'Bond King' Bill Gross says he's dumping 80% of his regional bank holdings after making 'mucho bucks' in just three months

• PIMCO co-founder Bill Gross said he's selling 80% of regional bank holdings after making "mucho bucks." 
• The so-called "Bond King" snapped up shares in PacWest and Western Alliance just three months ago. 
• The fresh sale comes days after PacWest announced an all-stock merger with Banc of California. 

"Bond King" Bill Gross made "mucho bucks" on his regional bank holdings – and now he wants out. 

The PIMCO co-founder only just snapped up battered Western Alliance and PacWest shares three months ago, when a banking turmoil broke out following the collapse of Silicon Valley Bank.
