AI, investment hype and the discipline of not getting carried away

09 Jul AI, investment hype and the discipline of not getting carried away

Artificial intelligence (AI) may become one of the most important technological developments of our lifetime.

It could change how companies operate, how services are delivered, how information is processed and how entire industries are organised.

So this is not an article arguing that AI is nonsense.

It isn’t.

The better question is this:

Can a transformative technology still become an overheated investment theme?

History suggests it can.

Railways changed the world. So did electricity, telecoms, the internet and mobile phones. In each case, the technology mattered. In each case, large amounts of capital chased the opportunity. And in each case, investors eventually discovered that a brilliant future does not automatically justify any price today.

That distinction matters.

There is a difference between asking:

Will this technology change the world?

and asking:

Will this investment produce a good return from today’s price?

Those are not the same question.

A company can be right about the future and still prove to be a poor investment if too much optimism is already reflected in the price. An industry can grow rapidly while many of the businesses within it struggle to generate attractive long-term returns.

We saw this during the dotcom boom.

Many of the broad predictions about the internet proved correct. The internet did change the world. Yet many investors still lost money because prices, expectations and capital spending ran too far ahead of reality.

The lesson is not to avoid innovation.

The lesson is to avoid abandoning judgment.

That is especially important when a theme becomes dominant. Rising prices create confidence. Confidence attracts more money. More money pushes prices higher. Eventually, caution can start to look old-fashioned.

But investing has a habit of punishing people who confuse popularity with permanence.

At Just Us, we are not trying to predict every short-term market move. Nor do we think sensible investing means being cynical about every new development.

Progress matters. Innovation matters. Economic change matters.

But price matters too.

Good investing is not about chasing the most exciting story. It is about understanding what you own, why you own it, what expectations are already reflected in the price and how that investment fits into a wider plan, as investing can help your money grow over time, but the value of investments can go down as well as up.

AI may be here to stay.

But that does not remove the need for diversification, valuation discipline, patience and proper financial planning.

New technology can change the world.

Old investment lessons still apply.

And that is usually worth remembering.
