IREN Ltd’s shares closed at USD 43.01, gaining 8.01%.
Large options activity in IREN featured a significant, bullish-leaning short put sale, counterbalanced by a bearish put combination. The flow indicates a constructive, premium-collecting bias in the face of high volatility, with the market showing a stronger appetite for defining a downside floor than betting aggressively on a sharp decline.
Options Indicators
IREN’s implied volatility stands at 128.68%, and with an IV percentile of 82.47%, current option volatility is in an elevated range, indicating that options are priced expensively relative to their own historical levels. The IV/HV ratio of 1.32 further suggests implied volatility is running above realized volatility, meaning the options market is embedding a notable premium for anticipated movement. In this setup, outright option buyers face richer premiums and steeper theta risk, while premium-selling structures or defined-risk spreads may offer a more efficient way to express a view. The Call/Put volume ratio is 1.04.
Large Trades
A put sale worth $2.61 million was the largest displayed trade, with 1,500 contracts sold on the January 21, 2028 $40.00 put. With the stock reference price at $43.005, this strike was out of the money at execution, making it a moderately bullish short-put position. Strategically, this trade points to premium collection with a constructive directional bias, as the seller is expressing confidence that IREN can remain above $40.00 through expiration or at least that downside risk will stay contained enough for the short put to decay favorably.
A $1.41 million same-direction double-buy put combination was the other key large trade, consisting of a purchase of 10,000 July 17, 2026 $34.00 puts for $0.92 million and a purchase of 10,000 July 10, 2026 $38.00 puts for $0.49 million. This was a net debit structure, and both legs were out of the money versus the $43.005 stock reference. The setup reflects a directional volatility bet rather than premium collection, using outright long puts across two expirations and strikes to position for a meaningful downside move in IREN, while also gaining exposure to a rise in volatility if selling pressure accelerates.
Overall, the large-trade flow leaned bullish, with total bullish premium at $2.72 million versus $1.54 million of bearish premium, leaving a net positive difference of $1.19 million. That points to a clear moderately bullish directional judgment. Even though there was a notable bearish put-buying combination aimed at capturing a sharp downside swing, the dominant flow was still led by the much larger out-of-the-money 2028 short put sale, which suggests investors were more willing to collect premium and lean constructively on the stock’s medium-term floor than to fully embrace a sustained bearish outlook.
Strategy Reference
Given the elevated volatility, sellers of out-of-the-money puts, such as at the $35.00 or $30.00 strikes, could target lower assignment probabilities, while defined-risk traders might consider a bear put spread, like buying a $40.00 put and selling a $35.00 put, to limit margin requirements while positioning for a moderate decline.
