Q: What's up with Suncor today? A good buying opportunity for the long run?

Thanks

Q: Good morning! I have a question on investing knowledge in general, and the companies mentioned above are what I will use as my personal example... because I’ve read from the team at 5i that it doesn’t make much sense to hold out on a loss. Please by all means correct me if I am wrong, example: I bought into SU,(I am -28%) and QST, (I am -60%). XBC (I am -59%). This doesn’t bother me nor does it cause me any financial suffering to hold, and I know there is no magical answer... does a young man ride it out and just wait patiently? I love SU AND QST before the pandemic and still enjoy their presence in my portfolio but here I ask myself this, am I missing gaining opportunity in the markets? My money is sitting negative, slowly, slowly coming back, where a I could suffer the loss and get to work else where? Thank you!

Q: Am I missing any major sectors with these stock investments?
Where should I focus if I would like to ensure a diverse portfolio?
Are there any stocks that I should dump?
