The Philadelphia Semiconductor Index, known as SOX, has surged 50% in just 25 trading days, reaching 10,000 points as of May 6, 2026. That's the strongest rally since March 9, 2000.
AI memory chip shortages are the primary driver, with hyperscalers, sovereign AI projects, and enterprise customers vying for limited supply, allowing chipmakers to sell at premium prices.
Every stock in the index rose at least 14% during this period. Standouts include Intel, Credo Technology, and Astera Labs, which each posted gains exceeding 100%. Intel's resurgence is tied to its collaboration with Apple. Credo Technology and Astera Labs are capitalizing on data center infrastructure demand.
The rally raises bubble concerns. Macro strategist Marko Kolanovic is reportedly cautious. Investor Michael Burry has purchased protective puts on the iShares Semiconductor ETF. However, bulls point to real corporate budgets and government investments in AI, unlike the dot-com era.
Investors should monitor both Asian and US chipmakers, as each region holds critical supply chain nodes. The Intel-Apple partnership is a key catalyst to watch.
