Samsung Electronics Co LtdShares fell 7.9% as markets questioned how long AI-infrastructure spending and elevated memory-chip pricing can persist, despite strong preliminary Q2 results.

The stock market’s focus has shifted decisively from oil-price spikes and Middle East tensions to the artificial-intelligence capital cycle as second-quarter earnings season begins. MFS Investment Management global investment strategist Rob Almeida said attention has moved toward structural forces like the AI buildout, which is one of the largest corporate investment cycles in modern history and is pulling capital toward the physical economy. The S&P 500 Semiconductors & Semiconductor Equipment Industry Group Index returned 109% from the end of 2024 through May 2026, but profit-taking and rotation into cyclical sectors such as industrials, financials, and healthcare have recently confirmed the bull market, according to Baird investment strategist Ross Mayfield. Samsung Electronics’ preliminary second-quarter results showed sales more than doubled and profits rose over 19-fold year-over-year, yet shares fell 7.9% as markets questioned how long AI-infrastructure spending and elevated memory-chip pricing can persist. U.S. Bank Asset Management Group senior investment director Bill Northey said inflation, earnings, and interest rates will determine whether current valuations remain justified, while Mayfield noted that the U.S. is far less vulnerable to oil-supply shocks than in the 1970s, with crude back to $71 a barrel after spiking above $119 in March.
