US Supreme Court justices signaled they are headed toward a narrow ruling on shareholder lawsuits as they weighed an effort to sue Nvidia Corp. for allegedly misleading investors over its dependence on crypto-mining revenue.

The justices heard arguments in Nvidia's appeal of a lower court's decision allowing a 2018 class action to proceed.

The case, which is in an early stage, accused the giant technology company of misleading investors about its exposure to the cryptocurrency industry.
