US tech giants are holding back the S&P 500 from hitting a record high, reversing the role the industry has occupied for the last 18 months as the main pillar supporting the US blue-chip benchmark.
After a weak US jobs report jolted global markets at the start of the month, the S&P has quickly clawed back the bulk of its losses. It was up 1 per cent on Friday, closing just 21 points short of the record high set in mid-July.
But it has struggled to make the final push over that line, even as the majority of stocks in the index have advanced since coming within touching distance of a new high more than week ago.
The inability to get over the hurdle is largely down to the lowly performance of the Silicon Valley tech groups that were in highest demand in the first half of the year.
“It’s the reverse of what was happening earlier,” said Kevin Gordon, senior investment strategist at Schwab. “You’re being weighed down by some of the mega-caps . . . [and] it wouldn’t surprise me to see that dynamic continue.”
Almost 70 per cent of companies in the S&P 500 have risen since the index peaked on July 16, according to Bloomberg data. If every company in the S&P were weighted equally, the index would have been back at a record by August 23.
But tech and communication services have an outsized weighting on the S&P, accounting for around 40 per cent of the total, even with Amazon and Tesla categorised as consumer groups.
Instead, their sluggish returns since July are turning into an anchor. Sixteen of the 20 biggest drags on the S&P 500 since its last record were tech groups, led lower by six of the so-called “Magnificent Seven” — Microsoft, Amazon, Alphabet, Tesla, Apple and Nvidia.
The exception is Meta, which has risen since mid-July but is still down 4 per cent from its peak. Chipmakers and their suppliers like Broadcom, Qualcomm, AMD and Applied Materials were among the other major drags.
Their leaden returns since July stand in sharp contrast to 2023 and the first half of this year, when enthusiasm over the potential of artificial intelligence fuelled a massive rally in semiconductor stocks and other large tech groups predicted to be early AI beneficiaries.
For most of them, there has been no sudden downturn in corporate performance, but the extent of the rally had prompted widespread debate over whether stock prices were simply too high.
Bloomberg’s Magnificent Seven index has fallen 10 per cent from its early July peak, but the decline has been even steeper on a price to earnings basis. It was this week trading at around 33 times expected earnings over the next 12 months, still higher than the broader S&P 500 but down 13 per cent since the peak.
Investors have been holding big tech groups to a high standard during the latest quarterly earnings season, with many of them punished even after publishing strong results.
Nvidia, which single-handedly drove more than a quarter of the S&P’s advance in the first half, fell 6 per cent on Thursday despite reporting stronger than forecast results. Alphabet and Microsoft had similarly negative responses to solid results.
In contrast, the equal-weighted S&P 500 is trading at its most expensive level since February on a price-to-earnings basis. Smaller companies and more cyclical sectors have been boosted by reassuring economic data, positive earnings reports and encouraging comments from Federal Reserve chair Jay Powell, who declared at the annual Jackson Hole economic symposium that “the time has come” for the US central bank to begin cutting interest rates.
“One of the bigger themes over the next year is going to be a broadening of the market,” said Francis Gannon, co-chief investment officer at Royce Investment Partners, which specialises in small-cap investing. “It usually begins in fits and starts . . . but I think we’re on our way.”
The Russell 2000 index of smaller companies is up 8 per cent so far this quarter, compared with a 3 per cent increase in the S&P 500. Within the S&P 500, the best-performing areas have been rate-sensitive sectors like real estate, utilities and financials.
The debate over tech is still far from settled, however. Schwab’s Gordon said many investors had become “exhausted” by the AI trade, but stressed that even after a “necessary and understandable catch-up” for other sectors, tech was still by far the best-performing sector of the year to date.
And despite the recent resilient data, US economic growth is still slowing, which could put pressure on the rest of the market later in the year.
“There is more downside risk,” said Drew Matus, chief market strategist at MetLife Investment Management, highlighting falling consumer savings and rising unemployment. “And if the Fed cuts as aggressively as the market is currently pricing in, [it would mean] nothing good is happening in the economy.”
Sebastien Page, head of global multi-asset and chief investment officer at T Rowe Price, said “we’re having more debates between the bulls and bears than we usually do in our committee.
“Rates are coming down and earnings are powering through this slower economic environment . . . [but] we’re back to fairly expensive markets.”
Page said that in the short term his division’s funds were positioned for a further outperformance in value stocks, but said “we still like a lot of the big tech companies” and could switch if tech becomes oversold.
“Expectations are very high for technology, but it is not the tech bubble,” he added.
For many active investors, a broadening out of gains away from the largest names would be a welcome change, even if it made it less likely to see big rises at the level of the headline index.
For true believers in the potential of AI, however, a slight pullback has not shaken their faith.
“We have all this discussion about ‘bubble bubble bubble’, [but] valuations are nothing like they were in 2000 or even 2021,” said Tony Kim, head of technology investing in BlackRock’s fundamental equities division.
“We’re in the second year of a complete replatforming of the whole tech industry to this new thing called AI, and I think we’ve barely started.”
