Position sizing
Larger positions should be reserved for higher-conviction names with stronger balance sheets and cleaner earnings trends.
Stop-loss discipline
A stop-loss is a risk rule, not a prediction. Define loss tolerance before entering, not after price moves against you.
Avoid revenge trading
After losses, reduce size and reset your process. Chasing quick recovery often compounds damage.
Simple illustration
Risk management is your seatbelt; it does not stop accidents, but it limits damage when they happen.
Worked example
You plan to invest ₦500,000.
- Set max loss per position (for example 1-2% of total capital).
- Size each position so a wrong call cannot heavily damage the portfolio.
- Decide exit rule before entry and follow it consistently.
Takeaway: Survival first, growth second.
