How it works
This is useful around corporate or index events that attract attention to a position. The event itself does not remove concentration risk. Keep additions, withdrawals and changes in other assets visible when moving from a simple illustration to an actual portfolio calculation.
A simple example
A hypothetical ₹50,000 holding in a ₹10 lakh portfolio is 5%. If it rises to ₹1 lakh while other assets remain ₹9.5 lakh, the total becomes ₹10.5 lakh. The new weight is approximately 9.52%, not exactly 10%.
What to check
- Recalculate the complete portfolio denominator.
- Include cash flows and other asset changes.
- Review concentration after gains as well as purchases.
