Can Tech Keep Carrying the Stock Market?

Sep 24, 2026 · 17m

Summary

David Keller of Sierra Alpha Research discusses the bearish divergence between the Nasdaq’s all-time highs and the underperformance of transportation and financial sectors. He explains how Dow Theory highlights this weakness, attributing it to high diesel prices and a flattening yield curve that hinders bank profitability. Keller argues that without broader market participation from these lagging groups, the current tech-led rally lacks sustainability. He suggests monitoring breadth indicators for signs of accumulation, projecting a potential Nasdaq top near 30,000 before a broader correction.
