Shares of Western Alliance Bancorp edged up to their best day in 15 years on Tuesday amid a broad rally in the regional-bank sector and a disclosure that Citadel Advisors LLC took a major stake in the Arizona-based bank.
In a 13G filing with the Securities and Exchange Commission earlier Tuesday, hedge fund Citadel disclosed that it held 5.78 million shares of Western Alliance, or 5.3% of outstanding shares. That compares with the 1.31 million shares that Citadel previously said it owned at the end of 2022.
