Do NOT Buy SpaceX – Do This Instead (Ad)

SpaceX just went public - and Whitney Tilson, Harvard MBA and 30-year Wall Street veteran, says buying in could be a costly mistake. He calls it among the most overhyped, overvalued large-cap offerings ever pushed onto everyday investors. Tilson believes a rare economic event is approaching - one with serious consequences for your portfolio this summer. He has prepared a free analysis outlining what he sees and the specific steps he recommends taking now.tc pixel

CODE RED: AI Meltdown Imminent? (Ad)

After correctly predicting the 2008 and 2020 stock market meltdowns, I believe this AI company is about to trigger the next crash. The research firm Bernstein Research said this AI company has the power to crash the global economy for a decade, the CEO just issued a CODE RED in an internal memo warning employees they're dealing with a critical situation, and another company executive even implied they might need a government bailout. The last time I saw something like this was in 2008 when I predicted a stock market meltdown just three weeks before Lehman went under.tc pixel
