In Asset Classes TAB, how is the current growth rate defined?

• A. Sum of annual returns
• B. Weighted avg of underlying indices
• C. User-defined constant
• D. Current growth rate solely from a single index

Answer: (B)

The current growth rate is defined as the weighted average of the growth rates of the underlying indices. This means you combine each index’s growth rate according to how much of the asset class is allocated to it, so the overall figure reflects diversification within the asset class. For example, if an asset class is 60% US equities with a growth rate of 7% and 40% international equities with a growth rate of 5%, the current growth rate would be 0.60×7% + 0.40×5% = 6.2%. This approach matches how a real portfolio behaves, since the overall performance comes from the mix of components, not a single index or an arbitrary constant. The sum of annual returns would ignore weights and composition; a user-defined constant would ignore actual market performance; and relying on a single index would fail to capture diversification within the asset class.
