Nasdaq 100 Explained: All You Need to Know

Nasdaq 100 Explained: All You Need to Know

The Nasdaq 100 is one of the most closely watched stock indexes in the world. It tracks 100 of the largest non-financial companies listed on the Nasdaq exchange, representing sectors like technology, consumer services, healthcare, and communication.

Unlike broader benchmarks such as the S&P 500, the Nasdaq 100 excludes banks and insurance firms. That makes it heavily tilted toward growth and innovation, where tech giants like Apple, Microsoft, Amazon, Nvidia, and Alphabet dominate the weightings.

In 2025, the index remains the heartbeat of the global growth trade. A mirror of market confidence in AI, semiconductors, and digital transformation.

A Short History

The Nasdaq launched the Nasdaq-100 on January 31, 1985 to spotlight the largest non-financial companies on its market. Over four decades the index evolved into a global large-cap growth benchmark with a sizeable product ecosystem built around it.

Why the Nasdaq 100 Matters

The Nasdaq 100 is often viewed as a barometer for global risk sentiment. When it rallies, investors tend to embrace risk. When it sells off, caution returns.

Here’s why it matters:

• Its tech-heavy composition captures the world’s leading innovators.
• Its earnings reports often set the tone for broader markets.
• Its valuation sensitivity to interest rates makes it a key gauge for Fed policy expectations.

As of October 2025, the Nasdaq 100 is up roughly 19.5% year-to-date, reflecting strong performance from semiconductor and AI-related companies. It reached a record closing high of 22,190.52 on June 24, 2025, underlining the resilience of growth leaders.

How the Nasdaq 100 Is Built

The index follows a modified market-capitalisation weighting method. That means larger companies carry more influence, but caps are placed to prevent any single stock from dominating.

Key facts:

• Eligibility: Must be Nasdaq-listed and non-financial.
• Rebalancing: Reviewed quarterly to reflect current market capitalisation.
• Weight cap: No company can exceed 14% of the index at a rebalance.

This structure ensures the Nasdaq 100 evolves with market leadership — adding rising stars and trimming laggards over time.

What Moves the Nasdaq 100

Several forces drive daily and long-term moves in the Nasdaq 100:

1. Corporate Earnings

Earnings from top constituents like Nvidia, Microsoft, and Amazon can swing the entire index. A strong earnings season typically lifts sentiment across global equities.

2. Interest Rates

Tech valuations depend heavily on discount rates. Falling yields generally boost growth stocks, while rising rates can pressure them.

3. Innovation Trends

Breakthroughs in AI, chips, cloud, and software often trigger sector-wide rallies. In 2025, the AI boom has been a dominant driver.

4. US Dollar and Global Demand

A stronger dollar can weigh on overseas earnings of multinational Nasdaq firms, while global tech spending boosts their outlook.

Nasdaq 100 vs Other Indexes

Before diving deeper into trading strategies, let’s compare how the Nasdaq 100 stacks up against other major U.S. benchmarks. Understanding these differences helps investors see where each index fits, from the tech-heavy Nasdaq 100 to the broader, more diversified S&P 500 and Nasdaq Composite.

Feature	Nasdaq 100	S&P 500	Nasdaq Composite
Coverage	100 large non-financial Nasdaq stocks	500 large U.S. stocks	3,000+ Nasdaq-listed companies
Sector Bias	Tech & Growth	Broad Economy	Broad but tech-heavy
Financials Included	No	Yes	Yes
Volatility	Higher	Moderate	Higher

The Nasdaq 100 delivers focused exposure to innovation leaders, while the S&P 500 offers a broader economic mix.

How to Trade or Invest in the Nasdaq 100

There are multiple ways to gain exposure depending on your capital size, strategy, and risk appetite.

1. ETFs (For Investors)

• Invesco QQQ (QQQ) – The most popular Nasdaq 100 ETF, known for deep liquidity and tight spreads. Expense ratio: 0.20%.
• Invesco QQQM (QQQM) – Same index, designed for longer holding with a 0.15% total expense ratio.

QQQ is prized for deep liquidity. QQQM offers the same exposure at a lower ongoing fee for buy-and-hold use.

2. Futures (For Active Traders)

• E-mini Nasdaq 100 (NQ) – $20 per index point; minimum tick 0.25 index point. Near 24-hour access.
• Micro E-mini Nasdaq 100 (MNQ) – $2 per index point; great for smaller accounts. Minimum tick 0.25 index point. Smaller notional for fine-tuned risk.

These contracts allow precise exposure and hedging against short-term volatility.

Rule of thumb: A 1-point move equals $20 on NQ and $2 on MNQ.

3. Options (For Defined-Risk Strategies)

NDX index options and XND micro index options are cash-settled and European-style. XND is 1/100th of NDX, helpful when you want smaller notional exposure. Options on QQQ are also widely used for ETF-based strategies because it lets you structure directional, hedging, or income trades.

• NDX options: Cash-settled, suitable for institutions.
• XND options: Mini versions designed for retail traders.

Common Trading Approaches

Strategy	Idea	Typical Tool
Trend Following	Ride sustained uptrends; use pullbacks to add	QQQ / Futures
Breakout Plays	Trade confirmed range breaks	Futures / Options
Pairs or Hedges	Long Nasdaq 100, short S&P 500 (growth vs value)	Futures
Earnings Season Positioning	Use options spreads to limit risk around key results	NDX / QQQ options

Each approach should include stop-loss discipline and clear position sizing.

Key Risks to Watch

1. Concentration Risk – Top 10 names account for over half of index weight.
2. Valuation Risk – Rich multiples can compress sharply if growth slows or yields rise.
3. Liquidity & Gap Risk – Volatile news cycles can cause sharp overnight swings in futures.

Balancing exposure with diversification and disciplined risk management remains essential.
