GAMMA & VOLATILITY$MUMicron Technology, Inc.Open ticker analysis →
Options positioning in Micron Technology is stacking up around the $800 strike into Nov 6, 0.6% above where the stock trades at $795.23. Net gamma reads negative, a setup where hedging can speed moves up instead of slowing them down.
What happened
Across 536 contracts in the Nov 6 expiration, the heaviest gamma sits at $800. Net gamma exposure across the chain comes to roughly $124.59M negative, with about $302.2M 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, Micron Technology is a mega-cap semiconductors & related devices company valued near $967.5B, 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, $MU has been in a sharp slide, down 26.9% over the past 20 sessions, and it trades below its 20-day average of $914.90, near the bottom of that range between $782.00 and $1,108.55.

Three ways this could play out
Bullish continuation
If $MU pushes through $1,108.55, the top of its recent range, it breaks away from the $800 cluster. With negative gamma, hedging can add fuel and extend the move.
Bearish rejection
If $MU drops under $782.00, the bottom of its recent range, the $800 cluster stops acting as support. Negative gamma means hedging sells into the drop and can speed it up.
Neutral stabilization
If $MU hovers near $800 into Nov 6, the cluster does its job and expiration-week pinning becomes the story.
What to watch next
- $800: the peak gamma strike and the most likely pin into expiration.
- Nov 6: 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.
- $782.00 and $1,108.55: the edges of the recent trading range.
