What stock(s) did you invest solely due to a unique element(s) resulting as one of your biggest gains?

Knowledge and experience appreciated…

I am researching companies slowly building my portfolio in stocks after I turned over losses from COVID that were long overdue. I work full time and I am mom of a toddler. As I mentioned above, I am slowly building my portfolio to earn returns from losses and invest in short and long term stocks. I enjoy the DD aspect. Specifically, I perform AML DD and research future eps growth on companies.

Here is my portfolio:
1. GOOG
2. GOOGL
3. BWXT
4. DDOG
5. NU
6. RKLB
7. TSLA
8. NXE
9. RILY
10. SE
11. RUN
12. DKNG
13. ELF
14. AMZN
15. SHOP

Young and old Redditors, name the stock(s) and the unique element(s) on why you chose this/these winner(s)? (i.e., eps growth rate, pe ratio, revenue, and debt)?
