Hi Rajat,
Selling one's position will be dependent on your own unique investor profile. It'll depend on numerous factors - one of which is tax selling losses to offset capital gains. Tax strategies are very unique and we recommend talking to a tax specialist. That being said, myself and Dan are both not fans of the oil & gas industry in general - at least over the long-term. We understand fossil fuels will not be going anywhere in the near and medium term, but there is no stopping the shift to renewables. This is why we are no longer putting fresh capital in these areas.
However, we are both holding producers. I am holding Suncor and I know Dan is holding CNQ - both are best in class but CNQ has really pulled away from SU as the BEST oil stock to own - at least in our opinion. Given this, CNQ is likely to benefit from the economy re-opening and higher oil prices. That being said, oil prices have been highly volatile and even with a vaccine it may take a couple of years for oil demand to reach 2019 levels (if it ever does).
Bottom line, we think that CNQ is the best of any of them to hold in this environment. I can't speak for Dan, but personally I am holding on to SU for a little longer and will likely be exiting my position at some point in 2021. Of note, I don't hold it in a non-registered account so I have no tax implications.
