Options Indicators

Applied Optoelectronics currently has an implied volatility of 93.91%, while its IV percentile stands at 11.16%, indicating that although absolute volatility is high, it remains low relative to its own historical range and options are therefore cheaply priced rather than expensive. With an IV/HV ratio of 1.28, implied volatility is running above historical volatility, showing that the options market is still embedding a modest premium over realized movement expectations. The Call/Put volume ratio is 2.42.

Large Trades

A call purchase worth $48,500 stood out as the session’s notable large trade, with buyers taking 1,385 contracts of the 145.0 strike call expiring on 2026-10-09. With AAOI referenced at 121.57, this call was out-of-the-money at the time of trading, making it a clearly bullish directional bet on meaningful upside over the coming year. The relatively high strike versus spot suggests traders were targeting an extended rally rather than near-term intrinsic value, consistent with a speculative upside positioning or leveraged participation in a strong bullish outlook.

Overall, the large-trade flow in AAOI was decisively bullish. The session’s block activity was entirely concentrated in call buying, with no meaningful bearish large-trade counterpart appearing in the data, which points to a market tone favoring upside exposure rather than hedging or downside speculation. Taken together, the figures indicate that institutional-style activity was aligned with expectations for further appreciation in the stock, with sentiment best characterized as constructive and directionally bullish.

Strategy Reference

For a lower assignment probability, a call seller may consider the 175.0 strike expiring in the same 2026 cycle; alternatively, a bull call spread such as buying the 145.0 call and selling the 175.0 call can reduce net premium and margin exposure while retaining extended upside participation.
