Options Indicators
ARM’s implied volatility is 86.19%, and with an IV percentile of 77.29%, current option volatility sits in an elevated range, indicating that options are priced expensively relative to their own recent history. The IV/HV ratio of 0.89 suggests implied volatility is slightly below realized volatility, but overall the market is still assigning a rich premium to ARM options, so traders should remain aware of the higher cost of premium exposure at current levels. The Call/Put volume ratio is 1.28.
Large Trades
A bearish call spread with a net premium size of $0.38 million was the standout large trade in ARM options activity. This 2026-08-14 vertical involved selling 1,425 out-of-the-money 310.0 calls for $1.45 million and buying 1,425 out-of-the-money 320.0 calls for $1.07 million, producing a net credit of $0.38 million. With ARM referenced at $286.68, both strikes sit above the current stock price, so the structure expresses a moderately bearish to neutral view that the shares are unlikely to rally materially beyond $310.00 by expiration. Strategically, this is typically used for income generation while defining upside risk, allowing the trader to collect premium upfront while capping potential losses through the long 320.0 call.
Overall, large-trade sentiment in ARM was clearly bearish. The entire displayed large-trade flow was concentrated in a single bearish call spread rather than a mix of competing views, which suggests institutional positioning was focused on limiting upside expectations rather than chasing further gains. Because the trade used out-of-the-money short calls paired with higher-strike protection, the message is not one of outright panic, but of disciplined bearish positioning that expects ARM to remain below key upside levels over the option’s life.
Strategy Reference
For traders seeking to mirror this institutional posture with a lower margin requirement, selling the 310.0 call outright could offer a low assignment probability given the distance from the current price of $286.68, though a bearish call spread remains the preferable defined-risk approach for those unwilling to post uncapped margin.
