Options positioning in SOXL is stacking up around the $90 strike into Oct 23, 9.6% above where the stock trades at $82.11. Net gamma reads negative, a setup where hedging can speed moves up instead of slowing them down.
What happened
Across 250 contracts in the Oct 23 expiration, the heaviest gamma sits at $90. Net gamma exposure across the chain comes to roughly $13.58M negative, with about $218.75M 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.
With 1 days left, this is expiration-week territory, when pinning pressure around big strikes is usually at its strongest.
Zooming out, $SOXL has been in a sharp slide, down 29.4% over the past 20 sessions, and it trades below its 20-day average of $134.45, near the bottom of that range between $91.35 and $169.83.

Three ways this could play out
Bullish continuation
If $SOXL pushes through $169.83, the top of its recent range, it breaks away from the $90 cluster. With negative gamma, hedging can add fuel and extend the move.
Bearish rejection
If $SOXL drops under $78.00, the $90 cluster stops acting as support. Negative gamma means hedging sells into the drop and can speed it up.
Neutral stabilization
If $SOXL hovers near $90 into Oct 23, the cluster does its job and expiration-week pinning becomes the story.
What to watch next
- $90: the peak gamma strike and the most likely pin into expiration.
- Oct 23: 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.
- $91.35 and $169.83: the edges of the recent trading range.
