Seems to me that many people do not care about part 3 anymore.

The headline is brilliant.

Indeed. It's so much bigger (in notional terms) than the underlying stock market that you can manipulate it by making large bets in the derivatives market, then move the underlying cash markets with much smaller bets, and collect profi

Not binary. Each weighing can give you left, equal, right. So a ternary tree, if you want.

by FabHK 2mo ago
Exactly. Same kind of thinking gives you bounds on what can be done. For example, can you do 13 marbles in 3 weighings? 2 13 < 3^3, so maybe (though I think not). Can you do 14 marbles? 2 14 > 3^3, so definitely no.

Boat + bowling ball => level drops. 1) Imagine pushing the boat down into the lake, displacing water. The level would go up . 2) Imagine the ball instead of being in the boat, is attached under the boat by a rope. Same thing. (Imagine

That's because you get (particularly initially) quite some reduction of risk with little loss of expected return. Diversification (incl. across asset classes) is the only free lunch in finance. If you want to argue that bonds and stock

BTW, you are correct technically that if the expected return of the investment is positive, then you maximise the expected return by putting in everything now all at once. However, maybe you want to reduce the variance. Or you want to trade

While banks often pay crap rates, real rates (e.g. from government bonds) have largely been positive (except the short end after GFC and COVID). https://fred.stlouisfed.org/series/REAINTRATREARAT10Y https://

Wonder what would happen if the objective instead were to minimise sum of quadratic wait times (ie, penalise long waits explicitly).

Reminiscent of the resource curse, the observation that many countries "blessed" with an abundance of natural resources actually fare pretty badly (including lots of corruption). https://en.wikipedia.org/wiki/

We agree. New buildings can be designed and built with induction stoves without destroying precious Japanese cooking culture, just as gas (and wood for that matter) has been replaced elsewhere. And medium term Japan does not lack the resour

Apropos, anyone else saw "fast user switching" in Tahoe turn into "excruciatingly slow user switching which after a minute of switching without success rebooted the whole damn machine"?

Induction is the trick. It's nearly as fast as gas.

Ah, interesting, so em-dash without spaces really is more of a US convention. My LLM pushed back against that assumption of mine :-)

Furthermore, the conventions for the first (parenthetical) use case, as far as I understand, are either em-dash without spaces (Anglosphere convention), or en-dash with adjoining spaces (Continental convention: German, French, etc.), but ra

If you're talking about dodgy accounting at hyperscalers, a larger worry might be that they are overstating profits by depreciating their assets (such as datacenters and CPUs/GPUs) too slowly. Estimates are that this could oversta

FWIW, a firm can go bankrupt and the stocks be worth zero with the bond holders being paid 100%. In fact, that's sort of the goal and "ideal" scenario (ideal given bankruptcy, of course, which in turn is not ideal). In the re

A more sensible strategy is probably to protect only against large down moves, so get OTM puts, and then longer maturities (like 1/2 year or so), then rotate them every quarter. ATM options cost approximately 0.4 S sigma T^0.5 (do a Ta
