After Friday's market meltdown, which
was sparked by growing concerns about the reliability of AI projections, as well as the news that Google's search business was under attack - from its own AI service - there has, again been increasing attention on the issue of earnings concentration.
But investors seem to believe that risk is priced into the market already and that it is no longer a stealth or surprise threat. The larger question remains whether AI's financial and operational benefits can break out across the economy at scale. JL
Hannah Lang reports in the Wall Street Journal:
The boom is being driven by just 10 companies which account for two thirds of corporate profit growth. Micron and Nvidia alone account for a third of the earnings growth. If you take out those 10 all stars, the earnings growth for the S&P 500 for the third quarter drops from 30% to 10%. This is just one more way in which the stock market has come to depend heavily on the massive bet on AI; that the productivity gains and money-making ability of AI will be worth the hundreds of billions of dollars being spent. As soon as Wall Street starts to question that belief it can lead to violent shifts in the market. So the risk posed by concentrated earnings growth is the same risk underpinning the broader AI investing boom, that the technology won't be able to deliver on the massive sums US companies are pouring into it.
