ARM closed at 302.56 USD, slipping 0.11%.

A single large options structure dominated the session: a short call spread in November 2026 expiration worth $7.04 million in net premium collected. The trade involved selling the $310.00 and $320.00 calls, both out of the money. This block accounted for the bulk of notable activity and points to a neutral-to-bearish stance, with institutional flow positioning for capped upside rather than a breakout.

Options Indicators

ARM’s implied volatility is 72.27%, while its IV percentile stands at 58.17%, which places current volatility conditions in a neutral range rather than an extreme one. In other words, although the absolute IV level is relatively high, it is still broadly in line with ARM’s own recent volatility backdrop instead of signaling unusually expensive option pricing. The IV/HV ratio of 0.77 further suggests implied volatility is running below historical realized volatility, indicating options are not being priced at a pronounced premium versus the stock’s actual movement.

The Call/Put volume ratio is 2.46.

Large Trades

A call spread premium-selling structure worth $7.04 million in net credit was the standout large trade, built by selling the November 20, 2026 $310.00 call and selling the $320.00 call for the same expiration, both out of the money versus the $302.56 reference stock price. This is a same-direction dual short call combination, best read as a call-side spread strategy focused on premium collection rather than outright upside participation. With both strikes placed above spot, the trade expresses a neutral-to-bearish view that ARM is unlikely to make a substantial rally through those levels by expiration, and the seller is positioning for time decay and capped upside expectations rather than chasing directional upside.

Overall, the large-trade flow points to a bearish tilt in ARM options sentiment. The entire notable block activity was concentrated in an out-of-the-money short call premium-selling structure, which suggests institutional traders are leaning toward range-bound or weaker price action rather than preparing for a strong upside breakout. In short, the bulk-order positioning indicates restrained upside expectations and a market tone that is mildly bearish.

Strategy Reference

For sellers looking to mirror the bearish premium-collection view with lower assignment risk, the $320.00 call for November 2026 may offer a more conservative single-leg alternative; a defined-risk bear call spread such as selling the $310.00/$320.00 call spread remains suitable for those seeking to cap margin requirements while aligning with the observed institutional flow.
