Imagine there was a cookie market made up of two types of cookies, tasty and meh. An active investor in cookies would spend time determining which cookies are likely tasty and which are meh. They would pay more for the tastier cookies so they can savor the flavor and less for the meh ones they can binge eat in the shower when no one is home.... A passive investor comes along and says, I don't want to do all this rese…
> At some point, no one is left to figure out which cookies are tasty vs meh Except that there’s a lot of money to be made by figuring out which cookies are winners, and buying them cheaply to sell to the passive investors.
All the passive investors want is for their cookies (and new-cookie acquisitions) to be properly priced. No matter what, they have an average distribution of cookie-quality in their holdings.
The passive investors are not buying cookies at any price other than the market price. Whatever the clever-cookie-buyer is paying for cookies, they're paying the same. If a clever-cookie-buyer buys low, takes out an ad in Cookie Magazine, and sells high to a bunch of tasty-cookie aficionados, the passive investors win, too. If a too-clever-cookie buyer buys low and discovers that the apparently-tasty cookies have spoiled, the passive investors lose a little, too.
It is hard to bilk a passive investor. The first people to really figure out how will accumulate a lot of money (and ire).
