thoughts on RGA and MKL

i recently started investing in stocks in september and a family friend recommended a few stocks to me: GOOGL, AAPL, RGA, MKL, and NVDA. i obviously don’t expect any of my stocks to sky rocket because it’s only been a few months, but google and apple are the only stocks that are doing well. i have hope in nvda, but im not too sure about the other two. if anyone is familiar or has any idea how well RGA and MKL would do, i’d appreciate any thoughts you guys have.
