@shevaxgod worth being precise: time weighted removes the effect of flows on purpose, so the manager is judged on decisions rather than on when clients panicked. both numbers are honest. they answer different questions.

[Luke Foster @Lukeffost]

@AlgoKavya 18% of the stocks in the simulation died.

none of them appear in a list you pull today.

[Luke Foster @Lukeffost]

@dylanquantt so what, everyone should become a market timer now?

[Luke Foster @Lukeffost]

@dylanquantt they cancelled trades more than 60% away. so the market decides afterwards what was real

[Luke Foster @Lukeffost]

@shevaxgod this is the coke post inverted. there the payment arrived forever, here it arrived once.

[Luke Foster @Lukeffost]

@shevaxgod he went to a restaurant instead of a spreadsheet. thirty years of business school has not improved on that.

[Luke Foster @Lukeffost]

@AlgoKavya the next time someone shows you 12 green months, ask how many versions they ran before that one.

[Luke Foster @Lukeffost]

@dylanquantt credit suisse never really recovered from this one

[Luke Foster @Lukeffost]

@vivaanix At what drawdown would you quit a strategy you still believe in

[Luke Foster @Lukeffost]

@shevaxgod $19.4 million to $173 billion. the compounding of the funding source, not of the portfolio.

[Luke Foster @Lukeffost]

@shevaxgod everyone copies the stock picks and nobody can copy the funding. that's why there's one berkshire.

[Luke Foster @Lukeffost]

@shevaxgod five million dollars between the best purchase of his career and never owning it. he's said he'd have walked.

[Luke Foster @Lukeffost]

@shevaxgod revenue up nearly five times and the stock took twenty five years to get back to flat. those two facts in one company is the whole education.

[Luke Foster @Lukeffost]

@AlgoKavya every trade has a buyer and a seller in identical size.

whatever delta is measuring, it isn't who accumulated.
