JPMorgan Chase (JPM -0.70%) is the largest commercial bank in the U.S., with about $4.5 trillion in assets. Chase Bank is the company's consumer and community banking subsidiary. Its other three segments are corporate and investment banking, commercial banking, and asset and wealth management.
JPMorgan Chase's roots go all the way back to 1799, when its earliest predecessor institution, The Manhattan Co., was founded. The Manhattan Co.'s founders included Alexander Hamilton and Aaron Burr. Later, tycoon J. Pierpont Morgan joined with Philadelphia banker Anthony Drexel to form a private merchant banking house called Drexel, Morgan & Co. in New York City in 1871.
The institution later became J.P. Morgan & Co. and went public in 1940. After merging with The Chase Manhattan Corp. in 2000, the company became JPMorgan & Chase.
Today, JPMorgan Chase remains a publicly traded company, which means it's owned by its shareholders. It trades on the New York Stock Exchange under the ticker "JPM." Since it's publicly traded, anyone with a brokerage account can invest in the stock and become a part-owner of JPMorgan Chase.
