You aren't buying a "ticker" when you buy NVDA or AAPL.
You are becoming an owner of an operating business. An owner with no boss clocking your time. No responsibility to run payroll or plan meetings. An owner with virtually no responsibility ... other than to check in on things every so often to ensure it is running as you expect.
You even get a say in material business decisions if you want. You regularly get to vote on directors, voice your opinion on pay packages, and sometimes much more!
The best part is that you have the option to exit almost any time, AND you have the option to buy more of the company as well. With almost no transaction costs! No attorney needed, no buy/sell agreement needed. Just a few clicks on a keyboard!
There will be times where the mass freaks out over random political or global events, and you will have the opportunity to buy more of a wonderful company at a drastically reduced price.
There will also be times where strangers will offer you a silly high price to sell, and you can choose to sell none, some, or all of your ownership ... again, with almost zero transaction costs!
The public markets never cease to amaze me.
