BofA’s Hartnett Says Real Rates Not High Enough to Pop AI Bubble

The frenzy over artificial intelligence-linked stocks has gone too far but won’t die down just yet, according to Bank of America Corp. strategists led by Michael Hartnett.

The excitement around the technology’s potential has ignited a rally in the likes of Nvidia Corp. and Microsoft Corp., driving first-half gains in the S&P 500. While real rates — nominal interest rates minus the rate of inflation — are too low to pop what Hartnett called the AI “baby bubble,” tighter financial conditions will be a challenge for risk assets in August, he wrote in a note.

Global markets from Treasuries to oil, Bitcoin and stocks have turned into a “world of overshoots” in the 2020s, according to Hartnett, describing these swings in asset prices as “the new normal.” AI is “simply the new overshoot,” he said.

After the blistering gains in AI stocks, the focus, for now, is on the technology’s impact on corporate bottom lines, with the earnings season painting a mixed picture. Analysts said Microsoft’s results failed to live up to lofty hopes about an immediate boost from AI. Meta Platforms Inc., on the other hand, soared after AI helped it improve the efficiency of advertising. Nvidia, Wall Street’s top pick for the AI trade, reports later in August.
