Vladimir Lenin was right… (Ad)

The Magnificent 7 could be in for a world of pain… And the insiders know it. It’s why Jeff Bezos just sold $3 billion of Amazon… it’s why Nvidia’s CEO just sold $713 million... and it’s why Zuckerberg just sold $1.3 billion in Meta stock. The financial establishment doesn’t want you to know about this… but a controversial new documentary just pulled back the curtain and exposed what’s really going on. It’s called The Final Frontier.

Including the name of the #1 company to buy.
