Investing in Different Sectors via ETFs

justETF.com

Sector ETFs add another string to the private investor's bow, enabling additional options for portfolio diversification and strategy.

Investing in Different Sectors via ETFs Investors and economists have long grouped companies according to the industry sector the firms are most exposed to.
 
The reason is obvious. Companies operating in similar areas of the economy will typically face similar opportunities and challenges, and are also likely to be impacted as a group by developments in the economic cycle.
 
A car manufacturer might produce superior vehicles or be more efficiently run than a rival, for instance. But external factors such as new government regulations, a rise in raw material costs or a recession will hit all carmakers to some degree.
 
 

Why invest in sector ETFs

Sector ETFs make such observations investable. They enable you to gain instant exposure to a basket of stocks in an industry sector via the purchase of a single ETF.
 
For instance the db x-trackers MSCI World Health Care Index ETF tracks the health care sector of developed markets worldwide. Top holdings include Johnson & Johnson, Novartis, Pfizer, and Roche.
 
To gain exposure to this sector before the advent of sector ETFs, you would have had to purchase these stocks individually (which would be costlier to implement and riskier because you're picking individual stocks) or else put money into an actively managed healthcare fund (where you will pay higher annual fees and risk underperformance due to poor fund manager decisions).
 
In contrast today, with sector ETFs, anyone can trade in and out of different sectors cheaply and easily. This means it's now practical for ETF investors to pursue alternative methods of portfolio construction when it comes to your equity holdings, such as diversifying across sectors rather than by geographic allocation.
 
You can also employ a sector rotation strategy. Here you seek to overweight the sectors most likely to benefit from the next stage of the economic cycle. Alternatively, you might not trade your positions but instead permanently overweight particular sectors that you think have the best long-term prospects. For instance if you think energy production will benefit as the growing global population increases its consumption, you might hold a large position in an energy sector ETF.

What do sector ETFs invest in?

Sector ETFs are index-tracking funds. They track sector indices maintained by the index providers. These indices are based on one of two different internationally recognised sector classification schemes:
 
  • The Industry Classification Benchmark (ICB)
  • The Global Industry Classification Scheme (GICS)
In practical terms the classifications are very similar. STOXX Limited uses the ICB system for its indices, while MSCI employs GICS. Families of sector ETFs focus on the broadest categories, and sector ETFs are available to track regional as well as global sector indices. An overview is provided in the table below.

In addition, thematic ETFs have emerged in recent years, which are sector plays tracking more specialist indices.
 
For example, with the ETFS ROBO-STOX Global Robotics and Automation ETF you can get exposure to the high-tech manufacturing devices of the future, as represented by firms in the ROBO-STOX Global Robotics and Automation Index. These are more niche investments, and investing in them is closer to a stock picking approach than a broader sector allocation or rotation strategy.

 

Some potential downsides of sector ETFs

It's always important to consider costs when investing, and sector ETF fees are typically higher than those of regional or country-based ETFs. This makes it more expensive to hold a portfolio constructed using a sector-based approach. Be especially vigilant with more exotic or niche sector ETFs that may have a relatively small amount of Assets under Management, and hence higher costs.
 
Also note that with a sector rotation strategy, you're not buying the whole market, but rather taking an active approach and holding a sub-set of companies in order to try to outperform. If you decide to follow a sector rotation strategy, you'll therefore have to get your sector calls more right than wrong if you're going to beat the (cheaper) market cap weighted indices. Make the wrong decisions and you'll underperform instead.

Hint for searching ETFs
Filter for "All Sectors" in order to get all ETFs which focus on sectors. If you want to exclude all sector ETFs from your search, choose the "No Sectors" filter.
