiscriminate short-vol exposure. The gamma-flip level the GEX page draws - the spot price at which the book's GEX changes sign - is the most actionable anchor for sizing: through-flip moves trigger qualitatively different hedging behavior than within-regime moves, so risk-defined structures sized to the current spot may not stay sized correctly if a flip is near.

Reading the MOMO gamma exposure profile

The bars below split the assumed dealer book's GEX into each strike's call part and put part: where its hedging concentrates as spot moves through each strike. The assumed dealer book's GEX is negative at -$6.0K of delta per 1% move, so its hedging buys rallies and sells dips, amplifying realized volatility where real dealers are positioned like the book. The put-minus-call delta balance (DEX) is -$584.7K underlying-equivalent: the open interest leans call-heavy by delta, the same in every view - a lean, not a dealer position or a hedge size (the hedging a move sets off is GEX's). The book's vega exposure is $10.9K per vol point: the change in its option value for +1 vol point.

MOMO GEX regime and trading style

With the assumed book short gamma, Hello Group Inc. realized volatility tends to overshoot implied where real dealers are positioned like it, favoring long-vol structures: long puts/calls, ratio backspreads, calendar spreads positioned for vol expansion. Risk: indiscriminate short-vol exposure (covered calls, iron condors, cash-secured puts) gets hit when realized blows past the implied move. The current expected move of 9.30% is the anchor for sizing wings - structures with wings at ±1σ collect ~68% probability of staying inside the band.

How the assumed book's hedging on MOMO would feed the tape

Hedging is mechanical, not opinionated: a book's hedge follows its gamma. A short-gamma book buys rallies and sells dips, widening intraday ranges where real dealers are positioned like it: the mechanism behind "vol begets vol" episodes, where the first leg of a move triggers hedging that extends it. The gamma flip, which the GEX page draws, is the price where the book's GEX changes sign: moves through it can change the regime of realized volatility, not just the direction.

Practical caveats for trading MOMO GEX

GEX here is a model output, not a measured quantity: it assumes a dealer book long every call and short every put of open interest, at 100% of it, and cannot see who is actually short. Real books differ: call overwriting and protective-put buying fit the assumption, while heavy customer call buying or put selling contradict it, and then the real regime can differ from the sign shown. MOMO's current put/call volume ratio of 0.00 is a rough check on customer flow; lopsided ratios, well above 1.0 or below 0.6, are where the assumption deserves the most scrutiny. Cross-check with the IV-rank context on the volatility page: high-IV-rank regimes tend to coincide with negative gamma even when the headline number prints positive, because realized vol is already running hot enough to make hedging flows reactive rather than damping. When the implied move sits above 4% (9.30% here), the entire gamma profile compresses into the near-expiration tenors and the longer-dated GEX number becomes less actionable. Treat the gamma sign as a probability tilt, not a deterministic prediction.
