How large are market fluctuations?

Market fluctuations are an integral part of the investment landscape, representing the rise and fall of asset prices over time. As a financial analyst, it is essential to delve into the nature and extent of these fluctuations to help investors navigate the volatile terrain. In this article, we will explore the size of market fluctuations and how different investment instruments experience varying levels of volatility. By understanding these dynamics, investors can make informed decisions and avoid common pitfalls that hinder long-term wealth creation.

Volatility as a Measure of Fluctuations

To gauge the extent of market fluctuations, we rely on a statistical measure known as volatility. Volatility quantifies the degree of price variability observed in a particular investment or market. Higher volatility implies larger price swings and greater uncertainty, while lower volatility suggests more stable price movements.

Different Investments, Different Volatility Levels

Market fluctuations vary significantly across different investment categories. Let's examine the volatility levels associated with various investment instruments to gain a comprehensive understanding:

  1. Fixed Instruments: Fixed instruments, such as government bonds, are known for their stability and relatively low volatility. These markets tend to experience minimal fluctuations in comparison to other investment options.

  2. Commodities: The price of commodities is susceptible to significant market fluctuations. Factors such as supply and demand dynamics, geopolitical events, and economic conditions can cause commodity prices to swing dramatically. As a result, commodity markets often exhibit higher volatility compared to fixed instruments.

  3. Small-Cap Stocks: Small-cap stocks, which represent companies with relatively small market capitalization, can experience pronounced fluctuations. The smaller size and potentially limited liquidity of these stocks make them more susceptible to market volatility. Investors in small-cap stocks should be prepared for higher levels of fluctuations.

  4. Emerging Markets: Emerging markets exhibit higher volatility compared to established markets. These markets are characterized by factors such as political instability, regulatory changes, and economic uncertainties, which contribute to amplified price swings. Investors seeking exposure to emerging markets must consider the associated risk of significant market fluctuations.

Magnitude of Market Fluctuations

When analyzing market fluctuations, it is crucial to assess the magnitude of price swings. While fluctuations can occur in any investment, the range of price movements can vary substantially. Let's examine the potential scale of market fluctuations using historical examples:

  1. Microsoft's IPO: The launch of Microsoft's initial public offering (IPO) in 1986 serves as an illustrative case. Although Microsoft's stock has witnessed tremendous growth over the years, the journey was not without significant price fluctuations. Investors who had the discipline to hold onto their shares throughout experienced substantial gains. For example, a modest $1,000 investment in Microsoft's IPO would have grown to approximately $30 million today. However, very few investors possessed the fortitude and faith in the company to endure the price fluctuations and benefit from this remarkable growth.

  2. Everyday Investors' Performance: Numerous studies have shown that everyday investors tend to underperform the market average. This underperformance is attributed, in part, to investors' tendencies to sell their positions during market downturns and hesitate to re-enter the market when it shows upward momentum. Such behavior results in missed opportunities for gains and often leads to suboptimal investment outcomes.


Fluctuations are represented in terms of volatility, and different types of investments experience different levels of volatility.

The answer here depends on which market you’re talking about. Generally speaking, the capital markets in fixed instruments, such as government bonds, are the least volatile. Market fluctuations of the price of commodities, small-cap stocks, and emerging markets are the largest, and can be as high as 30-40% per year.

You’d better be able to stomach the fluctuations of volatile investments; otherwise, you’re almost always doomed to lose the money. For example, among those who originally bought the shares of Microsoft when it went public, less than one thousandth of one percent still have it.

A modest $1,000 invested in Microsoft’s IPO in 1986 would have become approximately $30 million today. But how many people had the self-discipline and faith in the company to hold their shares through all the price fluctuations over the years?

Very, very few – which is a revealing statistic not just about everyday investors who may not have the stomach to endure so many fluctuations, but also about the more sophisticated investors among us, who were savvy enough to scoop up the IPO when it became available.

Studies suggest that everyday investors have underperformed the market by almost 6% on average in many time periods, and a huge reason for this is that they are likely to ditch their positions at low points and are slow to get back on board when momentum is moving upwards again.
