Which fund would be most appropriate for diversification across multiple asset classes, not just stocks?

• A. Index Fund
• B. Asset Allocation Fund
• C. Sector Fund
• D. Balanced Fund

Answer: (B)

Diversifying across asset classes means spreading investments beyond stocks into other categories like bonds, cash equivalents, and sometimes real assets or commodities. An asset allocation fund is designed specifically to do this: it holds a mix of different asset classes and actively rebalances the portfolio to maintain a target allocation that reflects a chosen risk level. This approach directly addresses the goal of broad, multi-asset diversification.

An index fund, by contrast, typically tracks a single market index, usually stocks, so it concentrates risk in equities. A sector fund targets a specific industry, which concentrates risk even more within one corner of the market. A balanced fund does diversify across stocks and bonds, but its allocation is often fixed or follows a simple rule and may not adjust as dynamically to preserve a broader multi-asset mix like an asset allocation fund does.

So, the fund designed to diversify across multiple asset classes and keep that mix aligned with a chosen risk posture is the asset allocation fund.
