Demystifying Stock Market Indices and Visualizing Historical Market Probabilities
Weekly updates on the innovation economy.
Introduction
Understanding market structure, historical outcomes, and a changing investing landscape can help more investors get the odds of investing success in their favor.
In this week’s newsletter, Drawing Capital utilizes a data-informed approach to assess and analyze equity index data across the past few decades for the NASDAQ 100 Index (index ticker: NDX), S&P 500 Index (index ticker: SPX), Dow Jones Industrial Average (index ticker: INDU), and the Russell 2000 Index (index ticker: RTY).
Obviously, while future performance can deviate from historical returns, understanding the historical return profile and distribution of event probabilities helps to imagine investing possibilities and provide a historical context.
Additionally and in March 2021, Drawing Capital partnered with Interactive Brokers to present a webinar on this data, and a recording of the webinar can be found here:
A quick note: when this article refers to “buying the index”, this is a theoretical proposition. In reality, it is typically not possible to actually “buy the index”, and investors seek to track the performance of an index through buying a high-quality index fund. Traits that help determine if an index fund is of high quality include:
Low tracking error relative to an underlying benchmark index
Low expense ratios and fees
High liquidity and volume
High reputation and quality of index fund provider
Calendar Year Returns for Popular US Equity Indices
For the first 5 months of 2021, the IWM ETF, which is a measure of US small-cap companies, has outperformed the 3 other ETFs in this chart.
Key Insights:
The clustering of returns from 1995-1999, followed by 2000-2002, demonstrates the significance of the bubble in telecom, technology, and internet stocks, followed by the bursting of the dot-com bubble.
Aside from a near 1% loss in 2018, the NASDAQ 100 Index has generated strong returns since 2009.
Despite the coronavirus crisis and resulting economic catastrophe, the NASDAQ 100 Index enjoyed strong positive performance in 2020, highlighting the strong demand in innovation-focused themes, such as e-commerce, work-from-home beneficiaries, software companies that focus on digital transformation, fintech, biotech, and more.
Key Insights:
From 1988-2020, S&P 500 Index performance was positive for the majority of calendar years.
From 1988-2020, the 2008 calendar year was the worst calendar year performance for the S&P 500 Index.
Key Insights:
It is common to see positive double-digit percentage returns in a calendar year for the Russell 2000.
In 2008, the Russell 2000 experienced a smaller calendar year loss compared to the NASDAQ 100 and S&P 500.
Overall, it is clear that small companies and tech-focused companies provide some of the best growth stories, which helps drive the historical positive performance of the NASDAQ 100 and Russell 2000 indices.
Interestingly, despite the perception that small-cap companies are riskier than large-cap companies, this chart showcases that between 1988-2020, the Russell 2000 Index actually experienced a higher high-point and a better low-point compared to the S&P 500 Index in terms of calendar year returns.
Compared to the three other indices, the NASDAQ 100 Index historically has fewer calendar years of negative performance, and many of the negative performing years for the NASDAQ 100 Index were clustered around the bursting of the tech bubble in the years 2000-2002.
Assessing Probabilities and Historical Occurrences of Positive Performance Events
The “historical occurrences and return outcomes” in the following charts below demonstrate that longer holding periods are typically associated with better investment returns for these indices.
The phrase, “blindly buying”, refers to an investor randomly “buying” an index on any trading day at its closing price. In addition, by incorporating the “blindly buying” component to the analysis, it somewhat removes the timing element of buying and selling index funds, which supports a known phrase in the investment community: “time in the market is more important than timing the market”.
Key takeaway: Buying the NASDAQ 100 Index at the closing price of any trading day between 1988-2019 and holding this investment for 1 year would have produced a positive return about 84% of the time.
Key takeaway: Buying the NASDAQ 100 Index at the closing price of any trading day between 1988-2011 and holding this investment for 10 years would have at least doubled the investment’s value about 79% of the time.
Concluding Thoughts
Many very successful long-term investors care deeply about 2 traits: avoidance of permanent long-term capital loss (i.e. avoid losing money) and finding businesses that compound at high and growing rates of return.
While short-term investors are typically price-sensitive (and therefore are often focused on price multiples and current sentiment), long-term investors desire growing cash flows from a business over time, which thereby increases a company’s intrinsic value and stock price.
By evaluating the historical data for the NASDAQ 100 Index (index ticker: NDX), S&P 500 Index (index ticker: SPX), Dow Jones Industrial Average (index ticker: INDU), and the Russell 2000 Index (index ticker: RTY), it is clear that a longer holding period for index funds tracking these indices on average reduces the probability of permanent capital loss and simultaneously provides the opportunity to grow an investment’s value over time.
Notably, understanding market structure, historical outcomes, and a changing investing landscape can help more investors get the odds of investing success in their favor.
