A merit of the passive approach is that the act of buying tasty cookies will increase the tasty-cookie price. The passive investors' existing tasty-cookie holdings will increase in value, too.

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).



This is confused

> All the passive investors want is for their cookies (and new-cookie acquisitions) to be properly priced.

No, they want the cookies they purchase to be under-priced, and consumed once their price has gone up. The cookie analogy fails here, but passive investors are exclusively seeking return, not an efficient market.

> No matter what, they have an average distribution of cookie-quality in their holdings.

That's not how passive investing works. The classic model is investment in an index -- say the FTSE 100 -- which attempts instead to maximize the quality of holdings, not the most accurately priced.

> It is hard to bilk a passive investor

Yes, but that doesn't mean it's hard to make money off one.
