With the ASX200 down 6.5% so far in January and 16.5% from its April 2015 highs, many investors have taken significant losses on their holdings.

Livewire reached out to a selection of fund managers to understand the process they follow if a stock in their portfolio suffers a significant fall. As discussed in some of our contributors’ responses, the decisions you make after a stock has dropped are essential to your long-term performance. While the processes followed vary significantly between managers, what stands out is that the processes are pre-defined and prepared well in advance. This demonstrates that investors need to be proactive rather than reactive.
