A new NBER working paper finds that members of Congress who become formal leadership (whips, chairs, etc.) dramatically outperform matched peers in personal stock returns — about a 47 percentage‑point annual advantage after ascension. The gains trace to trades timed around regulatory actions, party control, and home‑state/donor ties, suggesting leadership access translates into tradable information and corporate access.
— If replicated, this finding proves a concrete mechanism of office‑to‑private enrichment that should reshape debates on STOCK Act enforcement, blind‑trust rules, disclosure timing, and criminal/ethics investigations into lawmakers.

The article argues that internal challenges succeed or fail depending on how much political capital the incumbent appears to retain or lose (the ‘stock’ of a leader), citing Starmer’s interpersonal handling of Wes Streeting and historical examples (Attlee, Wilson) that show timing and perception drive whether challengers capitalize on vulnerabilities — directly linking to the idea that leader 'stock' after events determines successor prospects.
