What is this stock? It’s Nebius (NASDAQ: NBIS). Here’s why he might have bought it. <\/p>\n
Nebius has had an incredible 2026 and is up nearly 200% this year. It had a major dip at the end of July, but that doesn’t matter. <\/p>\n These filings only include holdings as of June 30, so they wouldn’t reflect whether Mandel bought the July dip, but if he bought in April, he’s still up a lot on his initial investment. Nebius caught fire throughout the summer and emerged as one of the best stock picks of 2026, mainly because of its growth. However, there are plenty of signs that Nebius can continue this for the foreseeable future, making it still a great stock to consider owning. <\/p>\n Nebius operates in the neocloud space and is an AI-focused cloud computing provider<\/a>. Right now, there is a major shortage of AI computing power, and any company that has access to computing capacity is in a great spot. To sweeten the deal, Nebius is a preferred partner of Nvidia\u00a0and gains early access to cutting-edge technology. This makes it a top provider to consider, as Nebius will always have the latest and greatest products. <\/p>\n Nebius has signed deals with several of the major AI hyperscalers to rent them computing power, and this is leading to jaw-dropping growth. In Q2, Nebius grew revenue by 454% year over year. That number wasn’t boosted by an acquisition or one-time effect; that’s real growth coming from rapidly expanding its computing capacity. It’s also not a one-off quarter, either. Analysts expect 523% growth for the second half of 2026 and 258% growth for 2027.\u00a0With AI computing demand only expected to increase,<\/a> this makes Nebius one of the best options in terms of pure growth in the AI space. <\/p>\n Although Nebius’ stock has about tripled in 2026, I still think it’s a phenomenal investment to make, and you should consider following billionaire Stephen Mandel’s lead and purchasing shares. <\/p>\n Should you buy stock in Nebius Group right now? <\/p>\n Before you buy stock in\u00a0Nebius Group, consider this: <\/p>\n The Motley Fool\u00a0Stock Advisor\u00a0analyst team just identified what they believe are the\u00a010 best stocks<\/a>\u00a0for investors to buy now\u2026 and\u00a0Nebius Group\u00a0wasn’t one of them.\u00a0The 10 stocks that made the cut are built for long-term growth and could produce monster returns in the coming years. <\/p>\n Consider when\u00a0Netflix\u00a0made this list on December 17, 2004… if you invested $1,000 at the time of our recommendation,\u00a0you’d have $429,223!*\u00a0Or\u00a0when\u00a0Nvidia\u00a0made this list on April 15, 2005… if you invested $1,000 at the time of our recommendation,\u00a0you’d have $1,318,055!* <\/p>\n That performance is why people listen.
