The second quarter US earnings season saw earnings per share (EPS) growth hitting 52% – the highest level since the post-Covid recovery of 2021 – with only one underlying sector in the S&P 500 Index of US companies (healthcare) failing to report earnings growth. In all, 85% of S&P 500 companies beat expectations, helping US corporate profits to hit $4.8trn in the second quarter. This was a record share of national income (18%) and follows the $4.42trn total profits in the first quarter.
Within this, Alphabet (Google), Amazon, Nvidia and Microsoft also booked an additional $160bn of gains on their stakes in OpenAI, Anthropic and SpaceX. This helped to bring ‘blended’ earnings growth (which combines actual results with forecasts for those yet to report) for the technology sector to 75.3%. Meanwhile, the ‘Magnificent 7’ cohort of technology mega-caps enjoyed earnings growth of 118.5%, thanks to their additional AI investments.
Consequently, Alphabet’s results pushed earnings growth in the communication services sector to 116.9% while Amazon’s numbers took EPS growth in the consumer discretionary sector to 92.4%.
Meanwhile, US banks flourished, thanks to record IPO and AI-related trading receipts, while energy and defence stocks advanced on the back of the Iran war.
US inflation steps down in June and July
Reported US inflation continued to ease in July and August. Mid-July saw two US inflation surprises that helped both stock and bond markets to rally. First, June’s annual Consumer Price Index (CPI) reading came in at 3.5%, sharply down from May’s 4.2% driven by painfully high gas prices, and well below the 3.9% forecast. June saw monthly CPI enjoy its biggest decline since 2020, thanks to an almost 10% drop in gas prices at the pumps. Meanwhile, core inflation, which strips out volatile food and energy costs, dropped from 2.9% in May to 2.6% in June.
A day later, the same fall in energy prices helped Producer Price Index (PPI) inflation, also known as ‘factory gate inflation’, to its biggest monthly drop in over a year. Wholesale costs fell 0.3% in June (although this was subsequently revised to 0.1%) while core PPI rose by less than expected (0.2%), taking annual PPI to 5.5%.
A month later, US CPI declined to 3.4% in July with core inflation easing to 2.5% while US PPI remained flat. The news helped the S&P 500 Index hit another record high.
Treasury intervention and the ‘debasement trade’
After a gruelling climb in US Treasury (government bond) yields that took the yield on 30-year bonds to a 19-year high (5.31%), meaning that prices were at record lows, mid-August saw Treasury secretary Scott Bessent announce that the Treasury would intervene in the US bond markets.
He announced a plan to “at least double” its buyback operations for longer-dated government bonds (from $2bn to $4bn), removing less liquid issues from circulation. This provided a temporary boost to stock and bond markets, and helped Treasury yields to ease, but they subsequently reversed course to give up these gains.
The news that the US Treasury felt it necessary to intervene triggered a powerful rally in commodities and alternative assets as investors looked to move away from the US dollar and dollar-denominated assets in what’s referred to as a ‘debasement trade’. Gold jumped over 4% on the day of the announcement, on the way to its third best month of the 21st century with gains of over 12% that took the yellow metal back into positive territory for 2026.
Other precious metals also rallied as did metal mining stocks and crypto currencies as investors sought alternatives to dollar exposure.
Our chart of the month
What this chart tells us
Although the words ‘this time it’s different’ are among those most mistrusted by professional investors, it’s clear that the current boom in US technology stocks has little in common with the dot-com boom of a quarter century ago. This time around, a completely different technology is driving markets higher, creating an entirely different picture.
As the chart illustrates, back in 1998 and 1999, the valuations for technology stocks in the S&P 500 Index came unmoored from their earnings, rising almost vertically on the promise of stellar future returns from a newly-arrived internet that was still in its infancy. As the black line shows, these earnings never materialised in anything like the timescales imagined at the time.
By contrast, the current ‘bull market’ in technology stocks is being driven by persistent earnings growth from companies exposed to the AI buildout theme. Technology stocks at every stage of the supply chain are benefiting from a steep increase in hardware sales with investment into information processing equipment up over 30% in the year to the end of June 2026.
The value of such investment has now surged to 2.45% of US GDP – its highest share of the US economy in over 20 years.
