Market Volatility and Roller Coasters

Market Volatility can best be imagined as a roller coaster: up and down, sometime sideways, with precipitous drops and fast accelerations. A relatively recent ‘wild ride’ allows us an opportunity to examine our expectations and determine whether the fear is real or imagined, and how best to keep our perspective.

From February 1–5, the US market (as measured by the Russell 3000 Index) fell almost 6%, causing many investors to wonder what the future holds and if they should make changes to their portfolios.  The media hyperbole certainly contributes to that feeling of panic. While it may be difficult to remain calm during a substantial market decline, it is important to remember that volatility is a normal part of investing. Additionally, for long-term investors, reacting emotionally to volatile markets may be more detrimental to portfolio performance than the draw down itself.

Intra-year declines

Exhibit 1 shows calendar year returns for the US stock market since 1979, as well as the largest intra-year declines that occurred during a given year. During this period, the average intra-year decline was about 14%. About half of the years observed had declines of more than 10%, and around a third had declines of more than 15%. Despite substantial intra-year drops, calendar year returns were positive in 32 years out of the 37 examined. This goes to show just how common market declines are and how difficult it is to say whether a large intra-year decline will result in negative returns over the entire year.

Reacting impacts performance

If you tried to time the market in order to avoid the potential losses associated with periods of increased volatility, would this help or hinder long-term performance? If current market prices aggregate the information and expectations of market participants, stock mis-pricing cannot be systematically exploited through market timing. In other words, it is unlikely that investors can successfully time the market, and if they do manage it, it may be a result of luck rather than skill. Further complicating the prospect of market timing adding to portfolio performance, is the fact that a substantial proportion of the total return of stocks over long periods comes from just a handful of days. Since investors are unlikely to be able to identify in advance which days will have strong returns and which will not, the prudent course is likely to remain invested during periods of volatility rather than jump in and out of stocks. Otherwise, an investor runs the risk of being on the sidelines on days when returns happen to be strongly positive.

Exhibit 2 helps illustrate this point. It shows the annualized compound return of the S&P 500 Index going back to 1990 and illustrates the impact of missing out on just a few days of strong returns. The bars represent the hypothetical growth of $1,000 over the period and show what happened if you missed the best single day during the period, and what happened if you missed a handful of the best single days. The data shows that being on the sidelines for only a few of the best single days in the market would have resulted in substantially lower returns than the total period had to offer.

(Second chart) In US dollars. For illustrative purposes. The missed best day(s) examples assume that the hypothetical portfolio fully divested its holdings at the end of the day before the missed best day(s), held cash for the missed best day(s), and reinvested the entire portfolio in the S&P 500 at the end of the missed best day(s). Annualized returns for the missed best day(s) were calculated by substituting actual returns for the missed best day(s) with zero. S&P data © 2018 S&P Dow Jones Indices LLC, a division of S&P Global.

Conclusion

While market volatility can be nerve-racking for investors, especially those who are already retired, reacting emotionally and changing long-term investment strategies in response to short-term declines proves more harmful than helpful. By adhering to a well-thought-out investment plan – your allocation mix that determines the type of roller coaster you can live with over the long term – will help you remain calm during periods of short-term uncertainty. None of us can control the volatility of the market, but we can control how we respond to it by understanding what is ‘normal’ and keeping our emotions in check.
