GAMMA & VOLATILITY$MUMicron Technology, Inc.Open ticker analysis →
Options positioning in Micron Technology is stacking up around the $1,085 strike into Oct 7, right on top of where the stock trades at $1,088.00. Net gamma reads positive, a setup that tends to calm price swings and pull the stock toward heavy strikes.
What happened
Across 308 contracts in the Oct 7 expiration, the heaviest gamma sits at $1,085. Net gamma exposure across the chain comes to roughly $587.85M positive, with about $981.18M 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, Micron Technology is a mega-cap semiconductors & related devices company valued near $1.18T, 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, $MU has been in a steady climb, up 4.5% over the past 20 sessions, and it trades above its 20-day average of $1,029.64, near the top of that range between $887.61 and $1,108.72.

Three ways this could play out
Bullish continuation
If $MU pushes through $1,108.72, the top of its recent range, it breaks away from the $1,085 cluster. In a positive-gamma setup that takes real buying, so follow-through would say something about demand.
Bearish rejection
If $MU drops under $887.61, the bottom of its recent range, the $1,085 cluster stops acting as support. Dealers buying the dip usually slows that slide at first.
Neutral stabilization
If $MU hovers near $1,085 into Oct 7, the cluster does its job and expiration-week pinning becomes the story.
What to watch next
- $1,085: the peak gamma strike and the most likely pin into expiration.
- Oct 7: 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.
- $887.61 and $1,108.72: the edges of the recent trading range.
