Options Indicators

SMCI’s implied volatility stands at 70.63%, while its IV percentile is just 11.55%, which indicates that although the absolute IV level is high, it remains low relative to its own recent history and options are currently on the cheaper side rather than richly priced. With an IV/HV ratio of 1.05, implied volatility is only modestly above historical volatility, suggesting current option premiums are broadly in line with realized movement rather than carrying an excessive volatility premium.

The Call/Put volume ratio is 3.00.

Large Trades

A bullish call spread with a net debit of $50,400.00 was the standout large trade in SMCI, consisting of the purchase of 5,600 September 18, 2026 $40.00 calls and the sale of 5,600 September 18, 2026 $42.50 calls. With SMCI referenced at $35.64, both call strikes were out of the money, making this a defined-risk upside structure rather than an aggressive outright call purchase. The trader paid a net debit to establish the position, which signals a directional bullish bet on a move higher into expiration while also capping upside above $42.50 in exchange for lowering entry cost. Strategically, this is a classic premium-paid bullish spread that expresses upside conviction with controlled risk and a more measured return profile than a naked long call.

Overall, the large-trade flow points to a clearly bullish tone in SMCI. The fact that the only notable block activity was a bull call spread suggests traders were positioning for upside in a disciplined way, favoring a risk-defined directional bet rather than a high-premium speculative chase. That structure typically reflects constructive sentiment: participants appear to expect the stock to rise from current levels, but with a realistic target range rather than an open-ended breakout assumption.

Strategy Reference

For traders seeking premium collection with a low probability of assignment, selling a put spread below $31.00 or selling an out-of-the-money put with an expiration under 45 days may offer a favorable risk/reward profile given the subdued IV percentile and controlled downside assumption.
