 Insider Summary: Who Was Buying Shares on May 1 Friday trades by top managers are the best indicator of their confidence in the company. Here's what the May 1, 2026 filings showed: **Week's Key Signal — Jefferies (JEF)** Sumitomo Mitsui Financial Group opened a position of 6.43 million shares at $48.22 — that's $310 million. A purchase from scratch, director-level pool. When a Japanese financial giant enters a US investment bank with such an amount, it's not speculation. **Costar Group (CSGP) — CEO Votes with Money** Andrew Florance bought 71,430 shares at $35.20 for $2.5 million. Increased his stake by 4%. The price is near the bottom — a logical entry. **Sportradar (SRAD) — Collective Purchase** Four directors simultaneously bought shares on April 30: Walder (+66k), Yabuki (+10k), Kurtz (+8k), Ramanathan (+8k). Entry price ~$12.50-13.00. When the entire board synchronously builds a position, it's worth a closer look. **Sales:** • Sea Ltd (SE) — COO Ye Gang sold 20k shares at $85 • Air Products (APD) — CFO sold 2,714 shares at $303 • Andersons (ANDE) — director sold 19k at $78 My view: Sumitomo's purchase in JEF is an institutional-level signal. Sportradar with the board's collective entry is the second strongest signal. The rest is routine.
