First Republic was last trading at $15.21, a day after being left out of a broader rally in bank stocks even as large U.S. lenders infused $30 billion in an unprecedented show of support aimed at allaying fears over the San Francisco-based bank's funding. JPMorgan Chase & Co is advising First Republic on its options to raise capital from investors, a source said on Monday. First Republic's market cap has shrunk to $2.2 billion from about $22.5 billion in 14 sessions of this month.
