Investing in Internet of Things Stocks

Updated: April 27, 2020, 3:14 p.m.

Computers and smartphones aren’t the only devices connecting to the internet. Everyday objects such as light bulbs, TVs, major appliances, and even doorbells are increasingly featuring internet connectivity. The Internet of Things (IoT) comprises all of these devices and objects, all communicating with each other and with data centers over the internet.

Investing in IoT is tricky because so many companies are involved in its various aspects, including businesses that make or provide:

  • Consumer devices such as fitness trackers, connected security cameras, and smart speakers.
  • Sensors, chips, and other hardware that serve the industrial and commercial markets.
  • Software platforms for managing IoT devices.
  • Cloud computing services for the processing power needed to churn through all the data IoT devices generate.

Pick any large technology company, and chances are, it’s involved in IoT in some way.

So many companies are focusing on IoT because IoT is a growth business. IDC estimates that total spending on consumer and industrial IoT technology and services will surpass $1 trillion by 2022, growing at a double-digit rate. That’s a massive pie, and it’s expanding quickly.

There are many ways to invest in IoT. Here are five options, ranging from a tried-and-true tech giant to smaller pure-play companies.

The Internet of Things goes far beyond consumer devices. Dexcom (NASDAQ:DXCM) is focused on diabetes management, specifically on medical devices used for continuous glucose monitoring. The company’s G6 system includes an auto-applicator, a sensor and transmitter, and a touchscreen receiver displaying real-time glucose data. Compatible smartphones and smartwatches can also be used to display data.

The number of people in the U.S. with diagnosed diabetes grew from 1.58 million in 1958 to 23.35 million in 2015, according to data from the Centers for Disease Control. Dexcom estimates that market penetration for continuous glucose monitoring for people on intensive insulin therapy is 35% to 40% for type 1 diabetes and just 15% for type 2 diabetes.

The combination of growing rates of diabetes and the transition to continuous glucose monitoring gives Dexcom plenty of growth opportunities in the coming years. In 2019, Dexcom’s revenue grew 43% to $1.48 billion.

Dexcom is an expensive stock relative to its revenue, valued at more than $25 billion. But for those willing to take on some risk to gain exposure to both IoT and healthcare, it’s a stock to consider.

Impinj (NASDAQ:PI) is the smallest stock on this list, valued right around $500 million. The company specializes in solutions involving radio-frequency identification, or RFID. Impinj’s RFID tags are used by retailers, manufacturers, and logistics companies to track inventory and assets.

The market for RFID products, including tags, readers, software, and services was worth $11 billion in 2018, according to IDTechEx, and it’s expected to grow to $13.4 billion by 2022. Apparel retail is so far one of the biggest markets by volume for RFID technology, with around 8 billion RFID labels used in 2018 to tag apparel items.

Impinj estimates that just 0.1% of connectable items are connected today. In the long run, trillions of consumable objects, ranging from food packaging to tires, could be tracked using RFID technology. Each RFID endpoint cost just pennies, making the technology economical for a wide array of use cases.

Impinj is a small company, with just $152.8 of revenue in 2019. It has shipped over 30 billion RFID endpoints over its lifetime, and that number could rise substantially in the coming years. Impinj is far from a sure thing as an investment, but it’s a company to watch in the IoT space.

5. Global X Internet of Things ETF

If picking individual stocks isn’t your thing, you can still gain exposure to IoT by investing in the Global X Internet of Things (NASDAQ:SNSR) exchange traded fund. This ETF holds positions in dozens of IoT-related companies; Dexcom represents its largest holding. Others include semiconductor companies that make chips for IoT devices, companies that make the devices themselves, and tech giants such as Cisco and IBM (NYSE:IBM).
