Alphabet closed at $344.98, down 1.26%.

Alphabet’s options market leaned decisively bullish on Thursday despite the modest pullback in shares, as large-block activity highlighted institutional confidence in downside support. A dominant $518,800 short put position anchored the flow, dwarfing a tiny $6,200 short call. The willingness to sell a deep out-of-the-money put at scale signals conviction that GOOGL will hold above $310 into late 2026, while the negligible bearish trade appears to be opportunistic premium harvesting rather than a genuine downside bet.

Options Indicators

GOOGL’s implied volatility is 31.31%, and with an IV percentile of 19.12%, current option pricing sits in the low end of its historical range, indicating volatility is relatively subdued and options are cheaply priced. The IV/HV ratio of 1.39 shows implied volatility is running above realized volatility, suggesting the market is still embedding a modest premium for future movement even though overall pricing remains on the inexpensive side versus its own history.

The Call/Put volume ratio is 1.79.

Large Trades

A $518,800 short put was the largest displayed block, with 2,180 contracts sold at the 310.0 strike expiring on 2026-10-23. With GOOGL referenced at 344.98, this put was out of the money at the time, making it a moderately bullish income-oriented position: the seller is effectively expressing confidence that shares will stay above 310 into expiration, allowing the premium to decay, while also signaling willingness to accumulate stock at a lower effective entry level if assigned. The trade’s size and out-of-the-money placement suggest a constructive stance rather than an urgent hedge.

A $6,200 short call was the other notable large trade, consisting of 1,244 contracts sold at the 400.0 strike expiring on 2026-09-18. With the stock below that strike, this call was also out of the money, pointing to a mildly bearish or capped-upside view, as the seller is betting GOOGL will remain below 400 through expiration and that the option will expire worthless. Even so, the small premium collected relative to the put sale makes this look more like opportunistic premium harvesting than a high-conviction bearish stance. Overall, the large-trade flow leans clearly bullish, because the dominant order was a sizable out-of-the-money put sale that reflects confidence in downside support, while the only bearish flow was comparatively tiny and does little to offset the broader constructive tone.

Strategy Reference

For traders seeking a low assignment probability on the short put side, selling the 280.00 strike in the same 2026 expiration could offer an even wider cushion below the market, though with a smaller premium; alternatively, a bull put spread such as selling the 310.00 put and buying the 280.00 put would reduce margin requirements and cap risk for a defined-income trade.
