The question you need to ask yourself is Why take what the OP wrote at face value? He hails from the crazy far Right.

Senator Elizabeth Warren of Massachusetts is asking the U.S. Securities and Exchange Commission to look into why GameStop stock has fluctuated in price so wildly in recent days, soaring from its usual $20 a share to over $440 at one point.
In a letter on Friday, Warren called on the SEC to prevent "these and future incidents of potential market manipulation." She asked the regulators to investigate whether securities laws were violated by hedge funds shorting GameStop stock or Redditors buying up shares to inflate its price.
"These wild fluctuations are just the latest indication that many private equity firms, hedge funds, and other investors, big and small, are treating the stock market like a casino," Warren wrote.
How does thr SEC stop stocks from having wild swings...that is the way the market works for the most part. Shorts and longs. You cannot have a free market and then try and regulate prices. It is one thing to remove fraud but not sure anything was illegal. HFs were short huge amounts of shares and got caught. It is risky to short shares and they got rammed hard proving how risky it is.
In my opinion the market worked pretty well punishing those who took on high risk activities.
Stock prices arw just fake valuations anyway with nothing to support it most of the time so this is what happens.
