Fresh off a $5.8 billion trading blunder, J.P. Morgan Chase (NYSE:JPM) is reportedly facing a lawsuit accusing the largest U.S. bank by assets of pushing underperforming in-house funds and investments on brokerage clients.

According to Reuters, the lawsuit was filed in New York State Supreme Court in Manhattan by a brokerage customer. The suit is seeking class-action status and compensatory and punitive damages.

In an effort to boost fees and profits, J.P. Morgan steered customers to invest in underperforming and unsuitable in-house funds, the lawsuit alleges, according to Reuters. The bank rewarded brokers who followed this strategy with bonuses, the suit says.

New York-based J.P. Morgan declined to comment on the report. 

Shares of J.P. Morgan dipped to session lows after the Reuters report and were recently off 3.04% to $34.98. While the company's shares have rallied about 5% so far this year, they have slumped 12.6% over the past 12 months.
