What happened Shares of stationary bike- and treadmill-seller Peloton Interactive (NASDAQ: PTON) suffered a near-5% sell-off this morning. It's recovered somewhat in the afternoon, but is still down 3% as of 12:35 p.m. EDT. And you can probably blame UBS for that. Image source: Getty Images. So what In a report out this morning, Swiss megabanker UBS doubled down on its sell rating on Peloton stock. Peloton, explains UBS in a report covered by TheFly.com today, is the victim of inflated expectations among the analysts who follow it. You see, currently, Peloton has penetrated about 3% of the market for connected fitness subscriptions (which UBS defines as households earning at least $75,000 a year, and exercising at least twice per week). That's twice where Peloton was at at this time in 2020, and more than four times its penetration in 2019 -- but Wall Street is counting on Peloton to more than triple its current penetration again by 2025, and to grow its revenue 42% annually over the next four years. UBS warns that this is unlikely to happen. Guesstimating that Peloton might hit 7.7% penetration by 2024 perhaps, and then trend toward slower growth, the analyst foresees 38% annualized revenue growth through that year -- somewhat short of Street estimates, and justifying a sell rating and a $74 price target on the stock. Now what Granted, even if UBS is right, 38% annualized sales growth would be really impressive. But the question investors need to keep in mind is whether 38% sales growth (or even 42% for that matter) is fast enough to justify paying nearly 160 times earnings for Peloton stock today. UBS thinks it might not be, and I'm inclined to agree. 10 stocks we like better than Peloton InteractiveWhen our award-winning analyst team has a stock tip, it can pay to listen.
