Investment in stocks in the PPE/ glove business

 Dear Mr. Tan,

I invested in some PPE/Gloves stocks which were doing very well last year but I didn't sell them.

This year they all stumbled to their lowest level because of the introduction of vaccines.

Although it is paper loss but I felt disheartened.

Should I continue to hold or cut my losses?
