1. What Is the Nasdaq-100?
The Nasdaq-100 is a modified capitalization-weighted index, meaning larger companies have more influence on the index's performance. It excludes financial companies (banks, insurance companies, etc.), which distinguishes it from broader market indices.
Key characteristics:
- Composition: 100 of the largest non-financial companies on Nasdaq
- Weighting: Modified market-cap weighted (with caps to prevent excessive concentration)
- Rebalancing: Quarterly, with annual reconstitution
- Sectors: Primarily technology, but also includes consumer discretionary, healthcare, and others
2. Common Technical Analysis Concepts
Many investors and traders study charts using technical analysis. Below are some commonly discussed concepts. Note: Technical analysis is one of many approaches to studying markets, and there is ongoing debate about its effectiveness. These descriptions are for educational purposes only.
- Moving Averages: Calculate the average price over a specific period. The 50-day and 200-day moving averages are frequently referenced in financial media.
- Relative Strength Index (RSI): A momentum indicator that measures the speed and magnitude of price changes. Values range from 0 to 100.
- Support and Resistance: Price levels where buying or selling activity has historically been observed. These are not predictive guarantees.
- Volume: The number of shares traded. Some analysts study volume patterns alongside price movements.
3. Index Concentration
One characteristic of the Nasdaq-100 that analysts frequently discuss is its concentration. A relatively small number of large companies can represent a significant portion of the index's total value. This means the index's performance can be heavily influenced by the results of just a few companies.
Investors researching index funds or ETFs that track the Nasdaq-100 may want to review the fund's prospectus to understand exactly how the index is replicated and what risks are involved.
4. Macroeconomic Factors
Like all equity indices, the Nasdaq-100 can be influenced by broader economic factors including:
- Interest rate changes by the Federal Reserve
- Inflation data (CPI, PCE)
- Corporate earnings reports
- Economic growth indicators (GDP)
- Global trade and geopolitical events
Understanding these relationships requires ongoing research and study. Economic conditions change, and past relationships between variables may not persist in the future.
