The derivation that in total the passives outperform the actives is not a statistical result from historical data and doesn't require efficient market assumptions at all. It's just basic arithmetic that holds over any time period

It can crash even more violently by being removed from the index, which would happen if someone actually cornered the market for that stock as I described. My point is that the situation is unrealistic but in a completely different way than

In your hypothetical 99.9% passive scenario that doesn't work either because passive funds have long ago disallowed borrowing their stocks to short. If you start with a ~100% passive premise the reality is so different to what a normal

You didn't break down anything step by step. If you actually start with an 100% passive market and try having a single active investor in it nothing works. Funds can no longer buy and sell the basket of stocks they need. At that point

You can't sell stock short specifically to passive investors. You have to sell it into the market. And since you're trying to sell only that stock and passive investors are buying the whole market your actual net counterparty is a

How are you going to hoard "at no risk"? You're trying to corner the market for a given stock in an index pushing it's price way up and thus exposing yourself to the price crashing down and wiping you out. Meanwhile the

Your active strategies are not against passive traders, they're against other active traders. You can't create one of those differential bets trading only with index funds as they won't take the other side of the unbalanced p

One thing I didn't find on the website was a way to get an email with the actual data that was leaked so I can evaluate what's at stake. Showing it online would be poor privacy but sending it to the email should solve that. Some o

That's not a paradox. People will not defend your point of view, they will defend your right to express it even though they think you're wrong.

So time() is actually days since epoch with 1/86400 precision. That makes the Google solution to smear leap seconds with NTP instead of making them explicit make even more sense.

The X1 nano is the same width and height as a X220 but half the thickness and significantly lighter. The X13 is very close to that too on the lower end. What would you change in those? Having been a user of the old X lines throughout the ye

It's a little bit more than just culture. The Wayland protocol has made the compositor, window manager and window server concepts a single thing whereas in X those are provided by different applications talking a standardized protocol.

Sure, but as a side benefit. Maybe someone has actually proposed doing SMRs distributed over the country and heating all houses directly, but as far as I know it's never been done. It's usually preferred to have nuclear plants iso

Hydro and wind have the opposite seasonal variability to solar. And since some hydro allows shifting energy during the day even in summer it may be enough for a mix that solves both seasonal and daily/weekly variability. Build enough w

For 1) alpha is what you don't want when investing in index funds. Index funds can only stop working if they stop being able to track the market. That can happen if they're such a big part of the market that trading is effective

The difference is that our ability to tell if Brady was a good football player 10 years ago doesn't depend on his results today. Whereas a fund manager can turn out to have had a bad strategy all along whose gains are only wiped out af
