Class-action lawsuit against Robinhood filed in Tampa

Background: Shares for GameStop closed at an all-time high — $445 per share — on Jan. 27, 2021. But the next morning, Robinhood shut down trading of the stock to its 10 million customers, citing market volatility.

• When those shares fell and then rose in trading the next day, Robinhood "chose to deny its customers access to the marketplace despite profiting off the customers who it lured in under the promise of market participation," said Shumaker's Michael S. Taaffe, who is representing the plaintiffs.

Flashback: Shumaker also sued Robinhood in March, when the trader was taken offline and investors left helpless during the biggest single-day point gain in the history of the Dow Jones Industrial Average.
