Options Indicators

RKLB’s implied volatility is 99.28%, and with an IV percentile of 71.71%, current option volatility sits in the elevated zone, indicating that contracts are priced expensively relative to their own recent history. The IV/HV ratio of 1.05 suggests implied volatility is only modestly above realized volatility, so while premiums are rich on a percentile basis, they are not drastically detached from the stock’s actual movement profile. In this setup, option buyers are paying up for volatility, while premium-selling or defined-risk spread structures may offer a more efficient way to express a view. The Call/Put volume ratio is 2.44.

Large Trades

A CALL purchase worth $2.88 million was the standout large trade, consisting of 1,800 contracts of the January 21, 2028 $175.00 call bought for $16.00. With RKLB referenced at $76.20, this strike is deeply out-of-the-money, making it a high-conviction bullish position that is targeting substantial upside over a long-dated horizon. The use of a far-out strike and long time to expiration suggests the buyer is seeking leveraged exposure to a major upside move rather than near-term hedging, reflecting a directional bet on significant appreciation in the stock over time.

Overall sentiment is clearly bullish, with total bullish large-trade flow at $2.88 million against $0.00 million bearish, leaving a net bullish difference of $2.88 million. The directional read is firmly positive, as the only notable large trade was a sizable long-dated call purchase, and its deeply out-of-the-money structure points to an investor willing to pay premium for upside optionality rather than defend an existing position. This pattern indicates speculative optimism and a willingness to position for a potentially outsized longer-term rally in RKLB.

Strategy Reference

Given the elevated IV percentile, a premium seller could consider writing the January 2028 $25 put for a low probability of assignment, while a trader preferring defined-risk exposure might structure a bullish call spread, such as buying the January 2028 $80 call and selling the $120 call, to reduce capital outlay.
