Weekend reading: Fama and fortune


What caught my eye this week.

Back when passive investing first began to make serious inroads into the active investing orthodoxy – say 20 years ago – its adherents could be testy.

With none of the amiable grace of Vanguard founder Jack Bogle – whose own son runs an active fund – some passivistas would shout down, sneer at, or stonewall any signs of opposition to their creed.

I suppose it was defensiveness.

Now that even a Sunday newspaper will tell you to buy an S&P 500 tracker, it’s hard to recall when investing in index funds was a fringe pursuit. Something best left to people of low ambition and little intelligence, who’d rather a witless robot picked stocks and who’d prefer to run into the buzzsaw of the Dotcom crash than make a few ‘easy’ decisions to get superior returns.

Actually, when I put it that way then, yeah – the active investing diehards could be just as annoying, too!

I remember the balancing act required in moderating comments on this blog. As a person who loves investing in all its stripes – and who picks stocks as much for sport as the hope of a serious return – I never vibed with this ‘with us or against us’ attitude that some readers lent into.

Here’s the evidence, make your own mind up – that’s been my approach.

Passive is almost certainly the best and easiest way for you to achieve your returns. But you do you.

All in it together

Things have calmed down in the last few years. Surely because index investing is no longer an underdog.

Indeed at the end of 2023, passive funds in the US actually overtook active funds in terms of assets under management for the first time.

The rest of the world is close behind, and the direction of travel is clear.

A good few of us still enjoy investing in companies directly or tilting our mostly-indexed portfolios with side bets (and come join us on Moguls if that’s you).

But I honestly can’t remember the last time an arrogant commenter turned up on Monevator calling all index investors complacent idiots. It was years ago.

You do still sometimes see that attitude elsewhere – on hives of S&V like the ADVFN bulletin boards, say.

However I’d suggest the majority of smart retail investors now understand the strong argument for passive investing in index funds – however they run their own money.

The price is right

Even Eugene Fama seems to have taken a chill pill.

The Chicago economist – whose 1965 paper Random Walks in Stock Market Prices underpinned the intellectual case for the first index funds that arrived a few years later – told the Financial Times this week: “Efficient markets is a hypothesis. It’s not reality.”

The FT says:

Fama is surprisingly phlegmatic when it comes to defending his life’s work, echoing the famous British statistician George Box’s observation that all models are wrong, but some are useful. The efficient market hypothesis is just “a model”, Fama stresses. “It’s got to be wrong to some extent.”

“The question is whether it is efficient for your purpose. And for almost every investor I know, the answer to that is yes. They’re not going to be able to beat the market so they might as well behave as if the prices are right,” he argues.

Fama also makes a good point when he admits to some regrets about choosing the word ‘efficient’ to describe markets.

‘Efficient’ sticks in the craw of those who’ve through bubbles and crashes and who struggles afterwards to see an intelligently discounting market at work.

Easy now! You don’t need to revive the old fighting spirit to shout at me. I understand boom and bust is not incompatible with efficient markets. I’m just saying many people do struggle with the concept.

Anyway Fama has the best rejoinder…

“If prices are obviously wrong then you should be rich,” he says.

Have a great weekend.
