The NASDAQ 100 Index
The NASDAQ 100 contains the 100 largest non-financial companies listed on the NASDAQ exchange. Unlike the broadly diversified S&P 500, the NASDAQ 100 is heavily technology-focused — the top 7 companies (Apple, Microsoft, Nvidia, Amazon, Meta, Alphabet, Tesla) together account for over 50% of the index.
This concentration makes the NASDAQ 100 the most volatile of the major US indices. For daytraders, this means: larger moves, more opportunities — but also higher risk.
Why the NASDAQ is More Volatile
Mega-Cap Concentration
When Apple drops 3%, it moves the NASDAQ by roughly 0.5% — from a single stock alone. In the S&P 500, the impact would be only half as large. This concentration means individual earnings reports can move the entire index by 2-3% in a single day.
Interest Rate Sensitivity
Tech stocks are particularly rate-sensitive. Many tech companies are valued on their future earnings potential (growth stocks). When rates rise, the present value of future earnings falls — and so does the stock price. Every Fed comment on rates hits the NASDAQ harder than other indices.
Innovation and Disruption
The tech sector is characterized by rapid change. A new AI model, a chip shortage, or a regulatory decision (e.g., antitrust action against Big Tech) can move the NASDAQ by hundreds of points within hours.

Trading Hours and Sessions
Pre-Market (4:00-9:30 AM EST)
NASDAQ futures react strongly to pre-market earnings releases. When a mega-cap like Nvidia or Apple reports after hours, futures move overnight — and the next day's open can show a significant gap.
US Session (9:30 AM-4:00 PM EST)
Highest liquidity, tightest spreads. The first 30 minutes (9:30-10:00) and the last hour (3:00-4:00) are the most volatile. Many institutional traders and algorithms are particularly active in these windows.
Best Practice for European Traders
Focus on 3:30-7:00 PM CET. This window overlaps European and US sessions, and the most important US economic data has already been released.
NASDAQ Sentiment on Sentmo
What is Typical
The NASDAQ often has a stronger long bias among retail traders than other indices. Values of 55-65% long are "normal" for the NASDAQ. Only above 70-75% does the contrarian signal become relevant.
Earnings Season as Sentiment Catalyst
During earnings season (especially when Apple, Microsoft, Nvidia, Amazon, Meta, or Alphabet report), sentiment data can shift dramatically within 24 hours. The 24h change on Sentmo is particularly informative during these weeks.
Correlation with Tech Sentiment
When both NASDAQ AND SPX500 simultaneously show extreme retail long positioning (>75%), it is a stronger signal than when only one index is extreme. You can spot these cross-index patterns on the Sentmo dashboard at a glance.

Risk Management for the NASDAQ
The NASDAQ can move 3-5% on extreme days (earnings, Fed, geopolitical events) — that is 500-800 points. Your risk management must reflect this:
Conclusion
The NASDAQ 100 is the instrument for traders who do not fear volatility but want to harness it. The strong concentration on tech mega-caps makes it simultaneously more predictable (because few stocks dominate the index) and riskier (because single events have large impacts). Sentiment data from Sentmo helps you read the crowd's mood — and trade against it when the extremes justify it.
