Performance Analysis
Historical Returns vs. Benchmark
The fund benchmarks itself against the Russell 1000 Growth Index. Let’s compare its trailing returns:
| Period | Heritage Fund (TWGHX) | Russell 1000 Growth | S&P 500 |
|---|---|---|---|
| 1-Year | +18.3% | +19.1% | +15.2% |
| 3-Year (Annualized) | +7.5% | +8.1% | +6.8% |
| 5-Year (Annualized) | +12.4% | +13.0% | +10.9% |
| 10-Year (Annualized) | +10.7% | +11.2% | +9.8% |
While the fund lags its benchmark slightly, it has outperformed the S&P 500 over most time horizons.
Risk-Adjusted Performance (Sharpe Ratio)
The Sharpe Ratio measures risk-adjusted returns. A higher ratio means better returns per unit of risk.
Sharpe\ Ratio = \frac{(R_p - R_f)}{\sigma_p}Where:
- R_p = Portfolio return
- R_f = Risk-free rate (e.g., 10-year Treasury yield)
- \sigma_p = Portfolio standard deviation
For TWGHX (5-year):
- Annualized Return (R_p): 12.4%
- Risk-Free Rate (R_f): ~2.5%
- Standard Deviation (σ_p): ~16%
Compared to the Russell 1000 Growth Index’s Sharpe Ratio of 0.68, the fund takes on slightly more risk for marginally lower returns.
Expense Ratio and Cost Efficiency
With an expense ratio of 0.97%, TWGHX is more expensive than many index funds but cheaper than some actively managed peers.
| Fund | Expense Ratio |
|---|---|
| TWGHX | 0.97% |
| Vanguard Growth Index (VIGAX) | 0.05% |
| Fidelity Growth Company (FDGRX) | 0.76% |
Does the higher fee justify performance? Given its slight underperformance vs. the Russell 1000 Growth, cost-conscious investors might prefer a cheaper index alternative.
Tax Efficiency
The fund has a turnover ratio of ~45%, meaning nearly half of its holdings change annually. This can lead to capital gains distributions, making it less tax-efficient than low-turnover index funds. Investors in taxable accounts should weigh this carefully.
Who Should Invest in the Heritage Fund?
Pros:
✅ Strong growth focus – Ideal for investors seeking exposure to high-growth sectors.
✅ Experienced management – American Century has a long track record in growth investing.
✅ Consistent long-term returns – Outperforms the S&P 500 over 5+ years.
Cons:
❌ Higher fees – More expensive than passive alternatives.
❌ Benchmark underperformance – Lags the Russell 1000 Growth slightly.
❌ Tax inefficiency – High turnover may lead to capital gains taxes.
Best Fit For:
- Growth-oriented investors willing to pay for active management.
- Tax-advantaged accounts (e.g., IRAs) where turnover isn’t a major concern.
- Those seeking a diversified large-cap growth fund without picking individual stocks.
Final Verdict
The American Century Heritage Fund (TWGHX) is a solid large-cap growth option, but not necessarily a standout. While it has delivered competitive returns, its higher fees and tax implications make it less attractive than low-cost index funds for some investors.
