Options Indicators

SMCI’s implied volatility is 74.03%, while its IV percentile stands at 21.91%, which suggests that although the absolute IV level is still high, it sits near the lower end of its own historical range. In other words, current option pricing appears relatively cheap, with volatility conditions on the low side rather than stretched. The IV/HV ratio of 1.08 also indicates implied volatility is only modestly above realized volatility, implying the options market is not demanding a large premium over recent actual price movement.

The Call/Put volume ratio is 2.37.

Large Trades

A CALL buy worth $112,800.00 was the largest displayed block, with 1,200 contracts purchased at the $40.00 strike expiring on 2026-09-18. With SMCI referenced at $40.35, this call was in the money, making it a fairly direct bullish position with intrinsic value already embedded. Strategically, this kind of trade points to upside participation with leverage and suggests the buyer was positioning for continued strength while using a strike close to spot for relatively high delta exposure.

A PUT buy worth $67,400.00 was the other displayed large trade, with 2,248 contracts bought at the $39.00 strike expiring on 2026-09-18. Since the stock reference price was $40.35, this put was out of the money, indicating a bearish stance that would benefit from downside follow-through rather than immediate intrinsic value. Overall, the large-order flow still leans bullish on balance: the biggest trade was an in-the-money call purchase, and aggregate premium flow favored upside positioning, which suggests institutional sentiment was moderately constructive even though some downside hedging or speculative bearish exposure was also present.

Strategy Reference

With IV percentile at just 21.91%, sellers may find limited premium collection attractiveness; instead, a call debit spread such as buying the $40.00 call and selling a $45.00 call for 2026-09-18 could reduce cost while targeting upside beyond the near-term range, while an investor seeking low assignment probability on the put side might consider selling the $30.00 strike put.
