Reporting Trampoline

How often this reporting season have we seen companies report with good numbers and outlook statements only to be punished on the day. Vocus today have reported with a very positive performance and even a special dividend to see only the sellers move in. Although I cannot explain this pattern (one can only speculate) I suspect Vocus will be following the same trampoline effect that others have experienced. Great result, drop in price only to rebound to new highs. CGF, FSA this week alone to name just a couple following this pattern.
