The options market for MicroStrategy (NASDAQ: MSTR) is showing significant bullish positioning with several large call option trades executed on May 16, 2025. Over $3M in premium flowed into the $420 strike price for calls expiring in just one week (May 23rd 2025). This suggests traders are anticipating a potential short-term upward move in MSTR shares.
Volume and Open Interest Data
The volume-to-open interest ratios for the MSTR call options are notably high, indicating substantial new positioning rather than closing of existing trades. The short-dated $420 strike calls show extraordinary activity. Total volume for the $420 calls reached 19,954 contracts versus open interest of just 1,791, creating a V/OI ratio of 11.141. Three separate BUY orders were executed on the $420-strike calls with combined premium value exceeding $3 million. The largest single trade involved 2,599 contracts of the $420 calls purchased at $5.65 each, representing a $1.5 million premium commitment.
A potentially bullish configuration has surfaced between the 415 and 435-strike calls. Executed within minutes of one another and carrying almost identical contract sizes, the two trades might appear to constitute the legs of a call spread that’s positioning for upside in MSTR over the coming week.
Short-Term Bullish Sentiment on MSTR
This heavy call volume indicates traders are positioning for a potential move above the $420 level before expiration on May 23, 2025, which is just 7 days from the trade date. The clustering of trades around the $420 strike suggests this is viewed as a critical resistance level.
Trade Side Distribution
The trade side distribution chart for MSTR $420 call options expiring May 23, 2025 reveals overwhelmingly bullish positioning with significant buyer aggression. The chart shows that 53% of the total $5.66 million in premium was executed at the ask price ($3 million). This indicates buyers were willing to pay sellers’ prices to secure positions. An additional 13% of trades ($750K) were executed above the asking price, demonstrating extremely aggressive buying interest. Bid-side executions accounted for only 21% ($1.2 million) of the total volume. While below-bid and mid-price executions represented just 8% ($474.5K) and 4% ($234K) respectively. With two-thirds of the premium paid at or above asking prices, this options flow suggests strong conviction among traders that MSTR could move higher before these weekly options expire in 7 days.

MicroStrategy’s stock price is highly correlated with the price of Bitcoin. This is largely due to the company’s strategy of holding a massive reserve of Bitcoin on its balance sheet. Since MicroStrategy began accumulating Bitcoin in 2020, the correlation between MSTR shares and Bitcoin has consistently ranged from 0.7 to 0.9. Consequently, the stock often moves in tandem with Bitcoin’s price swings. This strong relationship has led investors to view MicroStrategy as a proxy for Bitcoin exposure, amplifying both the stock’s volatility and its upside potential during crypto rallies.
Notably, Bitcoin’s price has been on a pronounced upward trend ever since Coinbase’s inclusion in the S&P 500 was announced. The event that sparked renewed institutional interest and optimism across the entire crypto sector. As Bitcoin continues to climb, MicroStrategy’s stock has mirrored these gains, further reinforcing the tight link between the two assets.
