I joined Angus Randall and Julia Bergin from ABC The world to discuss why, despite artificial intelligence’s (AI’s) enormous long-term promise, early investors often face the highest risks. History shows that major technology advancements usually go through a boom–bust cycle, which is why caution – not blind optimism – is essential right now.

I joined Phil Clark on Nightlife to explain why the market’s sharp fall may reflect growing doubts about the artificial intelligence (AI) boom. I argued that while AI is a powerful General Purpose Technology (GPT) that may change the world (like cars or the internet), it might not be as lucrative as investors hope. Today we’re seeing super-charged share prices, huge data-centre spending, complex vendor-financing deals and big losses at firms like OpenAI. Whether this proves a correction or a bust is unknowable, so my message to investors was simple: regularly rebalance and diversify beyond the AI winners.

On Monday the S&P/ASX 200 tumbled two per cent, led by a sell-off in tech stocks. It’s now down about seven per cent over the past month. Concerns about the end of the interest rate cycle in Australia, a lack of information on Wall Street and the forever present geopolitical fears seem to be weighing on investors.

On Fear & Greed, with Sean Aylmer, I explained that stretched valuations and a cooling of artificial intelligence (AI) optimism are prompting a shift in sentiment – but this isn’t a time to panic. It’s a reminder to rebalance, trim what’s run hard, and look to genuinely diversified, uncorrelated opportunities.

Today on Ausbiz I joined Juliette Saly to discuss why artificial intelligence (AI) remains a powerful long-term thematic but is now exhibiting classic bubble warning signs. We need to question whether the exponential share-prices, circular vendor-financing deals, and the huge capital expenditure (CapEx) that we are seeing today, are sustainable.

While AI will undoubtedly transform the world, the economics underpinning today’s spending frenzy look increasingly stretched, with key leaders unable (or unwilling) to explain how trillion-dollar commitments will be funded. In times like these, disciplined rebalancing is a smart approach.

I joined Niav Owens on ABC Newcastle Mornings yesterday to discuss why cash is making a comeback – despite the rise of digital payments – and why it still plays an important role in budgeting, privacy, and accessibility. We also touched on the trillions being poured into artificial intelligence and whether those investments can truly deliver the returns investors expect.

Not only are stock market valuations stretched, but on the metrics that are most reliable for predicting future returns, the U.S. market is at an all-time high. We can say that factually and therefore categorically.  It’s not a matter of opinion. 

It’s worth remembering to bring everything back to the data to avoid the influence of emotions. 

The important question then is not whether reducing your exposure and rebalancing portfolios results in a missed opportunity to maximise gains, but whether you’ll regret not doing that, and instead of retiring in two years, being forced to work for another six or seven. Indeed, and upon reflection, there will always be regret; the decision is about which regret is worse. Letting gains evaporate might be worse than missing out on a few more dollars.

Since my last column Is there a stock market bubble? Here are the warning signs, which was on the topic of recognising bubbles, subtle shifts have been occurring in the risk postures of major global investors that suggest you now need to behave more cautiously than before.

Some of those behaviours have been reflected in the relative outperformance over the last month of defensive sectors such as healthcare and utilities, beating technology, artificial intelligence (AI) and defence. And some of the same behaviours also reflect the changing picture of liquidity, which, of course, is the fuel that inspires all thematically driven rallies.

Yesterday I joined Jess Maguire on ABC’s Statewide Drive to discuss the sharp fall in Meta’s share price after it revealed another huge increase in artificial intelligence (AI) spending. I explained that while Mark Zuckerberg insists the investment will eventually pay off, the scale of AI infrastructure costs – potentially US$3–5 trillion by 2030 – means companies will need extraordinary revenues to justify the outlay. History shows transformative technologies often enrich consumers more than investors, and while today’s firms are profitable – unlike in 1999 – the “build-now, profit-later” mentality risks colliding with commercial reality.

Today on Ausbiz I joined Sue Lannin to discuss the striking similarities between the 2011 iron ore boom and today’s artificial intelligence (AI) investment frenzy. Back then, surging optimism and over-investment in mining services ended abruptly when supply outstripped demand. I’m seeing echoes of that now in AI, with forecasts of trillions in annual spending that don’t appear sustainable or supported by realistic revenue. With companies like Meta and Microsoft already under pressure, I believe we’re nearing the end of this boom as investors start questioning whether the numbers truly add up.

I joined Paul Turton on ABC Newcastle Mornings yesterday to discuss how markets remain strong but expensive, with investors shifting from artificial intelligence (AI) stocks to safer sectors like healthcare and utilities. Despite record highs, valuations suggest future returns may be lower. I explained that while a correction isn’t inevitable, there are promising opportunities in smaller, innovative companies that are starting to outperform larger ones.
