    They might not have known it was SA specifically. That being said, they definitely knew a large fund with leverage was buying these stocks. The mechanism here (and I'm not an exper…

    Even in the optimistic case where SA did have alpha, the position sizing was way out of whack. Based on the volatility of the stocks they were buying, the Kelly Criterion meant you…

    Just to jump in: Citadel buying this portfolio says nothing about how Citadel feels about the stocks. It's the bread and butter of large HFT hedge funds; if you see someone that ha…

    Sure, a college student can tell you if a company is making or losing money. But there are ample examples of "good" companies crashing because they didn't react to shifts in the ma…

    From the financials, it's a little of both? Memory is the acute issue causing their struggles; their most recent quarter saw a gross margin of 4.5% (that's revenue minus the direct…

    The paradox is that the person most likely to do extra work is the person you want to hear from least. If someone felt the need to pay (for example) $5,000 to talk to me, it's prob…

    My understanding is that Musk doesn't have a controlling share of Tesla. So by the letter of the law, a SpaceX acquisition would qualify as a change in control (because we've gone …

    True, but "a better apple" is unequivocally less impactful than "you no longer have to walk to the river any time you want to drink a glass of water." I think it's easier to see if…

    Yeah, it gets weird when you start trying to compare human versus AI energy demands because you can turn a computer off, but you can't really turn a human off. Most studies indicat…
