Building a Simple Long-Term Portfolio
A long-term portfolio should be simple enough to maintain and robust enough to survive different market environments.
This guide introduces a common structure: core + satellite.
1) The Core: Your Default Allocation
The core is the part of the portfolio you plan to hold through most conditions.
Typical core holdings:
- Broad market index funds
- A bond allocation (optional, based on time horizon and risk tolerance)
- Cash buffer (for near-term needs)
The goal is diversification and low fees.
2) The Satellites: Small, Intentional Bets
Satellites are smaller allocations designed to express views or preferences:
- A sector tilt (e.g., healthcare)
- A factor tilt (e.g., value)
- A handful of individual stocks
Keep satellites small enough that being wrong doesn’t blow up the plan.
3) Decide on a Rebalancing Rule
Rebalancing is how you keep risk from drifting.
Two simple rules:
- Calendar-based: rebalance quarterly or annually
- Threshold-based: rebalance when an allocation drifts (e.g., 5% away from target)
4) A Checklist for “Can I Stick With This?”
- Does it fit your time horizon?
- Would you be comfortable holding it during a 20–40% market drop?
- Are your largest positions intentional?
- Are fees low and the plan easy to maintain?
Summary
A good portfolio is one you can hold through volatility. Start with a diversified core, add small satellites only if you have a reason, and rebalance with a simple rule.
