I just saw yesterday's numbers and something else occurred to me that I haven't seen discussed much recently: algorithmic trading. I'm wondering whether the volatility we've been seeing recently might have more to do with trading software than anything else. Certainly, high-speed trading thrives on (and feeds) big fluctuations. I'm guessing that AI is increasingly replacing good old-fashioned algorithms, which could make market behavior even more inscrutable. AI seems much more of a black box than explicit algorithms, so I'm wary of its effects. Does anyone know whether there is any specific regulation of AI driven trading? Do you think there should be?
