I just put my first $500 into SPY using Charles Schwab in an Individual Brokerage account, Im 18 years old, I had been researching stocks for like a month and then this entire thing happend, and even though it's my first time investing into stocks I loook at all of these stocks being down as a great opportunity to get in low. I'm submitting this post because i truly just want advice on anything, (which is partly why I put every piece of information with how I invested my money in the first sentence).
My main goal is to just keep investing about $200 weekly during this firesale, then shave it down to maybe $200 a month after that. My main questions are if I should just invest into SPY or do others like VTI, QQQ, BX or something less "stable", like AAPL, or NKE. I want to be financially stable when I'm older and my econ class is really influencing me with all of these exponential growth graphs, and I know there are a million posts like this on this sub but any help would be greatly apprectiated in any means.
TL;DR: I invested $500 into SPY, what do I do now?
