Marks argues the key insight is that any asset can be good at the right price.
“the big realization of the last ten, forty years is that just about every asset can get cheap enough so that it's a good investment, and most investments can get so expensive that they're a bad investment. And the revolution of the high yield bond industry was really to say,”
Marks states good investing is not buying good things but buying things well; price determines risk.
“it's not what you buy, it's what you pay that determines whether your investment is risky or not. B, that good investing is not a matter of buying good things, but buying things well.”
Marks states nothing is a good idea in the absence of price, lesson from Nifty Fifty experience.
“But the lesson I learned from my experience with the nifty 50 in '69 was that it's not what you buy, it's what you pay that matters.”
