No

No but my professor said etfs are good.

No

I invested in a couple of stocks a long time ago, I asked my friend who got rich off the stock market which stocks to invest in, I still have those two stocks (except that now they're my mom's stocks, since I transferred them over to her for SSI-related reasons), one seems to have made good gains, while the other is now a penny stock. I also have a few shares in Disney because my grandma gave me a share once for my birthday or possibly Christmas a long long time ago and the stock split a few times since then.

Yes, I do. Mainly for my pension fund.
