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

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