MAIA director Guerrero Ramiro buys 20,000 shares ($30,000) at $1.50; holds 588.2K post-trade; stock up 28.0% in 30 days but unprofitable.

Director Guerrero Ramiro purchased 20,000 shares at $1.50 on 2025-05-08, increasing holdings to 588.2K shares. The acquisition occurred during a 30-day rally (+28.0%), when the stock trades at -62.4% from its 52-week high of $5.10, suggesting the purchase followed a sharp recovery from depressed levels. At MAIA specifically, his prior 5 trades show mixed outcomes: one generated exceptional 90-day returns (+218.0% in March 2024), but two produced 90-day losses (-15.6% and -25.9%), and his same-ticker timing pattern is weak (1 of 3 prior buys well-timed at 90 days). Most critically, MAIA itself is unprofitable with negative net income of -$4.5M on a $58.2M market cap, indicating material fundamental weakness. The purchase timing after a steep rally rather than at prior lows warrants investor scrutiny into whether the stock's recent recovery reflects durable operational improvement or near-term momentum detached from fundamentals.

Significance 4/10

Director Guerrero Ramiro buys 33,333 shares of MAIA at $1.50 amid -67.2% decline from 52-week high; unprofitable biotech.

Director Ramiro purchased 33,333 shares at $1.50 on 2025-03-03, expanding his holdings to 568,218 shares. The stock is trading at $1.67, down 67.2% from its 52-week high of $5.10 and down 11.6% over the prior 30 days. The company reported a net loss of $2.7M for its most recent full fiscal year. At this same ticker, Ramiro's prior 5 trades show mixed outcomes: his 2024-03-14 buy delivered a 218.0% 90-day return, but his 2024-11-01 and 2023-05-18 buys each lost 25.9% and 20.6% respectively over 90 days. His cross-ticker track record shows an average 90d return of +26.0% across 7 prior buys with a 40.00% win rate. The timing pattern at MAIA indicates only 1 of 3 prior buys were well-timed at the 90-day mark—a lower hit rate than his broader cross-ticker performance.

Significance 5/10

Director Guerrero Ramiro bought 73,333 shares of MAIA at $1.50 on 2025-02-24, expanding holdings 15.9%; stock now -65.9% from 52-week high.

Guerrero Ramiro purchased 73,333 shares at $1.50 on 2025-02-24, increasing his MAIA holdings from 461,552 to 534,885 shares, a 15.9% increase in position size. The purchase occurred near the lower end of the 52-week range ($1.30–$5.10), with the stock currently trading at $1.74, down 20.2% over 90 days and 65.9% below the 52-week high. His prior MAIA trades show mixed timing outcomes: 2 of 4 measurable buys achieved positive 90-day returns (the March 2024 and April 2023 purchases each posted substantial gains), while 2 resulted in losses. The company posted a full-year net loss of $2,735,987.00 against a $44,077,800.06 market cap, indicating ongoing unprofitability. This purchase represents a material accumulation at depressed valuations, though the insider's same-ticker track record shows inconsistent execution at identifying optimal entry points.

Significance 5/10

Director Guerrero Ramiro bought 53,418 shares of MAIA at $1.87 on 2024-12-13; stock down 60.8% from 52-week high, company unprofitable.

Guerrero Ramiro, a director, purchased 53,418 shares for $99,998.50 at $1.87 per share on 2024-12-13, increasing his holdings by 11.6% to 514,970 shares. The purchase occurred as MAIA trades at $2.00, down 60.8% from its 52-week high of $5.10 and down 16.3% over the past 30 days. Fundamentally, the company reported negative net income of $-2,735,987.00 for its most recent fiscal year, indicating ongoing unprofitability. Among Guerrero's 5 prior purchases at MAIA, 2 of 4 measurable instances posted positive 90-day returns, suggesting mixed timing skill specific to this ticker—notably, his March 2024 buy returned +88.5% at 30 days and +218.0% at 90 days, but his April 2023 purchase declined -40.8% at 30 days and -46.5% at 90 days. The current purchase at a depressed price level warrants monitoring given the company's unprofitable state and recent stock decline, though the director's prior mixed outcomes at this ticker provide limited forward-looking signal.

Significance 6/10

Director Guerrero Ramiro bought 88,534 shares of MAIA at $2.51; cluster buy pattern with 3 other insiders in 14 days

Guerrero Ramiro, a director, purchased 88,534 shares at $2.51 on 2024-11-01, increasing his holdings by 27.7% to 408.1K shares. This transaction is part of a cluster buy pattern, with 3 other insiders also purchasing MAIA shares within the past 14 days, which may signal coordinated confidence despite the company's recent unprofitability (net income: $-8.9M). However, the insider's timing track record at MAIA is mixed: of his 4 prior buys at this ticker, only 2 were well-timed at the 90-day mark, with outcomes ranging from +218.0% to -46.5%, suggesting inconsistent predictive value. The stock has recovered 13.8% over 30 days and 7.5% over 90 days since the prior buy in March 2024 (which returned +88.5%), but remains 43.5% below its 52-week high.
