First, let's just look at the simple chart for Nvidia (NVDA). The stock's old high at $153 (red bar) should provide support. The 40% downturn that occurred in the first four months of 2025 is history.

Nvidia CEO Jensen Huang sold 225,000 shares worth about $37 million as part of a prearranged trading plan, according to CNBC.

NVIDIA might have clinched the world-first $4 trillion crown, but Microsoft could be hot on its heels.
