Options Indicators

RKLB’s implied volatility is 104.69%, and with an IV percentile of 90.84%, current option volatility sits in a clearly elevated zone. That means options are priced expensively relative to their own recent history, and the IV/HV ratio of 1.11 suggests implied volatility is running modestly above realized volatility, reinforcing the view that premium levels are rich rather than cheap. The Call/Put volume ratio is 1.32.

Large Trades

A same-direction short PUT combination worth $21.25 million was the largest displayed trade, consisting of the sale of 5,094 July 17, 2026 $90.00 puts and 5,388 July 17, 2026 $85.00 puts. This is a net credit structure designed to collect premium, and with both strikes in the money versus the $67.35 reference stock price, it reflects a willingness to take on downside assignment risk while expressing a view that the stock will remain relatively stable or at least not experience a disorderly further breakdown beyond levels already implied. Strategically, it is best read as a premium-collection trade with a neutral-to-bearish tone, since the trader is monetizing elevated put premiums rather than aggressively positioning for a rebound.

A same-direction long PUT combination worth $15.49 million was the second major trade, made up of the purchase of 1,944 July 17, 2026 $115.00 puts and 2,132 July 17, 2026 $95.00 puts. This is a net debit structure that represents a clear directional downside bet, with both puts also in the money relative to the $67.35 stock price. The buyer paid substantial premium for deep intrinsic downside exposure, signaling conviction that bearish conditions could persist or intensify over time. Unlike the short-put structure above, this trade is not about premium harvesting or hedging income generation; it is a direct volatility-and-direction play aimed at benefiting from continued weakness in RKLB.

Overall sentiment is bearish. Across all large trades, bullish flow totaled $0.00 million while bearish flow reached $36.74 million, leaving a net difference of $36.74 million to the bearish side. The conclusion is straightforward: large traders were decisively positioned for downside or, at minimum, were unwilling to express upside conviction. That bias was driven by the combination of a sizable long-put directional purchase and a large premium-selling short-put structure that still carried a neutral-to-bearish posture rather than a constructive bullish one, reinforcing a clearly negative institutional tone around RKLB.

Strategy Reference

For sellers preferring low assignment probability, targeting a short put at a strike like $50.00, well out-of-the-money, could be considered; alternatively, for defined-risk positioning, a bear put spread using in-the-money puts could be implemented to limit margin requirements.
