Portfolio Construction

Series 6 is not a full portfolio-theory exam, but it does expect the candidate to understand diversification and concentration risk at a practical level. A product recommendation should fit inside the customer’s broader holdings and planning objective. The representative should think about how the position affects risk spread, income mix, liquidity, and overall strategy.

The exam often rewards simple portfolio reasoning. A customer heavily exposed to one asset class, one sector, or one tax treatment may benefit from a different recommendation than a customer whose assets are already well diversified. The stronger answer usually treats the recommendation as part of a portfolio, not as a standalone sale.

Key Takeaways

• Series 6 portfolio-construction questions focus on diversification and fit, not advanced optimization math.
• The best answer usually asks how the recommendation affects the customer’s overall allocation and concentration risk.
• A product can be sound on its own and still be wrong in the customer’s broader portfolio context.
