The NASDAQ Composite tracks over 3,000 stocks listed on the NASDAQ exchange. It is heavily weighted toward technology and growth companies, making it the go-to benchmark for the tech sector.

Why It Matters

The NASDAQ Composite is dominated by mega-cap technology companies—Apple, Microsoft, Nvidia, Amazon, Meta, Alphabet, and Tesla collectively represent a massive portion of the index. Its performance reflects the health of the technology sector and growth investing.

Growth vs. Value Barometer

The relative performance of the NASDAQ vs. the Dow Jones often reflects the rotation between growth and value investing styles. When NASDAQ outperforms, growth/tech is favored; when it underperforms, value/cyclical stocks are in demand.

Market Impact

The NASDAQ tends to be more volatile than the S&P 500 or Dow due to its growth-stock concentration. It is particularly sensitive to interest rate expectations—rising rates increase discount rates applied to future earnings, pressuring high-growth tech valuations.
