GAMMA & VOLATILITY$SPCXSpace Exploration Technologies Corp.Open ticker analysis →
Options positioning in Space Exploration Technologies is stacking up around the $150 strike into Oct 2, 3.1% above where the stock trades at $145.47. Net gamma reads negative, a setup where hedging can speed moves up instead of slowing them down.
What happened
Across 160 contracts in the Oct 2 expiration, the heaviest gamma sits at $150. Net gamma exposure across the chain comes to roughly $25.23M negative, with about $52.78M 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, Space Exploration Technologies is a mega-cap computer programming company valued near $1.96T, so it takes serious money to move the stock, which is what makes signals like this one worth tracking.
With 4 days left, this is expiration-week territory, when pinning pressure around big strikes is usually at its strongest.
Zooming out, $SPCX has been in a steady climb, up 2.8% over the past 20 sessions, and it trades below its 20-day average of $148.59, in the middle of that range between $104.83 and $158.13.

Three ways this could play out
Bullish continuation
If $SPCX pushes through $158.13, the top of its recent range, it breaks away from the $150 cluster. With negative gamma, hedging can add fuel and extend the move.
Bearish rejection
If $SPCX drops under $104.83, the bottom of its recent range, the $150 cluster stops acting as support. Negative gamma means hedging sells into the drop and can speed it up.
Neutral stabilization
If $SPCX hovers near $150 into Oct 2, the cluster does its job and expiration-week pinning becomes the story.
What to watch next
- $150: the peak gamma strike and the most likely pin into expiration.
- Oct 2: 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.
- $104.83 and $158.13: the edges of the recent trading range.
