GAMMA & VOLATILITY$NVDANvidia CorpOpen ticker analysis →
Options positioning in Nvidia is stacking up around the $225 strike into Oct 14, 0.6% below where the stock trades at $226.32. Net gamma reads positive, a setup that tends to calm price swings and pull the stock toward heavy strikes.
What happened
Across 106 contracts in the Oct 14 expiration, the heaviest gamma sits at $225. Net gamma exposure across the chain comes to roughly $38.4M positive, with about $42.11M 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 positive, market makers hedge against the move: they sell into rallies and buy into dips. That tends to compress ranges, which is why heavily positioned strikes can act like magnets into expiration.
For scale, Nvidia is a mega-cap semiconductors & related devices company valued near $5.54T, so it takes serious money to move the stock, which is what makes signals like this one worth tracking.
With 2 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 7.3% over the past 20 sessions, and it trades below its 20-day average of $227.50, 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 $225 cluster. In a positive-gamma setup that takes real buying, so follow-through would say something about demand.
Bearish rejection
If $NVDA drops under $207.02, the bottom of its recent range, the $225 cluster stops acting as support. Dealers buying the dip usually slows that slide at first.
Neutral stabilization
If $NVDA hovers near $225 into Oct 14, the cluster does its job and expiration-week pinning becomes the story.
What to watch next
- $225: 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.
