Applied Optoelectronics closed at $101.06, down 5.55%.
A standout bearish block shaped the session: a $208,700 out-of-the-money call sale at the 117.0 strike expiring in 2026, alongside a call/put volume ratio of 2.73. Despite elevated headline implied volatility, the low IV percentile signals cheap option pricing relative to Applied Optoelectronics' own history, making premium collection the dominant institutional theme.

Options Indicators
Applied Optoelectronics currently has an implied volatility of 90.65%, while its IV percentile is just 6.77%, which indicates that despite the headline IV level appearing high, current option pricing sits near the low end of its own historical range. In other words, volatility is on the low side relative to where this name has typically traded, and options appear cheaply priced rather than expensive. With an IV/HV ratio of 1.41, implied volatility is still running above realized volatility, showing that the market continues to build in a meaningful premium for forward uncertainty. The Call/Put volume ratio is 2.73.
Large Trades
A CALL sale worth $208,700 was the standout large trade in AAOI, with 1,128 contracts sold at the 117.0 strike expiring on 2026-10-02. With the stock reference price at 101.06, this call sat out of the money, meaning the seller was positioning above the current share price and expressing a bearish-to-neutral view that AAOI is unlikely to rally through that strike by expiration. Strategically, this kind of single-leg call sale is typically aimed at collecting premium while capping upside exposure at a higher level, reflecting expectations for muted upside or resistance well below 117.0.
Overall, the large-trade flow in AAOI leaned clearly bearish. The only notable block in the data was an out-of-the-money call sale, which points to premium-selling behavior rather than upside chasing, suggesting institutional participants were more inclined to fade rally potential than position for a breakout. Taken together, the bulk-order activity indicates cautious or negative sentiment, with traders signaling that meaningful upside in AAOI may be limited over this options horizon.
Strategy Reference
For sellers seeking low assignment probability, the 130.0 call with a later 2026 expiration offers an even farther out-of-the-money strike than the 117.0 block, though premium per contract will be thinner; alternatively, a bear call spread such as selling 117.0 and buying 130.0 can cap margin while still expressing limited upside in Applied Optoelectronics.
