Regional Banks, Including Bank of America and Western Alliance, See Stock Rise Amid Optimism and Unusual Trades.

Bank of America and Wells Fargo shares are rising alongside other bank names after Western Alliance Bancorp reported quarter-to-date deposit growth exceeding $2 billion as of May 12, easing broader banking concerns. Berkshire Hathaway's moves in the banking space last quarter, including adding to positions in Bank of America and Citigroup and investing more than $950 million in Capital One Financial Corp, could also be helping boost bank stocks this week.
