High conviction

This is a high-conviction signal — the insider is a first-time or occasional buyer, historically the strongest subset. Such buys have outperformed the S&P 500 by a median ~3% over the 30 days after the trade (n ≈ 3,001, 2024-2026). Past results don't predict the future. How we measure this ↗

Director David Mark O'Hara buys 110,865 shares ($507.8K) at $4.58, expanding stake 1589.2%; stock now -37.1% from 52-week high amid -$8.6M net loss.

Director David Mark O'Hara purchased 110,865 shares at $4.58 on 2026-05-26, increasing his holdings from 6,976 shares to 117,841 shares, a 1589.2% increase in his position size. The purchase occurs while CDZI trades substantially below its 52-week high of $6.96 (currently down 37.1%), and amid material operational headwinds: the company posted a net loss of $8,636,000 over its most recent full fiscal year despite generating quarterly revenue of $1,632,000. While annual revenue growth reached 69.8% year-over-year, the company's unprofitability and continued net losses signal significant execution or scaling challenges that investors should reconcile against the director's commitment of $507.8K to accumulate equity at current levels.

Heerema International acquires 2,070,000 CDZI shares at $3.34, raising stake to 22.78M shares (+10.0%)

Heerema International, a 10% owner of Cadiz Inc, purchased 2,070,000 shares at $3.34 on 2024-11-05 for $6,913,800, expanding its holdings to 22,783,965 shares. The transaction occurred as the stock recovered from a 52-week low of $2.15, with the current price at $3.75 representing a 30-day gain of +24.2% and a 90-day gain of +16.8%. However, the company remains unprofitable with a net loss of $8,872,000 in its most recent full fiscal year, against minimal quarterly revenue of $513,000. The insider's prior CDZI purchase on 2023-07-06 showed negative 90-day performance (-22.8%), and across all open-market trades, this insider has a 0% win rate at the 90-day mark with an average cross-ticker 90-day return of -22.8%, indicating a pattern of acquisitions that have not generated positive long-term returns.
