One of the hallmarks of the US markets is that they are largely drive by institutions which tend to act rationally which, in turn, has resulted in a relatively stable market. Periods of volatility are driven by underlying factors that generally warrant the volatility. Contrast this with other markets around the world, such as China, where the markets are generally driven by individuals, and thus much more prone to irrational swings. Divorcing myself from the feel good nature of the hedgies getting their com-uppance, my guess is we are all better off with the former rather than the latter. However, I saw a tweet somewhere about regulators planning to step-in so the hedgies could level their ship - that bothered me as there is no chance they are going to step-in to help protect the individual investors on the way down.
