I’m looking to get expose to oil stocks and have narrowed it down to these 3
Occidental petroleum - OXY
PBF Energy - PBF
Talos Energy - TALO
All I know about them this far is that Warren buffet has been investing in the first one & Carlos Slim the richest man in Mexico has been investing in the later two.
How can I do a deeper dive to see which one I should be investing in?
