MicroStrategy Incorporated closed at $144.82, up 17.56%.
Large options trades reveal a split sentiment after the sharp rally. A bearish call spread with a $890.00 thousand net credit and a bullish call spread with a $911.16 thousand net debit both appeared, showing traders positioning for capped upside and controlled bullish exposure rather than aggressive unlimited gains.

Options Indicators
MSTR’s implied volatility stands at 85.12%, while its IV percentile is 50.79%, which places current volatility conditions in a neutral historical range rather than at an extreme. In other words, although the absolute IV level is high, relative to its own recent history MSTR’s options are neither especially cheap nor especially expensive. The IV/HV ratio of 0.98 also suggests implied volatility is broadly in line with realized volatility, indicating option premiums are fairly priced overall rather than showing a clear volatility premium or discount.
The Call/Put volume ratio is 1.81.
Large Trades
A bearish call spread with a $890.00 thousand net credit was the largest displayed combination, created by selling the 143.00 call and buying the 149.00 call for the 2026-09-11 expiration, 5,000 contracts each. With MSTR at 144.82, the short 143.00 call is in the money while the long 149.00 call is out of the money, making this a defined-risk bearish call spread positioned above the current stock price. The trader collected premium upfront and is effectively expressing the view that upside will remain capped, with the ideal outcome being that MSTR fails to sustain a move beyond the short strike area over time.
A bullish call spread with a $911.16 thousand net debit was the other highlighted trade, built by buying the 136.00 call and selling the 142.00 call for the 2026-09-04 expiration, 2,840 contracts each. Both strikes are in the money versus the 144.82 stock reference, so this is a vertical call spread that pays for upside exposure while reducing cost by capping gains above 142.00. Strategically, it reflects a controlled bullish directional bet rather than an open-ended chase, suggesting the buyer expected near-term strength but was willing to monetize that view within a defined upside range.
Overall, the bulk-order flow leans moderately bullish. While there was meaningful premium collection and several bearish or neutral-to-bearish call overwriting structures that point to expectations of capped upside, the broader large-trade picture still shows buyers more active in call ownership and bullish call spreads, indicating investors are positioning for additional upside in MSTR but often through defined-risk structures rather than aggressive unlimited-upside exposure. The takeaway is constructive sentiment with some caution: traders appear positive on direction, yet they are also respecting resistance and elevated option premiums by using spreads and selective premium-selling strategies.
Strategy Reference
For a low assignment probability selling strategy, a trader may consider shorting an OTM put below 130.00 or an OTM call above 160.00, but given MSTR’s high IV, a put credit spread or iron condor may better balance premium collection against tail risk without posting excessive margin.
