AI trade frenzy seems driven by a 'virtuous' cycle

Investors who bet against the S&P 500 in October were caught off guard as the index rose by 2.3%, defying the historical trend often referred to as "Octoberphobia." This term has emerged due to significant market downturns that have occurred in October, notably in 1929 and 1987. The Nasdaq Composite performed even better, with a remarkable increase of 4.7%, largely fueled by the booming technology sector. A notable highlight was Amazon's stock, which jumped 9.6% following impressive growth in its cloud-computing division. CEO Andy Jassy emphasized the strong demand for artificial intelligence and core infrastructure, a sentiment that also benefited other AI-related stocks like Palantir and Oracle. This surge in AI stocks reflects a broader trend rather than a fleeting moment of excitement. Nvidia, a leading name in AI, achieved a historic milestone by becoming the first company to reach a valuation of $5 trillion. CEO Jensen Huang articulated a concept he termed a "virtuous cycle," whereby increased usage of AI drives further investment, enhancing the technology and, in turn, increasing its adoption. This cycle appears to be gaining momentum as major tech companies recently disclosed significant hikes in capital expenditures, much of which is anticipated to be allocated towards AI infrastructure. In contrast to the temporary highs and lows associated with quick gains, the current enthusiasm for AI seems to resemble a steady energy boost rather than a short-lived spike. Berkshire Hathaway's operating profit also saw a noteworthy 34% year-on-year increase, reaching $13.485 billion in the third quarter, while the conglomerate holds a record $381.6 billion in cash, although stock buybacks are not in the immediate plans. On the geopolitical front, Nvidia's CEO downplayed concerns regarding chip exports to China, suggesting that Beijing's restrictions on certain chips indicate its confidence in its own AI capabilities. Meanwhile, the situation with Nexperia, a chip manufacturer recently taken over by the Netherlands, appears to be easing, as reports indicate that China may lift its export ban. With U.S. markets closing positively last Friday, the S&P 500 starts November significantly up for the year, and investors are encouraged to stay alert for upcoming earnings reports and legal developments concerning tariffs. As tech giants ramp up their investments in AI, their digital advertising revenues are also on the rise, helping to mitigate earlier concerns about economic impacts on ad budgets.
