One of the frameworks which has served me well over the years in generating extraordinary returns is to identify companies where one can capture a high-growth phase and re-rating in valuation. There can be many circumstances which lead to this kind of occurrence.

The catalysts could be owing to several reasons, including a change in management or change in the industry structure.
