Director RICKERTSEN CARL J buys 5.0K MSTR shares at $155.88; stock down 46.0% in 90 days.

RICKERTSEN, a director at Strategy Inc, acquired 5,000 shares at $155.88 on 2026-01-12, establishing an initial stake. The purchase occurs while MSTR has fallen 46.0% over the past 90 days and now trades at $162.23, which is 64.4% below its 52-week high of $455.90. His prior trades at MSTR show a mixed pattern: his 5 prior transactions at this ticker consist entirely of sells (on 2025-06-02 and 2024-08-13), with only 2 of 5 exhibiting well-timed outcomes at the 90-day mark. His cross-ticker track record across 2 prior buys shows an average 90-day return of -23.8%, though his 18 prior sells were well-timed 72.22% of the time. Notably, the company reported full-year net income was negative and annual revenue growth is -6.6%, creating a backdrop of operational headwinds.

Sell
26,390 shares
$9,827,744
Significance 7/10

Director Carl J Rickertsen sells 26,390 shares for $9.8M, reducing stake by 96.4%; prior sales at MSTR poorly timed (all 5 suffered 150%+ gains)

Director Carl J Rickertsen executed 2 separate sales totaling 26,390 shares for $9,827,744.39, a blended average price of $372.40, leaving him with only 980 shares post-transaction. This represents a 96.4% reduction in his MSTR holdings from 27,370 shares. The sale is material in size, and notably, his prior transaction history at MSTR shows a troubling pattern: all 5 prior sales executed on 2024-08-13 subsequently posted 90-day returns ranging from +155.2% to +158.6%, indicating those sales were poorly timed—the director sold before substantial gains materialized. While his cross-ticker track record shows a respectable 72.22% well-timed rate on prior sells (with -8.6% average 90-day return), his ticker-specific performance at MSTR is inverse: 0 of 5 prior sells were well-timed. This fundamental misalignment—poor historical timing at this specific security despite stronger cross-ticker results—merits investor attention in light of the company's current fundamentals: annual revenue decline of -6.6% and full-year net income of $-4.2B.

Buy
20,000 shares
$273,000
Significance 6/10

Director Rickertsen buys 20,000 MAGN shares at $13.65; stock down 41.1% from 52-week high amid unprofitable fundamentals.

Director Carl J Rickertsen purchased 20,000 shares (20.0K shares) of Magnera Corp on 2025-05-15 at $13.65, increasing his holdings from 21,306 shares (21.3K shares) to 41,306 shares (41.3K shares)—a 93.9% increase in position size. The purchase occurs at a price 41.1% below the 52-week high of $22.99, and the stock has declined 39.8% over the past 90 days and 10.6% over the past 30 days. Magnera faces material headwinds: the company is unprofitable with a net loss of $41,000,000.00 ($-41.0M) in the most recent quarter, annual revenue has contracted 7.1% year-over-year, and the market cap stands at $482,380,000.00 ($482.4M). A cluster pattern is present, with 2 other insiders also buying within the past 14 days. Rickertsen's own cross-ticker record shows his 18 prior sells achieved a 72.22% well-timed rate at 90 days, but his buy timing has been inconsistent; his prior purchase at MAGN on 2025-02-27 showed a 30-day return of -10.1%, and across his open-market buy history, none of his prior buys at the 90-day mark were well-timed.

Significance 6/10

Director Rickertsen buys 20,000 shares of MAGN at $20.33 for $406,532; position grows 1531.4% to 21.3K shares

Director Carl J Rickertsen purchased 20,000 shares at $20.33 on 2025-02-27, expanding his holding from 1,306 shares to 21,306 shares—a 1531.4% increase in stake. The purchase occurred 10.4% below the 52-week high and during a 30-day uptrend of +9.7%, suggesting entry near recent strength. However, the backdrop is material: Magnera Corp is unprofitable (full-year net income was negative), posted a latest-quarter net loss of $-60.0M on $702.0M revenue, and faces -7.1% annual revenue contraction. The director's prior cross-ticker track record shows 18 sells with a 90d well-timed rate of 72.22%, indicating historical skill in exiting before declines, though this metric does not extend to same-ticker prediction. The scale of this single discretionary purchase—targeting a meaningful director stake—warrants investor attention given the company's fundamental headwinds.

Sell
50,080 shares
$6,615,338
Significance 8/10

Director Rickertsen sells entire 50,080-share MSTR position for $6.6M; prior MSTR sales 100% well-timed, stock down 20.7% post-transaction.

Rickertsen completed a complete liquidation of his MSTR holdings through 5 separate sales totaling 50,080 shares for $6,615,337.57, reducing his position from 50,080 shares to zero. His transaction timing aligns with a sharp deterioration in company fundamentals: the latest quarter showed net income of $-102,559,000 against revenue of $111,442,000, paired with a negative annual revenue growth rate of -0.6%. Notably, Rickertsen's prior five trades at MSTR were all well-timed at the 90-day mark, with each sale followed by stock declines ranging from -74.4% to -75.3% over 30 days and -82.9% to -83.5% over 90 days. The stock has declined 20.7% over the 30 days following this filing and currently trades 31.3% below its 52-week high, providing early evidence consistent with his historical pattern at this ticker.
