At Investak, we do not recommend when to buy or sell a particular Stak. It's the user who decides which theme will work and when to buy or sell. At Investak, stock selection for a theme is a result of well documented research process and we ensure that the selected stocks aptly represent the particular theme. Sometimes the market over/under reacts to events in short term which should auto correct with time. You might make more profit by selling before an event or after. We do send a notification when we think the theme has completely played out or factors driving a particular idea have changed.
