As an investor, I often find myself searching for ways to balance risk and reward without constantly monitoring the markets. Asset allocation funds from Fidelity offer a compelling solution by automatically diversifying across stocks, bonds, and other securities. In this article, I explore how these funds work, their historical performance, and whether they fit different investor profiles.

What Are Asset Allocation Funds?
Asset allocation funds pool investor money and distribute it across multiple asset classes based on a predefined strategy. Fidelity offers several variations, including:
- Target-Date Funds – Automatically adjust allocation as the target retirement year approaches.
- Balanced Funds – Maintain a fixed mix (e.g., 60% stocks, 40% bonds).
- Tactical Allocation Funds – Shift allocations based on market conditions.
The primary advantage is diversification, which reduces risk. Modern Portfolio Theory (MPT) suggests that an optimal mix of assets maximizes returns for a given risk level. The expected return E(R_p) of a portfolio can be expressed as:
E(R_p) = \sum_{i=1}^n w_i E(R_i)where w_i is the weight of asset i and E(R_i) is its expected return.
Fidelity’s Approach to Asset Allocation
Fidelity’s asset allocation funds follow disciplined methodologies. Some, like the Fidelity Freedom Funds, use a glide path that becomes more conservative over time. Others, such as the Fidelity Balanced Fund (FBALX), stick to a consistent allocation.
Historical Performance Comparison
Let’s compare three popular Fidelity allocation funds over the past decade:
| Fund Name | 10-Year CAGR (%) | Expense Ratio | Allocation (Stocks/Bonds) |
|---|---|---|---|
| Fidelity Freedom 2040 (FFFFX) | 7.2 | 0.75% | 85/15 |
| Fidelity Balanced (FBALX) | 8.1 | 0.51% | 60/40 |
| Fidelity Asset Manager 50% (FASMX) | 6.4 | 0.68% | 50/50 |

The Fidelity Balanced Fund outperformed due to its tilt toward equities during a bull market. However, higher stock exposure also means higher volatility.
Mathematical Framework: Risk vs. Reward
The Sharpe Ratio measures risk-adjusted returns:
Sharpe\ Ratio = \frac{E(R_p) - R_f}{\sigma_p}where R_f is the risk-free rate and \sigma_p is portfolio volatility.
For FBALX, assume:
- E(R_p) = 8.1\%
- R_f = 2.0\%
- \sigma_p = 10.5\%
Then:
Sharpe\ Ratio = \frac{8.1 - 2.0}{10.5} = 0.58A higher ratio indicates better compensation for risk taken.
Who Should Invest in Fidelity’s Asset Allocation Funds?
These funds suit:
- Passive investors who prefer a hands-off approach.
- Retirement savers using target-date funds.
- Moderate-risk takers who want diversification without extreme swings.
However, active traders might find them restrictive due to limited flexibility.
Tax Efficiency and Costs
Fidelity’s index-based allocation funds (e.g., Fidelity Freedom Index Funds) have lower expense ratios (0.12% vs. 0.75% for actively managed versions). Tax efficiency varies—funds with high turnover generate more capital gains.
Final Thoughts
Fidelity’s asset allocation funds simplify investing but require careful selection based on risk tolerance and goals. While they may not beat the market, they provide stability—a trade-off many investors willingly accept.
