Investing In Our Children

Live Long and Prosper

Statistically, a child born today is more likely to reach 100 than someone who is already 96 years old. And this is happening at a time when government resources are increasingly stretched and retirement ages are creeping upwards, when the populations of the developed nations are aging and the borders are increasingly closed to younger people from poorer countries.

As parents the one thing we can do for our children, to prepare them for this dystopian future, is give them the skills they need to survive and, hopefully, prosper. And chief of those skills, in a world dominated by the ideology we call capitalism, is a proper understanding of how to manage money: because the alternative is that money will manage them.

Saving the Appearances (of Standard Finance)


Back in the Europe of the Middle Ages there existed a curiously schizophrenic attitude to the question of whether the Earth was at the center of the universe. The doctrine of the established Catholic Church decreed that it was. The practical evidence suggested that it wasn't and the orthodox scientific theory endeavored to fit the evidence to the theory, at the expense of commonsense and logic.

Today there exists a similarly curious attitude to the question of whether or not economics is governed by people making rational decisions in consistent ways. The doctrine of the established economic theory says that it is. The practical evidence suggest that it isn't. And the orthodox economic theories endeavor to fit the evidence to the theory, at the expense of commonsense and logic.

Quality Plays

Rational Exuberance?

One of the odder financial bubbles we saw in the last century was caused by a bout of temporary insanity in the 1970's over a group of the biggest and best American corporations. The so-called Nifty Fifty were, for a while, promoted as the must have, long term buy and hold stocks. And with a certain pleasing inevitability the stocks soared and then, in strict adherence to the law of financial gravity (and very grave it is, too), plummeted. Another mental meme dashed against the rugged rocks of reality.

Only this story isn’t so simple, because the Nifty Fifty weren’t a bunch of story stocks flung high by the whim of investors’ irrational exuberance. They didn’t just disappear having made their owners very rich and their shareholders poorer, and no wiser. The afterlife of the Nifty Fifty tells us an interesting story about the nature and durability of quality in the stockmarket: quality plays, if you understand the rules of the game.

Facing Down The Narrative Fallacy

Frenzy Time

Markets are tumbling. It's because the Fed is about to push up interest rates. Or maybe because the German economy is weak. Or perhaps it's Ebola, about to decimate global populations. Or it's geopolitical conflict - Ukraine, Syria, Iraq ... take your pick. It's a perfect storm. Head for the hills and don't spare the horses. And remember the shotgun.

Of course, it's none of these. Markets are falling because they were a bit overpriced and investors were ignoring the fact because they'd got themselves into a typical feeding frenzy, ignoring the risk and ambiguity that are always present. Now that they have recognized the issue they're fighting each other to get out the door. Which is why all of the explanations for market weakness are entirely plausible and entirely wrong - they're an example of what Nassim Taleb calls "the narrative fallacy".

Be Humble, Become Wealthy

Thrusting, Decisive and Frequently Wrong

We are both by design and by culture inclined to be anything but humble in our approach to investing. We usually invest on the basis that we're certain that we've picked winners, we sell in the certainty that we can re-invest our capital to make more money elsewhere. We are usually wrong, often extremely wrong.

These tendencies come partially from hard wired biases and partly from emotional responses to the situations we perceive ourselves to be in. But they also arise out of cultural requirements to show ourselves to be decisive and thrusting; we rarely reward those who show caution in the face of uncertainty. But we're private investors, we have limited capital and appetite for risk. A little humility - or even a lot - wouldn't go amiss.

Metaphors We Invest By

Lost for Words

Metaphor is a powerful engine for driving thought. Or possibly it's a useful compass for guiding it. Or perhaps it's some other metaphor. The point is the we tend to think in metaphors, even about metaphor, and it seems that the metaphors we use to describe a situation  determine how we view it and what we do about it.

So companies may be in a tail-spin, or simply marking time. Or perhaps they're in terminal decline, or maybe it's merely a temporary setback. And maybe we're talking about the same thing, and how you hear it described determines your reactions to it ... metaphor is powerful, acts on us unconsciously and is almost completely useless to an intelligent investor.

Bad Behavior: From A to Z ... and Back Again

Talking Shop

A common reaction to pointing out to investors (or indeed, anyone) that they're as biased as a Fox reporter at a convention of transgender liberal pacifists is for them to respond, not unreasonably, by asking what they should do about it (that's the investors, not the reporters). It turns out that it's a lot easier to say what's wrong than to actually do anything about it.

The A to Z of Behavioral Bias is an attempt to address that issue, but it does rather show that there's no such thing as a common source of biases; bad behavior comes from many sources and requires many solutions. Or does it?

Z is for Zero Risk Bias

Zero-risk bias is a preference for options that completely eliminate some risk even where alternative, often cheaper, options will reduce the overall risk by more, proportionately.We often prefer the absolute certainty of a smaller benefit to a larger benefit of less certainty.

Y is for Yawn Effect

The Yawn Effect occurs when you yawn in response to someone else yawning. In fact you can even get your dog to do it (or get coerced into yawning by your pooch). Yawning is contagious, and contagion is an inevitable unconscious consequence of people interacting with each other - and, as usual, when we behave automatically as investors it doesn't make for a good financial outcome.

X is for Xenophobia

OK, Xenophobia isn't really a behavioral bias, but Home Bias is its equivalent - the tendency of investors to favor their home markets over foreign ones and to damage their returns, or at least increase their risks, in the process.
