Chipmakers head for big profit gains, but will it be enough?

Chipmaker shares are experiencing significant price swings on Wall Street this month. Investors anticipate these companies will drive much of the S&P 500's profit growth. Recent earnings reports have shown strong results but market reactions have been mixed. Concerns about artificial intelligence demand sustainability are fueling investor reassessment of the sector. Leveraged exchange-traded funds are also contributing to the increased market volatility.
