Yes. Exactly. A system where ordinary savers have to be reliant on the success of vehicles that make the very rich richer, and so tolerate a politics that rigs things to transfer wealth to the very rich so they can get their small piece of the action, is a pretty bad system.

i mean, sure? if profiting from active investing is harder, we can always spim that as we’ve upped the skills required to earn the same compensation, rather than that we’ve diminished compensation. 1/

think of it this way: active investors face two distinct challenges. first, they have to gain an informational edge. next they have to exploit that edge at some scale, in markets literally built for price discovery. 1/

when an active investor buys, she does not celebrate if the price goes up immediately. she wants minimal to no to even negative price movement, so she has continuing opportunity to exploit. 2/

what constrains her ability to profit is not lack of liquidity or access to leverage, but the speed with which price usually converges to relative value. 3/

i think you’re overstating the effect of flow on prices. there’s an asymmetry. flow has a stronger effect when a stock is undervalued than when it is fairly or overvalued (relative to peers, in absolute terms they’re all overvalued). 1/

in reply to this

when a stock is (relatively) overvalued, flow induces counterflow with little price change. when a stock might be undervalued, you have to pay up more to compel sellers. 2/

this is why exploiting information is hard. once the market sniffs any interest, you’re not likely to stay so uniquely informed for long. you want to buy silently, have as little move per flow you provide as possible. but if you screw up a little, here come the passive flows. 3/

i certainly object to making a decent retirement contingent on capital allocation institutions most people ought not need to participate in. for people who choose to participate, my objection is to private diversification more than delegation.

so it’s quite different from private leverage, which might fund trades by which they’d try to accumulate positions with as little price effect as possible. this “leverage” erases the opportunities it funds. 3/

in other words, we politically lock in a socially destructive racket that makes the rich much richer by arranging things so that ordinary people can’t keep their heads above water unless the rich earn much much more. yes, exactly. we need to undo all of that.

i guess you’ll have to unpack what you mean by free leverage? index flows might, as a second order effect, make it easier for firms to borrow, as they appear more solvent than they otherwise might. firms can take advantage of high valuations via obfuscated issuance, eg options compensation, mergers.

whether a CD or an index fund, you’re just deferring consumption. the index fund overpays and undermines what might once have been institutions of meaningful capital allocation. the CD does neither (as long as we don’t set risk-free rates too high). /fin

they don’t go anywhere. buying those vehicles rather than spending is disinflationary, leaving more economic headroom for public spending, or if we prefer sector activity, lower rates, and more industrial policy by subsidy.

the answer would be to impose limits to the complexity and scale of investment funds, and to portfolio diversification. if you want safety, buy savings bonds. if you want returns, invest wisely or bear losses. 1/

you can argue that index investors are compensating for bearing undiversifiable macro risk, and that’s a contribution. it’s the best case you can make for the practice from a social, rather than private, perspective! 2/

except upspiraling valuations and obvious policy stabilization undo that case. if policy (to stabilize employment, they of course will say) targets continuing appreciation and ensures downswings are short, then funds holders aren’t making that contribution. 3/

there’s lots you can do be said for social arrangements under which baseline ordinary living doesn’t require personal savings. nevertheless, even if, people do want to arrange the timing of their consumption in ways that deviate from their timing of income. 1/

it might well be that “real” credit-risk-free interest rates should be zero or negative much of the time. sometimes, because of a big social project (think war bonds, but for something good), we may wish to pay up a bit for people willing to defer consumption. 2/

arguably they’ve paid too much, but we as a polity can make what choices we want about what compensation should be (probably negative during recessions!) for merely deferring consumption. /fin
