There are no recommendations on when to buy or sell a particular smallcase. It's the investors who decides which theme will work and when to buy or sell. 

Sometimes markets over/under-react to events in the short term which should auto-correct with time. You might make more profit by selling before an event or after. 

However, should the theme of the smallcase you hold completely play out, you will receive a notification on the same.
