What Is an Airline Industry ETF?
An airline industry ETF is a sector exchange traded fund (ETF) that invests in the stocks of airline companies, so as to obtain investment results that correspond to those of an underlying airline index.
In reality, because of the very limited number of airlines in most nations, most ETFs associated with airline stocks also include other means of transportation, such as rail and marine.
- An airline industry ETF is an exchange traded fund that invests in the stocks of airline companies based on a particular airline index.
- An investor is able to gain a broad investment portfolio of airline stocks through an airline ETF rather than having to purchase single airline stocks.
- Two important metrics to pay attention to when investing in airlines are available seat miles (ASM) and revenue per available seat mile (RASM).
- Index-based ETFs are beneficial to investors in that they are low-cost and provide diversification within the sector.
- There is only one ETF that focuses purely on airlines. Other ETFs that include airline stocks also include marine and rail stocks, known as transportation ETFs.
Understanding an Airline Industry ETF
Airline industry ETFs are a way to invest broadly within the airline industry, but they aren’t all created equal.
Investors who are considering investing in airline companies, or any sector, should become familiar with the metrics that can help them determine the profitability and efficiency of companies within that sector. For airline companies, two key metrics are available seat miles (ASM) and revenue per available seat mile (RASM).
ASM is a measurement of a flight's ability to produce revenue; it measures the number of seat miles that can be sold on a particular aircraft: its carrying capacity. Seat miles are calculated by multiplying the miles an airplane will fly on a specific trip by the number of seats available for sale on that trip.
ASM is a crucial metric for investors as it allows them to identify airlines that are able to produce the most revenue. When some seats remain empty on a flight, the airline's ASM is below capacity. Over time, a pattern of empty seats on a particular airline proves very costly to the company.
A larger RASM tends to indicate higher profitability for the airline. Notably, the revenue is not only limited to ticket sales; it includes other influences such as profitability and efficiency.
Types of Airline Industry ETFs
When people think of airlines, they most always think of passenger airlines. However, airline stocks can include those of companies in the airline business but not specifically an airline company.
These can include stocks that provide services to airlines, such as catering companies, logistical planning companies for airlines, and even airlines that aren't necessarily passenger airlines, such as freight airlines.
In reality, there is only one ETF that focuses solely on airline industries, which is the U.S. Global Jets ETF. Other ETFs that incorporate airlines in their investment portfolio are transportation ETFs, which, in addition to holding airline stocks, hold rail stocks and marine stocks.
Advantages and Disadvantages of an Airline Industry ETF
The airline industry is susceptible to a number of factors that can affect demand for air travel; these include economic downturns, terrorism, and inclement weather. An airline ETF may underperform at such times, as well as when fuel prices are surging, since the cost of aviation fuel has a major impact on airline profitability.
The performance of airlines is heavily dependent on the behavior of consumers as the primary use of airlines is for passenger travel when people take vacations. Taking a vacation is a luxury and not a necessity, so when the economic atmosphere shifts from one of spending to one of saving, airline stocks will suffer.
There are compelling reasons why an airline industry ETF could make sense for investors looking to capitalize on growth trends in transportation.
Firstly, ETFs are passive investments that don't require the fund manager to take significant investment action or come up with alpha strategies. An ETF simply tracks an index by picking stocks in that index. As such, ETFs have low turnover and low expense ratios, making them an affordable investment option.
People will always travel, whether that be for personal reasons or business, and mail and cargo will also always need to be delivered internationally. Airlines aren't going anywhere and as developing economies continue to increase their wealth, even more people will be traveling who couldn't afford to before.
The International Air Transport Association (IATA) expects around 7.8 billion passengers to travel by air in 2036, nearly twice the amount of people who traveled by air in 2017.
