Sector rotation involves moving money between different parts of the stock market as economic conditions change. Investors aim to invest in sectors that may perform better at different economic stages. You can use this strategy by investing in ETFs, which can offer a simple way to invest in specific sectors. Keep reading to learn about common approaches, including economic-cycle, calendar, and geographic sector rotation, as well as their risks and you can use ETFs effectively.
Reasons Investors Opt for Sector Rotation
As the economy moves forward, different sectors of the economy tend to perform better than others. The performance of these sectors can be a factor of the stage of the business cycle, the calendar, or their geographic location.
Investors seeking to beat the market may spend countless hours reading through articles and research reports. Using a top-down approach, they might develop a basic forecast of the economy, followed by an assessment of which industries hold the most promise. Then the real work begins–trying to find the right companies to buy.
A simpler alternative is to use ETFs that focus on specific sectors. Sector rotation takes advantage of economic cycles by investing in the sectors that are rising and avoiding the ones that are falling.
Sector rotation is a blend of active management and long-term investing: active in that investors need to do some homework to select the sectors they expect to perform well; long-term in that they can hold some sectors for years.
Markets tend to anticipate the sectors that will perform best, often three to six months before the business cycle starts up. This requires more homework than just buying and holding stocks or mutual funds, but less than trading individual stocks. The key is to always buy into a sector that is about to come into favor while selling the sector that has reached its peak.
Investors might consider three sector rotation strategies for their portfolios. The most well-known strategy follows the normal economic cycle. The second strategy follows the calendar, while the third focuses on geographic issues.
Understanding the Economic-Cycle Strategy
Sam Stovall of Standard & Poor’s describes a sector rotation strategy that assumes the economy follows a well-defined economic cycle, such as the one defined by the National Bureau of Economic Research (NBER). His theory asserts that different industry sectors perform better at various stages of the economic cycle in a predictable way.
The 11 sectors of the S&P 500 are aligned with each stage of the business cycle. Each sector follows its cycle as dictated by the stage of the economy. Investors should buy into the next sector poised to move higher. When a sector reaches the peak of its move as defined by the economic cycle, investors should sell that ETF sector. Using this strategy, an investor may invest in several sectors at the same time as they rotate from one to another, all guided by the stage of the economic cycle.
The major problem with this strategy is that the economy usually does not follow the economic cycle exactly as defined. Even economists cannot always agree on the trend of the economy. It is important to note that misjudging the stage of the business cycle might lead to losses, rather than gains.
Warning
In order to be profitable, a successful sector rotation strategy must not only beat the market, but also beat it by a large enough margin to exceed any commissions and transaction costs.
Exploring the Calendar Strategy
The calendar strategy takes advantage of those sectors that tend to do well during specific times of the year. The midsummer period before students go back to school often creates additional sales opportunities for retailers. Also, the Christmas holiday often provides retailers with additional sales and travel-related opportunities. ETFs that focus on the retailers who benefit from these events stand to do well during these periods.
There are many examples of cycle-specific consumer events, but an easy one to classify is the summer driving season. People in the Northern Hemisphere tend to drive more during the summer months. This increases the demand for gasoline and diesel, creating opportunities for oil refiners. Any ETF that has a significant portion of its holdings in companies that refine oil may benefit. However, as the season winds down, so will the profits of that related sector’s ETFs.
Introduction to Geographic Strategy
The third sector rotation perspective investors can employ is to select ETFs that capitalize on potential gains across one or more global economies. Maybe a country or region is benefiting from demand for the products it produces. Or perhaps a country’s economy is growing faster than the rest of the world’s. There are ETFs that offer investors an opportunity to play such trends without having to buy individual stocks.
Important
The effectiveness of sector rotation has been disputed. Investors must be able to correctly anticipate the start of a market downturn and then anticipate when the downturn ends. They must also correctly identify the sectors that will perform well during and after the downturn. A 2023 study found “modest outperformance, which quickly diminishes after allowing for transaction costs and incorrectly timing the business cycle.”
Risk Management in Sector Rotation
Like any investment, it is important to understand the risks of the sector rotation strategy and the corresponding ETFs before committing capital. By investing in several sectors at the same time, weighted by your expectations of future performance, you can create a more diversified portfolio that helps reduce the risk of being wrong about any particular investment.
An ETF strategy naturally spreads stock selection risk across all companies in the ETF. However, investors should be careful they do not create unwanted concentration in any one sector, especially when using a blend of the economic-cycle, calendar, and geographic strategies.
With so many ETFs available to investors, it is important to understand the ETF’s investment strategy and portfolio composition before committing capital. Moreover, lightly traded ETFs pose additional risk in that they may be difficult to sell quickly if there is no underlying bid for the shares.
The Bottom Line
By investing in a diversified set of ETFs, an investor using sector rotation strategies is positioned to take advantage of an uptrend in certain sectors while reducing the risk of losses from exposure to high-risk stocks. In addition, by selling a portion of your holdings in sectors that are at the peak of their cycle and reinvesting in those sectors that are expected to perform well in the next few months, you are following a disciplined investment strategy.
A sector rotation strategy using ETFs provides investors with an optimal way to enhance portfolio performance and increase diversification. Just be sure to assess the risks in each ETF and strategy before committing your money.
