What happened: JPMorgan Chase is launching a digital investing service offering free or discounted trades, a portfolio-building tool, and no-fee access to the bank’s stock research. Anyone who downloads J.P. Morgan’s mobile banking app or uses its website can get at least 100 free trades in the first year. Forty-seven million people who already use the company’s banking app or website will have access to the new service, called You Invest. “There are customers out there who may not want to trust their credentials or their money to an app of the month,” said Jed Laskowitz in a CNBC story.
