Stocks had a strong third quarter, following a solid second quarter. In fact, the market hit new all-time highs for both the S&P 500 and the NASDAQ 100, driven mainly by mega-cap technology stocks, especially NVIDIA. However, as we move into the fourth quarter, there are signs that investors may be becoming cautious of the heavy spending by some of these mega-cap companies, as seen in their increasing CapEx numbers. This could potentially cause a negative shift in market sentiment toward these stocks.
