$NVDA now makes up 5.21% of the MSCI All Country World Index — basically at an all-time high.

To put that in perspective: Nvidia alone is bigger than the entire Japanese stock market (5.16%) and more than double Germany, France, or China's weight in the index.

This number has more than doubled since last year.

One company. Larger than entire countries. That's where we are right now.

The ACWI tracks ~85% of global equities across 47 markets. So when one stock carries this much weight, it's not just a U.S. story anymore — it's a global portfolio story.

If Nvidia sneezes, the whole world catches a cold.
