Ausbiz – Is there an AI bubble?
I joined Nadine Blayney on Ausbiz today to discuss why I remain cautious on the artificial intelligence (AI) investment theme, despite strong earnings from the major technology companies. While reported profits continue to rise, I argued that much of the spending on AI infrastructure is being treated as capital expenditure rather than an expense, making earnings appear stronger than underlying cash flows. I also suggested that today’s relatively modest price-to-earnings (P/E) ratios may not tell the full story, noting that markets can still suffer significant declines even from low valuations if earnings prove unsustainable. Ultimately, I believe the key risk is not that AI share prices are too high, but that investor expectations for future earnings may be too optimistic.
