Most volatile Nasdaq Stock Market-listed stocks: Chinese and SaaS shares lead the volatility index
The Nasdaq Stock Market – home to many of the world’s major technology firms – often mirrors shifts in overall market risk appetite. During periods of changing monetary policy, advances in AI development and evolving corporate earnings expectations, price movements across its key constituents tend to become more pronounced.
The tech-heavy US Tech 100 Index has remained a focal point for market volatility in 2025, reflecting a divergence in performance across technology, consumer and AI-related sectors.
As of 24 November 2025, the NASDAQ Composite Index stood at 22,273.08, having reached a record high of 23,958.47 in October – indicating that heightened market fluctuations remain evident (Trading Economics).
What is the US Tech 100 Index?
The US Tech 100 tracks 100 of the largest non-financial companies listed on the Nasdaq Stock Market. The index is market-cap weighted, meaning larger firms exert a greater influence on its movements.
As of November 2025, the index comprises 102 constituents, reflecting ongoing shifts in sector composition and market leadership. Technology continues to represent over 50% of total weighting, while consumer discretionary and healthcare sectors together account for roughly 26%.
Apple (AAPL) remains the largest component, with an estimated 14% weighting, followed by Microsoft (MSFT) at 10%, Amazon (AMZN) at 6%, and Tesla (TSLA) at 4%, based on recent data.
For traders monitoring volatility, the US Tech 100 Volatility Index (VOLQ) and Volatility Index (VIX) provide insight into short-term market risk expectations, derived from option prices on Nasdaq Stock Market and S&P-based derivatives. Both indices have risen sharply since early November, with the VIX climbing over 50% to 25.3.

Understanding volatility in the Nasdaq Stock Market
Volatility measures how much a stock’s price fluctuates over a set period. Periods of broader market turbulence often lead to larger price swings, particularly in growth-sensitive sectors such as technology and software-as-a-service (SaaS).
A straightforward way to gauge volatility is through 52-week highs and lows – the wider the range, the greater the volatility. In 2025, AI valuations, uncertain monetary policy and geopolitical tensions have contributed to significant fluctuations across tech and China-linked names.

FAQ
How many stocks make up the US Tech 100 index?
The US Tech 100 index currently includes 102 constituent stocks, slightly above its traditional count of 100 due to periodic eligibility and weighting adjustments. The index tracks the largest non-financial companies listed on the Nasdaq Stock Market, with a strong emphasis on technology and innovation-driven sectors. As of November 2025, technology firms account for over half of the index’s total weighting, with the remainder spread across consumer discretionary and healthcare sectors.
How can I find volatile stocks?
Volatile stocks are often identified by analysing their 52-week price ranges or through volatility indices such as the Volatility Index (VIX). A wider gap between a stock’s high and low prices over a given period usually signals greater price fluctuation. Traders also monitor earnings announcements, macroeconomic data, and sector-specific developments, all of which can contribute to sudden market movements. Data providers such as Nasdaq Stock Market and Trading Economics regularly publish volatility metrics and charts that can assist in identifying these trends.
Should I invest in Nasdaq Stock Market-listed stocks?
Whether to invest in Nasdaq Stock Market-listed companies depends on individual financial goals, experience and risk tolerance. Nasdaq Stock Market-listed stocks, particularly those in technology and SaaS sectors, tend to experience faster price changes in response to economic conditions, interest rate shifts and company results. While volatility may create potential opportunities, it also increases the risk of loss. It’s essential to review market data, assess company fundamentals and understand all risks before making any trading or investment decisions. Past performance is not a reliable indicator of future results, and this information should not be regarded as investment advice.
