Global stock markets climbed on Thursday as strong results from two of the world's biggest technology companies pulled investors back toward artificial intelligence-related shares. Amazon's cloud business showed signs of reaccelerating, while Microsoft's cash flow outlook reassured investors who had grown nervous about the huge spending required to build out AI infrastructure.
The moves helped steady markets that had been jittery in recent weeks over whether the AI trade had run too far, too fast. The renewed enthusiasm for tech names lifted major indices in the US and Europe, with futures pointing higher at the open.
Cloud growth and cash flow ease AI worries
Amazon reported that its cloud computing division, Amazon Web Services, saw a pickup in growth, a key metric for investors because cloud services are seen as a bellwether for corporate tech spending and a major driver of AI-related demand. The acceleration suggests that businesses are still willing to pay for computing power and AI tools, even as some economists warn of a slowdown.
Microsoft, meanwhile, offered a reassuring outlook on cash flow, a critical measure for a company that has been investing heavily in data centers and AI models. Investors have been watching whether the massive capital expenditures required for AI would squeeze returns or strain balance sheets. Microsoft's guidance suggested that the spending is translating into revenue growth, easing those concerns.
The positive signals from both companies helped offset lingering worries about the broader economy, including soft manufacturing data from China and a dip in oil prices. As US stocks steadied earlier in the week, the tech earnings provided a fresh catalyst for buying.
Yen remains volatile after suspected intervention
While equities found support, the Japanese yen stayed on edge. Traders suspect that Japanese authorities intervened in the currency market earlier in the week to prop up the yen, which has been under pressure as the Bank of Japan keeps interest rates ultra-low. The central bank held rates steady at its latest meeting, a decision that did little to change the dynamics that have made the yen one of the weakest major currencies this year.
Intervention—when a government or central bank buys its own currency to support its value—can provide temporary relief, but it rarely changes the underlying forces driving exchange rates. In this case, the wide gap between interest rates in Japan and those in the US and Europe continues to encourage investors to sell yen and buy higher-yielding assets elsewhere.
The yen's swings are worth watching for global investors because they can affect everything from Japanese exporters' profits to the cost of imported goods in Japan. A weaker yen also tends to boost the competitiveness of Japanese companies, which is why the Nikkei 225 has been heading into a busy earnings week with some optimism.
What it means for investors
For everyday investors, the key takeaway is that the AI trade is not dead—it's just becoming more selective. The market is rewarding companies that can show real revenue growth from AI, rather than just promising future potential. Amazon and Microsoft both demonstrated that they can turn AI enthusiasm into actual dollars, which is why their stocks and the broader market rallied.
But the volatility in the yen and the mixed economic data serve as reminders that markets are still fragile. The AI boom has been a major driver of stock gains this year, and any sign that it's fading could trigger sharp pullbacks. That's why investors should focus on the fundamentals of the companies they own, rather than chasing the latest headline.
As the global AI trade cooled in July, some investors rotated into other sectors, but this week's earnings suggest that the core AI names still have momentum. The question now is whether other tech giants can deliver similar results in the coming weeks.
For those with a diversified portfolio, the recent swings are a normal part of market behavior. The best approach is to stay the course, keep a long-term perspective, and avoid making impulsive decisions based on short-term currency moves or single earnings reports.
