JPMorgan Chase posted a third-quarter net loss of $380 million, or 17 cents a share, springing from $9.15 billion in extraordinary expenses, which came to $7.2 billion or $1.85 after tax. The company is expected soon to enter into a settlement of mortgage related investigations with the Justice Department, the Federal Housing Finance Agency, other federal regulators and states' attorneys general, with the total figure climbing as high as $13 billion, according to media reports. The Wall street Journal on Wednesday reported that a group of investors, including BlackRock ( BLK) and Neuberger Berman are seeking "at least $5.75 billion" from JPMorgan Chase, to recover losses on mortgage-backed securities sold to them by the bank. JPMorgan reported that its legal reserves as of Sept. 30 stood at $23 billion. That's an impressive figure, but if the media reports are accurate, investors could see a rough fourth-quarter bottom line. Still, JPMorgan's shares rose 2% from Oct. 10 -- the day before the third-quarter net loss was announced -- through Tuesday's close at $53.62. The shares trade for just 8.9 times the consensus 2014 EPS estimate of $6.01, among analysts polled by Thomson Reuters, which is one of the cheapest valuations among large-cap banks.
