A look at how members of Congress trade stocks, framed as a sign that lawmakers may profit from their own policy decisions.

• Nancy Pelosi bought over $3 million of Nvidia shares in 2022, just hours after backing the Chips bill.
• That bill sends $52 billion in grants and tax breaks to U.S. chip companies like Nvidia, plus up to $200 billion more for tech research.
• To fund the buy, she sold about $2 million of Visa stock.
• Critics call the timing insider trading, since the law directly boosts the company she bought into.

Outlook: Watching what Congress buys will keep being pitched as a stock-picking strategy, and the debate over banning lawmaker trades is likely to grow.
