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, right on top of where the stock trades at $149.94. Net gamma reads positive, a setup that tends to calm price swings and pull the stock toward heavy strikes.
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 $10.41M positive, with about $15.91M 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, 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 5 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 5.5% over the past 20 sessions, and it trades above its 20-day average of $148.40, near the top 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. In a positive-gamma setup that takes real buying, so follow-through would say something about demand.
Bearish rejection
If $SPCX drops under $104.83, the bottom of its recent range, the $150 cluster stops acting as support. Dealers buying the dip usually slows that slide at first.
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.
