PTON stock is my top pick among fitness stocks. For the current year, the stock has already surged 290%. I would wait for some correction before fresh exposure to the stock. As an overview, Peloton Interactive is in the business of fitness products that include the Peloton Bike and the Peloton Tread. These products feature touchscreens that stream on-demand classes. The company is on a high-growth trajectory, and this explains the stock surge. For the first quarter of 2021, the company reported revenue growth of 232% year-over-year. As a matter of fact, the company’s annual revenue growth has been more than 100% for the last six years. Further, for Q1 2021, the company reported positive adjusted EBITDA of $118.9 million. For the prior year, adjusted EBITDA was negative at $21 million. As the company’s EBITDA and cash flow increases, the stock will continue to trend higher. The company’s operating cash flow (OCF) for the first quarter was $312 million. This implies an annualized OCF of $1.2 billion. With the pandemic triggering demand for at-home fitness equipment, the company’s core business will be a cash-flow machine. Given the growth and future outlook of the company, PTON is a high-growth portfolio stock. If the stock does fall below $100 on profit booking, it would be a good time for fresh exposure.
