Many of the contributors to the subreddit forum r/wallstreetbets have been widely credited for working together to buy shares and drive up the stock price of GameStop, AMC Entertainment and others. The subreddit's description reads: "Like 4chan found a Bloomberg terminal," referring to a notorious social networking site and a computer software system used by finance professionals, respectively. Associate professor of finance and actuarial science Toby White explained the unusual mechanics that lead to the GameStop surge. "… The movements in stocks in GameStop are not really being driven by financial fundamentals, things like earnings, revenues, profits and dividends," White said. "They're more being moved by investor sentiment… the investors all getting together and having a unified message that we need to buy, and once we buy on, hold the line, don't sell." Drake junior and investor Mikayla Simpson said she didn't consider purchasing any shares because GameStop's stock was too volatile.
