Grab closed at USD 3.11, down 2.81%.

Despite the daily decline, options activity in Grab leaned heavily bullish, led by a large in-the-money long call purchase. A single trade in the October 2026 $3.00 strike dominated the session, alongside unusually elevated call volume relative to puts. The flow suggests traders are using long-dated upside exposure to position for a recovery, while implied volatility continues to command a premium over recent realized movement.

Options Indicators

Grab’s implied volatility is 65.76%, and its IV percentile stands at 66.53%, which places current volatility expectations in a broadly neutral zone rather than an outright elevated one. At the same time, the IV/HV ratio of 1.27 shows implied volatility is running above historical realized volatility, suggesting options are carrying a moderate premium versus what the stock has recently delivered, but not at a level that clearly signals extreme overpricing.

The Call/Put volume ratio is 12.53.

Large Trades

A call buy worth $118,800 targeted the October 30, 2026 $3.00 strike, with 3,300 contracts purchased while the stock reference price was $3.11, making the option in the money. This was a straightforward bullish single-leg trade, expressing upside conviction through long call exposure and suggesting the buyer is positioning for further gains in GRAB over a longer-dated horizon.

Overall, the large-trade flow was clearly bullish in GRAB. The activity was entirely concentrated in an in-the-money long call purchase, which typically reflects directional upside positioning rather than income generation, indicating that institutional-style flow was leaning toward continued appreciation in the stock.

Strategy Reference

For traders seeking a lower assignment probability while still selling elevated premium, the October 2026 $6.00 call could be considered as an out-of-the-money short strike against long stock or as part of a call spread. Alternatively, a bull call spread using the $3.00/$5.00 strikes offers defined risk with reduced upfront capital compared to buying the long call outright.
