Missed Nvidia in 2009? This Rare Signal Is Flashing Again.\u00a0In 2009, a “Double Down” signal flashed for a little-known chipmaker called Nvidia.\u00a0For the first time in years, that same “Total Conviction” signal is flashing for a company 1\/100th the size of Nvidia.\u00a0Continue \u00bb<\/a> <\/p>\n Despite the praise for Musk and Starlink, Ackman says he isn’t touching SpaceX right now because of one key concern. <\/p>\n SpaceX hasn’t reported its first earnings as a public company yet (that’s happening on Aug. 4), but we can look at its 2025 earnings to get a sense of how expensive the stock is. <\/p>\n SpaceX made $18.7 billion in 2025, and at the time of writing, its market cap is $1.49 trillion. That’s a trailing price-to-sales (P\/S) ratio of about 79. For perspective, the “Magnificent Seven” stock with the highest trailing P\/S ratio is Nvidia, sitting at 18.7 — about a quarter that of SpaceX. <\/p>\n Good companies don’t always make good investments when prices are too high, and that seems to be the case with SpaceX right now. When a company is priced for perfection, anything short of high-level execution could (and often does) result in sharp pullbacks or downturns. <\/p>\n Ackman also noted that an extremely high valuation also limits some of SpaceX’s upside right now. It’s much harder to double in value when you’re valued at $1.49 trillion (a top 10 public company in the world) versus $100 billion or so. <\/p>\n Will Ackman ever buy SpaceX shares? <\/p>\n The rule on Wall Street is never say never, so we can’t definitively say whether Ackman and Pershing Square will eventually scoop up SpaceX shares. However, Ackman noted that SpaceX wasn’t a part of the plan right now because the company doesn’t have the “degree of predictability” that Pershing Square is looking for. <\/p>\n That said, SpaceX is still very early in its public tenure, and with Ackman calling Musk the “most talented technologist, entrepreneur of our generation,” you’d have to think that, with the right pricing, Ackman would find value in owning SpaceX shares. <\/p>\n Ackman prizes value and a good price in investments, but it seems it will be a while before SpaceX reaches that point, especially while it’s still unprofitable. With a high-profile initial public offering (IPO) like SpaceX, it’s often best to let the dust settle<\/a> before making an investment decision. That’s the route I’m taking. <\/p>\n Should you buy stock in Space Exploration Technologies right now? <\/p>\n Before you buy stock in\u00a0Space Exploration Technologies, 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\u00a0Space Exploration Technologies\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 $397,081!*\u00a0Or\u00a0when\u00a0Nvidia\u00a0made this list on April 15, 2005… if you invested $1,000 at the time of our recommendation,\u00a0you’d have $1,166,221!* <\/p>\n That performance is why people listen.
