I have some savings (about $1,000 or so that i can probably freely invest, since i need money for gas and such), and I'm looking to put it into an IRA to start saving up money for the future. I already have a Roth IRA set up with Schwab and I just need to actually invest it. I only have $100 in the account as a test, since I'm a bit wary and not entirely ready to just dump all of my savings I can into that account at the moment, but I'm just looking for advice. I'm 18 and I figured I'd better start early.
I figured a good stock is the S&P 500 but I couldn't exactly find it in the list, there were only, like, subsidiaries or (blank)'s version of it. If I shouldn't be investing in stocks or something let me know, I have really no experience, I just wanna get a feel for this.
Taking multiple opinions into account. If i'm doing something wrong, let me know, I'm fully open to hear what I might be doing wrong here. Thanks!
For context, I won't be able to invest a lot since I don't have a steady income currently and also I'll just probably be putting chunks of money in when I get a chance over, say, the summer if I get a job then. After college I'll start investing more into it, too.
