    Treasuries, MBS, most non-corporate bonds all trade in eighths or 64ths. Coupon rates are in eighths as well. Commodities I think no longer do, but did until recently.

    Yes, that is what I meant. Thank you for expressing it more clearly!

    Passive investing isn't zero sum - it's positive sum. If you could buy a fraction of earnings from every business in the economy (i.e. both businesses that currently exist, and fut…

    Possibly -- you sell stock in fossil fuel companies, and reinvest in some other, hopefully more sustainable, company. It's not the divestment part that helps, it is the reinvestmen…

    Yes, the story is inaccurate: the study was about how power, not luck, changes perceptions. But the message is still right. It's easy to be a jerk if you are powerful. (And it's ea…

    This is factually incorrect, in addition to being bad advice. You take on debt when the net present utility of the purchase is greater than the price of the debt. Here's a simple e…

    I just checked their site, and they act less like a hungry startup, and more like a don't-care near-monopoly. Three examples: - You can't see prices for many items without logging …

    I misphrased above. The index fund will pay out a dividend if the underlying stocks do. Fortunately for investors, Companies are paying dividends less and less frequently, preferri…

    Articles like this are evidence that people are still surprised that capital grows faster than labour. At least in fair capitalist society the surest way to become wealthy (statist…

    You only pay capital gains taxes when you realize gains, not every year. Trump would pay 15% of $20B = ~$3B, so his net worth would be $17B. And this is assuming that his stock inv…

    The rational reason we don't build nuclear shelters anymore is because they're no longer effective. As weapon yields increased, it's become apparent that a concrete, underground hi…

    Is this a serious post, or are you being sarcastic? I honestly can't tell. JS the language of the future? Why? It has probably the worst gotchas of any language I've coded in, it's…

    The prize money is definitely a great idea. It'll probably be seen as a rich-company-PR move, but in hindsight, I think we'll see it as a sign of the times. Computer science seems …

    I think the clustering either has been trained very well, or uses a very conservative rule-based system. It seems to work great!
