$NVIDIA(NVDA.US) soared, CEO Jensen Huang is selling; $Amazon(AMZN.US) rose nicely, and Bezos also sold a large amount.

It's really interesting. On one hand, tech stocks are hitting new highs, while on the other hand, there's constant news of major executives reducing their holdings.

As for the reasons, on one hand, stock prices keep rising, and valuations are becoming increasingly difficult to support with current fundamentals; on the other hand, there's the possibility of increased tax pressure in U.S. society.

Currently, bipartisan consensus in U.S. fiscal policy and the growing passive fiscal spending due to aging are increasing expenditures. Meanwhile, the corporate and individual tax cuts from the Trump era remain, with a few policies expiring in 2024 and most expiring in 2025. If tax pressure increases, we may see more wealthy individuals locking in profits as stock prices hit new highs.
