isnt the market itself exactly that?

Long term market rate of return is positive (extremely positive of late), where as casino gambling is EV negative.

But options and futures exist as a short term hedge on equity investment. Combine that with the vig Robinhood takes on the front end in the form of higher contract prices, and you end up with an EV negative return - more consistent with high stakes gambling than equity investing.

I class market trackers as investing rather than gambling.

Sure they can still go down (and by a lot), but it tends to be big events like COVID that do that, and it soon bounced back up again.

If you're investing more than a few percent of your portfolio in any one company, you're probably gambling though. And sure, nVidia look a safe bet today, but if Sam Altman comes out tomorrow and goes "sorry guys, this ain't going anywhere" then you'll lose over half your money before you can blink.

I wouldn't invest on a timeframe of less than a few years either. It's not for boosting your rent money. It's just better than leaving your spare money in cash. If the concept of "spare money" is alien, then it's probably not for you.

I read a forum post many years ago about people that put all their retirement money into some company that was going to be the sole supplier for some components for the iPhone. Apple didn't end up going with them, and the company was relying entirely on that contract. The company went bankrupt, and the people that invested lost all their money.

In the end, why invest in a small number of companies when you can invest in practically all of them? Bogleheads three fund portfolio (total US stock + total world stock + bonds) is very simple yet will beat most actively-managed portfolios over the long run.
