What happened last week? GameStop stock surged on Monday.
Robinhood temporarily paused trading of GameStop and other stocks.
The SEC on Friday said it was "closely monitoring" the situation.
What happened last week? An army of retail traders, led by Reddit's Wall Street Bets forum, poured money into shares of GameStop, a dying retail relic, as part of a battle against Wall Street short sellers.
GameStop stock surged to record highs
Some on Reddit said the stock rally was payback for the 2008 financial collapse. GameStop, which had nearly died in 2019, ended the trading week with a market cap of about $22.67 billion, according to Yahoo Finance.

Robinhood temporarily paused GameStop trading
As retail traders pushed GameStop, AMC, and other stocks to record highs, retail investing app Robinhood temporarily restricted trades. Representative Alexandria Ocasio-Cortez called Robinhood's decision to block trading "unacceptable." Robinhood users launched a class-action suit against the app.
The company said in a Friday blog post that its deposit requirements increased so rapidly that it had to block purchases to "comfortably" meet SEC regulations.
In the UK, meanwhile, the World Wide Robin Hood Society's Twitter following grew about 100-fold in a day, as users seemed to mistake it for the Robinhood app.
The SEC said it was "closely monitoring" the situation
After Senator Elizabeth Warren sent a letter to the Securities and Exchange Commission on Friday, the regulator said it would keep an eye on the situation.
In a statement, the agency said: "The Commission is closely monitoring and evaluating the extreme price volatility of certain stocks' trading prices over the past several days. Our core market infrastructure has proven resilient under the weight of this week's extraordinary trading volumes."
It added: "Nevertheless, extreme stock price volatility has the potential to expose investors to rapid and severe losses and undermine market confidence."
