Options Indicators

AST SpaceMobile’s implied volatility stands at 92.33%, while its IV percentile is 17.13%, indicating that although absolute volatility is high, it sits near the lower end of its own historical range. In other words, current option pricing appears relatively cheap and volatility is on the low side versus where AST SpaceMobile options have typically traded, with the IV/HV ratio of 1.45 showing implied volatility still carries a premium over realized volatility.

The Call/Put volume ratio is 1.77.

Large Trades

A put sale worth $9.48 million was the largest displayed trade, with 11,042 contracts sold at the $50.00 strike expiring on 2027-01-15. With ASTS referenced at $50.965, the strike sat slightly out of the money at the time, making this a moderately bullish income-style position that suggests the seller was willing to accumulate shares near $50.00 while collecting premium upfront. Strategically, this kind of large cash-secured-style put sale typically reflects confidence that the stock can hold around or above the strike over time, and it often signals constructive medium-to-longer-term sentiment rather than an outright short-term speculative bet.

A call spread-style directional buy was also prominent, structured as a same-direction double call purchase with a net debit of $1.39 million. The trade bought 4,000 contracts of the 2026-11-20 $60.00 call and 4,000 contracts of the 2026-11-20 $70.00 call, with both strikes out of the money versus the $50.965 reference stock price. As a bullish call combination entered for net debit, this position points to an aggressive upside view and a willingness to pay premium for a potentially large move higher into late 2026, rather than a premium-collection approach. The use of two out-of-the-money long call legs indicates a directional bet on substantial upside convexity and heightened participation if ASTS breaks materially above current levels.

Overall, the large-trade flow was clearly bullish. The dominant print was a very large out-of-the-money put sale that implied confidence in downside support near $50.00, while the featured call combination added a higher-volatility upside expression through long out-of-the-money exposure. Although there were some smaller bearish call sales in the broader tape, they were overwhelmed by the scale and character of the bullish flow. Taken together, the figures point to institutional positioning that favors upside or at least stability above key support, with sentiment best described as confidently constructive on ASTS.

Strategy Reference

For a low assignment probability, a seller could consider the 2027-01-15 $35.00 put, which sits roughly 31.00% below the $50.965 reference price and aligns with the bullish put-sale flow already observed; alternatively, a bull put spread at $45.00/$40.00 offers defined risk with substantially lower margin than a naked short put.
