GAMMA & VOLATILITY$NVDANvidia CorpOpen ticker analysis →
Options positioning in Nvidia is stacking up around the $220 strike into Oct 14, 0.6% below where the stock trades at $221.30. Net gamma reads negative, a setup where hedging can speed moves up instead of slowing them down.
What happened
Across 106 contracts in the Oct 14 expiration, the heaviest gamma sits at $220. Net gamma exposure across the chain comes to roughly $136.53M negative, with about $59.68M 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, Nvidia is a mega-cap semiconductors & related devices company valued near $5.52T, so it takes serious money to move the stock, which is what makes signals like this one worth tracking.
With 0 days left, this is expiration-week territory, when pinning pressure around big strikes is usually at its strongest.
Zooming out, $NVDA has been in a steady climb, up 7.7% over the past 20 sessions, and it trades below its 20-day average of $228.32, in the middle of that range between $207.02 and $243.37.

Three ways this could play out
Bullish continuation
If $NVDA pushes through $243.37, the top of its recent range, it breaks away from the $220 cluster. With negative gamma, hedging can add fuel and extend the move.
Bearish rejection
If $NVDA drops under $207.02, the bottom of its recent range, the $220 cluster stops acting as support. Negative gamma means hedging sells into the drop and can speed it up.
Neutral stabilization
If $NVDA hovers near $220 into Oct 14, the cluster does its job and expiration-week pinning becomes the story.
What to watch next
- $220: the peak gamma strike and the most likely pin into expiration.
- Oct 14: 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.
- $207.02 and $243.37: the edges of the recent trading range.
