Most people in the world are not American. We have differing retirement plans and invest in local markets, or all sorts of international markets. The NASDAQ is one of many.
Most people reading this will indeed have zero investment in Nvidia.
"One of many"... Nasdaq & Nyse have capitalization equivalent to pretty much the rest of the world.
Most people reading this, if they have any money in any stock exchange, they are directly or indirectly exposed to Nvidia, whether they like it or not.
Absolutely, but capitalisation does not necessarily reflect the quantity of individual investors.
If you're talking about the indirect impact of foreign stock markets on a local markets... Sure, I guess. But that's hardly in the spirit here. Any large company in many countries has an impact on markets local markets when they sway, but rarely in any significant way.
The majority of people on HN are not impacted in any meaningful way by Nvidia's stock price and have no direct (brokerage, retirement fund, etc) investment in them.
The assessments in further up comments that give context here are that we all either invest in Nvida unknowingly or have our employment/compensation tied to them. I highly doubt this is true for the majority of HN users.
Nvidia is buyable by many international retirement plans, and/or affects international companies. It’s really hard to not be invested indirectly in them right now, even internationally unless your country has restrictions
Most people reading this will indeed have zero investment in Nvidia.
