Billionaire Ken Griffin's hedge fund Citadel LLC and the market maker Citadel Securities say they had nothing to do with the app Robinhood suspending some trading in stocks that have recently experienced a surge in volatility.

Tesla CEO Elon Musk said in a tweet Thursday that he "absolutely" supports Rep. Alexandria Ocasio-Cortez's call for the House Financial Services Committee to launch an investigation into Robinhood for its stock trade restrictions. 

The struggling video game retailer's stock has been making stupefying moves this month, wild enough to raise concerns from professional investors on Wall Street to the hallways of regulators and the White House in Washington.

Two Robinhood users filed separate lawsuits against the brokerage app Thursday after it and other apps restricted trading of certain securities.

Here's a closer look at what that means, how it works, and why it can cause massive spikes in stock prices like we've seen this week.
