What Is the Best Long-Term Investment Plan for Children in Nigeria?

For a long-term investment for your three children (10–15+ years), I would not put everything in one place.
Based on your previous interest in MMFs, mutual funds, stocks, and education planning, a combination approach is usually stronger than relying on a single product.
Recommended Structure
1. Equity Fund (60–70%)
Best for long-term growth because children have many years before the money is needed.
Examples:
Stanbic IBTC Asset Management Equity Fund
Chapel Hill Denham Equity Fund
ARM Investment Managers Equity Fund
Why?
Historically outperforms inflation over long periods.
Can withstand short-term market declines because the investment horizon is long.
2. Money Market Fund (30–40%)
Examples:
Stanbic IBTC Asset Management Money Market Fund
ARM Investment Managers Money Market Fund
Why?
Provides stability.
Reduces the impact of stock market volatility.
Keeps part of the money accessible if needed.
Example
If you save ₦30,000 monthly for the three children:
₦20,000 → Equity Fund
₦10,000 → Money Market Fund
Or open separate investment accounts for each child and contribute equally.
What I Would Avoid
Keeping all the money in a savings account for 10–15 years.
Investing everything in an MMF only. MMFs are excellent for safety, but over very long periods they may not grow as much as equity investments.
Unregulated schemes promising very high returns.
If the goal is specifically university education
A 70% Equity Fund + 30% MMF allocation is a strong balance for children who are still young. As they approach university age, gradually move more of the money into MMFs and bonds to protect the accumulated capital.
