Options trading for SpaceX is flashing bullish signals
SpaceX closed at USD 139.63, up 1.22%. Large options activity in SPCX showed a clash between a $10.38 million bearish synthetic put and a $5.81 million bullish bull put spread. The biggest trade leaned bearish through a short call and long put structure, while the second-largest trade collected premium on out-of-the-money puts, signaling long-term upside conviction. Despite the headline bearish size, additional call buying and premium-selling pushed the overall flow moderately bullish.

Large Trades
A bearish synthetic put position sized at $10.38 million stood out as the largest displayed trade, built through selling the December 18, 2026 $150.00 call for $6.52 million and buying the December 18, 2026 $115.00 put for $3.87 million, with the structure carrying a net credit of $2.65 million. With SPCX referenced at $139.63, the short call was out of the money and the long put was also out of the money, making this a clearly bearish directional expression that benefits if the stock weakens materially over time.
A bullish bull put spread with a net credit of $5.81 million was the other major displayed trade, using the June 16, 2028 $130.00 short put against the June 16, 2028 $70.00 long put, both struck below the current stock price and therefore out of the money. This is a classic premium-collection bullish spread: the seller is expressing confidence that SPCX can stay above $130.00 over the long run, while the purchased $70.00 put caps tail risk. The structure signals constructive medium- to long-term expectations and a willingness to monetize elevated downside premium without taking unlimited downside exposure.
Overall, the large-trade flow leans moderately bullish. Although the biggest individual directional bet was a sizable bearish synthetic put, the broader block activity showed stronger support from bullish premium-selling and call-buying interest, including a substantial long-dated bull put spread and additional upside call purchases.
Heavy put options activity in Micron is flashing a bearish sentiment
Micron Technology closed at USD 938.40, posting a 0.58 percent increase from the prior close. Despite the modest gain, options tape revealed a decisively defensive tone. A single purchase of $6.76 million in long-dated puts dominated the session, accompanied by a $250 thousand put buy. Both trades targeted out-of-the-money strikes, indicating institutions are loading downside protection rather than chasing upside momentum.

Large Trades
A PUT buy worth $6.76 million dominated the tape, with 1,200 contracts of the January 21, 2028 $500.00 put purchased. With MU referenced at $938.40, this strike sits well out of the money, making the trade a clear downside hedge or a longer-dated bearish position aimed at protecting against or positioning for a substantial decline over time. The size and long-dated tenor make it notable as a serious risk-off expression rather than short-term speculation.
A smaller but still meaningful PUT buy worth $250 thousand followed, consisting of 1,260 contracts of the September 18, 2026 $680.00 put. This strike is also out of the money versus the $938.40 spot reference, so it likewise reflects a bearish stance, likely focused on downside protection or a view that MU could weaken materially over the medium term. Although far smaller than the 2028 trade, it reinforces the same negative directional message from institutional flow.
Overall, the bulk-order flow is clearly bearish. Large traders concentrated exclusively in long puts, with no offsetting bullish large-trade activity, and both highlighted positions targeted out-of-the-money downside strikes across medium- and long-dated expirations. That pattern points to cautious sentiment and an expectation of meaningful downside risk rather than confidence in near-term upside.
