The company disclosed the loss last week, saying it resulted from a failed hedging strategy.

The lawsuits filed on Wednesday in New York claim JPMorgan changed its risk model without telling investors. They say the shift led to the losses and claim company leaders misled investors.

One suit was filed by California shareholder James Baker. A second was filed by shareholder Arizona-based Saratoga Advantage Trust's financial services portfolio.

JPMorgan Chase declined to comment.

Its shares were up 6 cents by midday, trading at $36.30.
