Water, business, and biotech

Every day, we sift through the filings to spot where the real conviction lies – cutting through the noise to highlight the most meaningful insider moves.

 📌 Badger Meter $BMI — Chairman, President & CEO Kenneth Bockhorst purchased $258,573 via Form 4.

A CEO stepping in after a ~50% drawdown—that alone stands out. When the top operator puts personal capital to work after that kind of reset, it’s something we don’t see often.

Here’s The Hot Corner, with data from April 21, 2026:

📌 Barrett Business Services $BBSI — Royce & Associates increased its stake from 3.39% to 5.45% via 13G.

The small-cap value manager crosses the 5% threshold, building a meaningful position in a stock that was hit hard by AI-related fears, but recently held a key polarity level near 25.

📌 Sutro Biopharma $STRO — Perceptive Advisors filed an original 13G at 5.40%.

A healthcare-focused investor initiating a new position above 5% in the micro-cap biotech, as the stock attempts an aggressive reversal.
