In the days of free and easy money, under the leadership of Federal Reserve chief Alan Greenspan (once dubbed the ‘Maestro’, though strangely enough, not any more), investment became a big game of ‘spot the next bubble’.
With hindsight, investing was easy. You just had to ignore things like fundamentals and rationality, and buy whatever everyone else was buying. Trouble was, you also had to avoid being the ‘greatest fool’, and bail out before the bubble popped. Lots of people didn’t, hence the current pain being caused by the property slump.
Losing money in bubbles is painful and teaches a hard lesson. We’ve had two in less than a decade – the tech bubble and then the property bubble. Surely it would be difficult to take investors for a ride again?
Certainly it would be difficult. But not impossible…
As someone who’s studied psychology in the past, I’d be the first to admit that it’s a pretty ‘soft’ science compared to something like physics, for example. But compared to the pseudo-science that passes for economics, it’s positively respectable.
And given that markets are anything but rational (even the Chartered Financial Analyst Institute admits that most of its members have lost faith in the ‘efficient markets hypothesis’), it makes a lot of sense to take investors’ all-too-human characteristics into account when trying to figure out what markets might do next.
In a recent research note, Montier took a look at the psychology of bubbles. As suggested earlier, you’d think that investors would learn. If they’d seen one bubble, they’d be more careful in future.
And in fact, they do learn. An experiment conducted by joint Nobel prize winner Vernon Smith used an investment game where investors could trade a dividend-paying equity under four different random economic conditions, each of which would result in a different dividend payout.
In the first game, investors at first undervalue the equity, then massively overvalue it, creating a bubble which then deflates. Smith then got the same people back to play the game again. What happened? Well, says Montier, “far from learning from their experience in the first round, participants generally go on to create yet another bubble!” And when they were asked why, “the most common response was they thought they could get out before the top this time!”
However, when Smith asked the same players to play a third time, this time they’d learned. “You end up with a much tighter correlation between the market price and fundamental value,” says Montier.
So twice bitten, thrice shy, it seems. And you might therefore expect the current generation of investors to have learned from the two big bubbles of the past decade.
…but they can get sucked into creating them
But that’s not the end of the story. Smith found that there was a way to get experienced investors back into bubble mentality. How?
“A massive liquidity surge” is exactly what the world’s central banks are trying to create just now. Montier says he has no idea if it will be large enough to “reignite a bubble (and of course another crash afterwards).” But as US fund manager Jeremy Grantham of GMO has pointed out previously, we’re currently seeing “the greatest monetary and fiscal stimulus by far in US history”. So if that doesn’t do it, arguably nothing will.
The next big investment bubble
We’re not sure that investors have another bubble in them just yet. But with all that money floating around, it’s eventually going to go somewhere.
The sector has the heavy backing of the government. It has some great stories behind it – solar towers, wave farms and electric cars – all linked together by smart grids, already being hyped as “the energy internet”.
There’s also a genuine infrastructure problem to solve. The laying of internet cables and railway lines bankrupted many people and companies. But those bubbles created the infrastructure necessary to improve our lives and increase productivity and efficiency.
So the conditions are ripe in the alternative energy sector for a bubble.
