GAMMA & VOLATILITY$NKENike, Inc.Open ticker analysis →
Options positioning in Nike is stacking up around the $33 strike into Oct 2, right on top of where the stock trades at $33.12. Net gamma reads negative, a setup where hedging can speed moves up instead of slowing them down.
What happened
Across 94 contracts in the Oct 2 expiration, the heaviest gamma sits at $33. Net gamma exposure across the chain comes to roughly $21.54M negative, with about $4.3M of premium traded.
This read uses the standard gamma-map convention, counting call open interest as positive gamma and put open interest as negative. Real dealer books can differ, so treat the sign as a guide to the setup rather than a certainty.
Why it matters
When net gamma is negative, hedging chases the move: market makers buy as the stock rises and sell as it falls. Breaks can travel further and faster than usual in that setup.
For scale, Nike is a large-cap rubber & plastics footwear company valued near $52.5B, so it takes serious money to move the stock, which is what makes signals like this one worth tracking.
With 1 days left, this is expiration-week territory, when pinning pressure around big strikes is usually at its strongest.
Zooming out, $NKE has been in a sharp slide, down 8.1% over the past 20 sessions, and it trades below its 20-day average of $36.49, near the bottom of that range between $35.02 and $41.93.
The numbers
| Stock price | $33.12 |
|---|---|
| Expiration | Oct 2 (1 days) |
| Peak gamma strike | $33 |
| Strike vs. stock | 0.4% below |
| Net gamma exposure | $21.54M (negative) |
| Premium traded | $4.3M |
| Contracts in chain | 94 |

| 20-day average price | $36.49 |
| 20-session change | -8.1% |
Three ways this could play out
Bullish continuation
If $NKE pushes through $41.93, the top of its recent range, it breaks away from the $33 cluster. With negative gamma, hedging can add fuel and extend the move.
Bearish rejection
If $NKE drops under $31.46, the $33 cluster stops acting as support. Negative gamma means hedging sells into the drop and can speed it up.
Neutral stabilization
If $NKE hovers near $33 into Oct 2, the cluster does its job and expiration-week pinning becomes the story.
What to watch next
- $33: the peak gamma strike and the most likely pin into expiration.
- Oct 2: expiration, when this positioning rolls off and the magnet effect ends.
- Whether net gamma flips sign as the stock moves. A flip from positive to negative often marks a volatility shift.
- $35.02 and $41.93: the edges of the recent trading range.
