Wall Street analysts said this week they're recommending investors buy stocks that have the potential for outsized growth. These companies are safe long-term bets and will reward investors handsomely, analysts said. CNBC Pro combed through the top Wall Street research to find the top long-term buying opportunities. They include: Wabtec , World Wrestling , Nio , XP and Warby Parker. Wabtec Wabtech is firing on all cylinders, according to Raymond James analyst Felix Boeschen. The firm said in its initiation of the stock that the "multi-year growth algo is accelerating." Shares of Wabtech, which makes technology products for locomotives, freight and transit vehicles, are up almost 4% over the last month. Boeschen said he sees signs of a recovery taking hold in key freight markets particularly in North America, which should supercharge growth. Wabtech is uniquely positioned to "capitalize on global decarbonization efforts across the transportation space," he added. Another key generator of revenue is locomotive modernization, according to Boeschen, who expects double-digit growth in that segment. Work-from-home remains a headwind as North American transit is still in a slum, but the analyst said he's not giving up on the stock. "All said, after running our detailed risk/reward analysis through, we see a largely favorable upside/downside skew for shares of WAB," Boeschen wrote. Nio The "overseas expansion [is] charging forward" for Nio, according to Deutsche Bank analyst Edison Yu. The firm said in a recent note that, while investors are squarely focused on sales in China, it's Nio's rapidly growing expansion plans that's aren't getting enough attention. The China electric vehicle company is very quietly making inroads into countries like Europe and eventually the United States, according to the firm. Yu called recent developments an "an underappreciated aspect of NIO's long term growth prospects." "We certainly don't expect meaningful volume contribution anytime soon as management is very focused on organic brand building but note in Norway YTD, NIO has sold nearly 600 ES8 SUVs, putting it slightly behind Mercedes Benz EQB and BMW IX3," Yu said. The company's CEO also recently visited its U.S. headquarters and it's an important moment in Nio's evolution, Deutsche said. "We think perhaps NIO's desire to enter the US may be far greater than it appears especially given how competitive the domestic Chinese market is becoming," Yu wrote. Shares are up 4.6% over the past month. Warby Parker Warby Parker shares are down 23% since the company's mostly in-line second-quarter earnings report earlier this month. The eyewear maker had also slashed its sales outlook citing an uncertain macro environment, but Citi analyst Paul Lejuez said he's sticking with the stock. "Overall we believe mgmt took 2022 guidance to a very conservative level that helps limit the risk of future disappointment," he wrote. Lejuez said investors should expect retail growing pains as consumer's navigate a post-pandemic. Still, the analyst says Warby is a "long term market share gainer that will benefit as consumer behaviors normalize." Warby's move to add services like eye exams and products like contacts should create a brand new revenue stream, which is underappreciated according to Lejuez. "We maintain our Buy rating, as we view the lowered guidance as de-risking F22 with opportunity to beat, and we remain optimistic about the long-term growth opportunity," he said. MKM- World Wrestling, Buy rating "2022 outlook improving as are the l-t growth opportunities. ... More importantly, we still see very attractive growth potential over the next several years. ... In an environment where video platforms around the world are engaging in a content arms race, WWE is well-positioned as an independent programming creator, to not only expand its revenue streams but also realize sizable increases in the value of its content." Wabtec- Raymond James, Outperform rating "Multi-year growth algo is accelerating. ... Over a multi-year time frame, we see Wabtec uniquely positioned to capitalize on 1) global decarbonization efforts across the transportation space (enabling growth in Freight + Transit segments), 2) a meaningful locomotive fleet renewal cycle (driving modernizations and new builds) and 3) a large "self-help" margin opportunity. .... All said, after running our detailed risk/reward analysis through, we see a largely favorable upside/downside skew for shares of WAB." XP- Goldman Sachs, Buy rating "Short-term headwinds, but still healthy long-term growth potential; Maintain Buy. ... Growth is still in early stages. ... While the decline in margins in 2Q22 disappointed, this was partly due to a 70% increase in the employee base in 2021, which is still being absorbed, and the employee base is only up 2% YTD, which could imply room for operating leverage. Finally, we think valuation is attractive at 12.0x 2023E P/E with expected EPS growth of 31% in 2024." Warby Parker- Citi, Buy rating "Overall we believe mgmt took 2022 guidance to a very conservative level that helps limit the risk of future disappointment. ... And although many within the industry are dealing with changes in purchase pattern for corrective eyewear, we continue to believe WRBY is a long term market share gainer that will benefit as consumer behaviors normalize. ... We maintain our Buy rating, as we view the lowered guidance as de-risking F22 with opportunity to beat, and we remain optimistic about the long-term growth opportunity." Nio- Deutsche Bank, Buy rating "Overseas expansion [is] charging forward. ... With most investors laser focused on weekly/monthly sales in China, we take a break from that and provide a brief update on recent developments that show NIO pushing forward overseas which we think is an underappreciated aspect of NIO's long term growth prospects. ... We think perhaps NIO's desire to enter the US may be far greater than it appears especially given how competitive the domestic Chinese market is becoming."
