I invested on a recovery starting in March 2020, especially in travel, retail, oil & gas. That's done really well so far. I'm waiting until a full recovery to sell them off.
The market tries to price in events like increased travel after people are shut inside for a year. I expect travel of such magnitude that experts will feel silly predicting it, and will err on the low end. President Biden suggested July 4th as a target date, which allows lots of travel if his information is accurate.
