If the "total market cap of this economy" includes cash, then it wouldn't change if people "sell" cash to buy stocks, or vice versa, right? As I said, the assumption in this thought exercise is that money sloshes around between the four assets, meaning the total amount of money sloshing around remains constant.Kriegsspiel wrote: ↑Fri Jun 01, 2018 8:52 pmWell If, for instance, all assets were worth $25, and everyone wanted to sell stocks, they'd keep dropping in value until someone felt like buying them. If nobody wanted to buy them until they were at $5, then the total market cap of this economy would be $80. So some money went from, say, cash to stocks, but $20 of value is gone.Tortoise wrote: ↑Fri Jun 01, 2018 7:38 pm Has anybody here ever compared the total market capitalization of stocks, LTTs, gold, and cash?
If we assume that money "sloshes" between those four assets -- i.e., that if it flows out of one, a roughly equal amount must flow into one or more of the others -- then the portfolio would maintain a constant value only if the four assets were allocated according to total market capitalization, right?
It would be interesting to see those four percentages...
I'm not claiming the assumption is necessarily realistic, but it does seem to be implicit in some discussions about the PP concept. The idea seems to be that money has to go somewhere, and if you're invested in stocks, bonds, and gold, it's probably flowing into at least one of your assets -- unless it's one of those nasty beasts known as a "tight-money recession" where money disappears into a black hole
