This 100-Year-Old Theory Says the Stock Market Isn’t Done Climbing: Ed Yardeni

Jul 27, 2026, 2:03 PM UTC · Primary ticker $IYT

Ed Yardeni argues that Dow Theory, a century-old market indicator, remains bullish, with both the Dow Jones Industrial Average and Dow Jones Transportation Average in record-high territory. He attributes the strength in transportation stocks to the indirect benefits of the AI infrastructure buildout, as these companies haul materials for new data centers.

This filing highlights Ed Yardeni's analysis that the Dow Theory, a historical market indicator, is signaling continued bullishness. This matters because it provides a counter-narrative to concerns about AI spending's impact on tech giants, suggesting a broader economic benefit. Transportation companies (like those in IYT) are directly affected positively as they haul materials for AI data centers, leading to increased revenue forecasts. While tech companies like Alphabet and Tesla face scrutiny over free cash flow, Yardeni argues the capital is simply flowing to other sectors. Short-term, this could encourage investment in industrial and transportation sectors; long-term, it suggests a more robust and diversified economic impact from AI. A key risk is the high valuation of transportation stocks and potential pressure from rising oil prices.
