Shares of First Republic Bank fell another 47% Monday as investors remain uneasy about the bank’s financial condition even after a group of the nation’s largest financial institutions teamed up on a $30 billion rescue package. Trading in First Republic shares was halted numerous times due to the volatility. The shares have dropped around 88% in the past two weeks. Over the weekend, First Republic’s credit rating was downgraded by S&P Global Ratings. Despite concerns about the banking sector, stock markets in the U.S. and Europe rose, with most bank shares showing gains.
