The stock-market rally keeps spreading beyond Big Tech. October inflation data could put it to the test.

The stock market's upward trend is broadening beyond the traditional dominance of Big Tech, with gains now seen across various sectors. This shift may face scrutiny as October's inflation data and a series of Federal Reserve speeches could influence investor sentiment. The resilience of this diversification is crucial because it suggests a more balanced economic recovery, potentially reducing the risks tied to over-reliance on a few high-growth tech companies. These developments underscore the market's evolving dynamics and the importance of inflation and Fed policy in shaping future market trends.
