The Hot Corner: Broadwood reloads STAA, Tether adds RUM, and Mullin sizes up Microsoft.

Monday, November 24, 2025 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.   📌Staar Surgical $STAA — Broadwood Partners bought $43 million in a new Form 4.   A massive purchase — easily the largest on today's list. Broadwood has been the anchor shareholder for years, and they're sizing up again as the stock works through a long bottoming process.   📌 Rumble $RUM — Tether Holdings bought ~$5.8 million per a fresh Form 4. The controversial stablecoin issuer keeps adding exposure. RUM sits more than 60% below its post-2024 election surge, and any outside capital stepping in here is notable as the stock tries to stabilize   Here's The Hot Corner, with data from November 21, 2025: Click the table to enlarge it. 📌 EchoStar $SATS — Darsana Capital raised its stake from 4.80% to 5.30%. A notable increase as the stock grinds sideways in a tight range following a huge run earlier this year. Position-building during consolidation is always worth watching.   📌 Ur-Energy $URG — The VP of Finance bought $183,000. Any insider support in this group stands out given the aggressive unwind of momentum. Shares of URG have halved since the stock peaked on October 15th.    📌 Sen. Markwayne Mullin — Bought a monstrous $250,001–$500,000 of Microsoft $MSFT.   If you want actionable trade ideas based off insider filings, join Hot Corner Insider risk-free.
