It's boom time again for America's largest banks

Bank stocks overall have outperformed broader stock markets since the election

Shares in America’s banks are booming again, with Goldman Sachs Group Inc., J.P. Morgan Chase & Co. and Bank of America Corp. hitting fresh trading milestones Tuesday that seemed unreachable during the crucible of the financial crisis.

Investor expectations of higher interest rates, lower taxes, lighter regulation and faster economic growth under the Trump administration have added $280 billion in combined market value to the nation’s six largest banks since Nov. 8.

On Tuesday, shares of Goldman hit a record high, passing a bar first set in 2007 before the financial crisis. J.P. Morgan also hit an all-time closing high.
