A veteran bull who's championed tech giants for years just flipped his script—he's now telling investors to bail out. His warning? What's coming next won't be pretty. "We're entering a Game of Thrones scenario," he argues, suggesting the dominance these companies enjoyed is crumbling. The shift marks a dramatic reversal from someone who rode the wave up, and his timing raises eyebrows across trading desks. Are the glory days of mega-cap tech really over, or is this just another contrarian call that'll age poorly?
