Monkey Investors

Just a few weeks ago I wrote a post about the Wall Street Monkey. Remember that the story was based on Burton G. Malkiel’s book, “A Random Walk Down Wall Street”, where he suggested that a blindfolded monkey throwing darts to select stocks wouldn’t do worse than professional fund managers.

I watched yesterday TED Talk by Laurie Santos, “A monkey economy as irrational as ours”, where she explains how she studied whether our mistakes were due to a badly designed environment or badly designed minds.

She made several studies with apes, introducing the use of money to them… and she found that apes show the same irrational behaviours regarding risk taking as we humans do…

I loved especially the following passage around minute 16:30…

“… we can actually give the monkeys a financial currency and they do very similar things we do. They do some of the smart things we do, some of the kind of not so nice things we do like stealing and so on… but they also do some of the irrational things we do; they systematically get things wrong and in the same ways that we do.

This is the first take-on message of the top… if you saw the beginning of this and you thought: “…oh! until I go home and hire and put a monkey as financial advisor … they were cuter than ours…”, don’t do that: they’re probably gonna be just as dumb as the human one you already have!

At least, apes would charge us less… just a couple of grapes.
