An S&P Index fund

I don't know the first thing out investing. You have to have enough money to lose if it happens, unless you have expert knowledge. I won't take the chance with the little I have. (which is not mine, I have to pay it back)

a fat sack :P

I'm probably not the best person from whom to take investment advice. Honestly, the more effort I have put into researching something, the worse the investment has turned out. I bought stock in a sandwich shop once and hit the jackpot when the shop ended up taking off just two weeks later, and the stock literally quadrupled in price. I also had a bunch of GM stock that I sold for $40/share, because I was looking to buy a house. It was 2008. A year later, that stock was worth less than $10, and a year after that, it was worth less than a dollar. On the other hand, I thought investing in bitcoin would be a good idea. I did okay with it at first, but then bought Chinese stock in computer component manufacturers with the bitcoin, after watching the stock steadily grow for several months. A week later, the company in which I invested went bankrupt. I bought another (domestic) stock some years ago after keeping an eye on it for several months, and after I bought it, it plateaued and never paid any dividends, so when I finally sold it years later, I got exactly the price I paid for it. If you have enough cash, though, and you want a more diversified investment, you should probably look into a mutual fund, but whatever you do, don't buy government bonds right now unless you don't want your money - the bond yield curve is inverted right now, so a $50 will be worth $49 when it matures.

AI companies. That industry is gonna burst at the seams.
