Rocket Lab USA closed at $62.71, rising 6.54%.
Large options trades skewed heavily bullish, headlined by a $4.24 million short put at the $45.00 strike expiring January 21, 2028. The block flow was entirely one-sided toward put selling, with no offsetting bearish large trade to dilute that message. This indicates investors are comfortable underwriting downside at a much lower strike and are positioning for Rocket Lab USA to stay firm or trend higher rather than break materially lower.

Options Indicators
Rocket Lab USA currently has implied volatility of 82.65%, but its IV percentile is only 21.91%, which indicates that despite the high absolute IV level, volatility is still on the low side relative to its own recent history and options are cheaply priced rather than expensive. With an IV/HV ratio of 0.75, implied volatility is also running below historical volatility, suggesting the options market is pricing in less future movement than the stock has recently realized.
The Call/Put volume ratio is 2.05.
Large Trades
A $4.24 million short put was the standout large trade, involving the sale of 4,489 contracts of the January 21, 2028 $45.00 put. With RKLB referenced at $62.71, the strike sits out of the money, making this a bullish income-style position that expresses confidence the shares will remain above $45.00 through expiration. Strategically, selling an out-of-the-money long-dated put typically reflects either willingness to accumulate stock at a lower effective entry level or a view that downside risk is being overestimated, while collecting premium upfront.
Overall, the large-trade flow points clearly bullish. The block activity was entirely one-sided toward premium-selling on the put side, with no offsetting bearish large trade to dilute that message. Because the featured order was a sizeable out-of-the-money long-dated short put, the tone of the flow suggests investors are comfortable underwriting downside at a much lower strike and are positioning for RKLB to stay firm or trend higher rather than break materially lower.
Strategy Reference
For sellers seeking a lower assignment probability with a shorter commitment, the October 2025 $45.00 put offers a similar out-of-the-money cushion at a closer expiration, while traders who prefer not to post significant margin for a naked short put could instead use a $45.00/$35.00 bull put spread expiring in 2028 to define risk while collecting premium.
