1. Roku

Roku is benefiting from the long-run secular trend where consumers are switching from linear TV to streaming viewership. The rate of the shift may fluctuate but it's unlikely to change direction. According to Roku management, eventually, content will be 100% streaming. Indeed, here is what founder and CEO Anthony Wood said in its most recent conference call:

But I think the big picture for me is that we're still in the middle of this transition where viewers, advertisers, and the industry is moving 100% to streaming. We're just not there yet, but it's moving and it's happening. If you look, one stat I think that's interesting from Nielsen is that if you look at 18 to 45-year-olds, 39% of their TV watching is streaming.

Roku has accumulated 55.1 million accounts, a 28% increase from the second quarter of last year. Undoubtedly, the pandemic helped accelerate customer acquisition. Folks were limited in entertainment options when ballparks, concerts, restaurants, and movie theaters were all shut down for most of the previous year. 

The company's operating system is reliable and fast. That's led many original equipment manufacturers to build TVs with Roku's operating system natively installed. Roku is the No. 1 TV operating system in the U.S. and Canada, and it's well on its way to international expansion.

2. Chewy 

Chewy is an exclusively online pet retailer. The company boasts 19.8 million active customers, 31.8% more than it had last year. The pandemic caused millions of pet parents to look for new options to fulfill their pet's everyday needs. Some may never return to shopping in brick-and-mortar stores. One reason is that Chewy offers customers automatic delivery of their pet's food and medicine.

Indeed, in its most recent quarter, 69.3% of overall sales were through automatic delivery, or what Chewy calls Autoship. It makes people's lives easier as it is one less thing they need to remember. Chewy even offers a small discount on orders placed through Autoship. The company is piggybacking off the long-run spending moving online from retail locations.

Revenue is growing rapidly, and Chewy is doing it efficiently. Its gross profit margin expanded from 16.6% in 2016 to 25.5% in 2021.   

Investor takeaway 

Roku and Chewy are doing an excellent job capturing their respective markets and solving a problem for their customers. Streaming content costs less, and viewers get liberated from lengthy cable contracts. Chewy gives pet parents the peace of mind to know food and medicine can be delivered automatically. 

The one hesitation investors could have with these two companies is their relatively rich valuations. Putting these stocks on your watch list and waiting for a market correction to buy could minimize that hesitation.
