Introduction

Investing in the stock market can be overwhelming, especially with the myriad of options available. Among the various investment vehicles, total market index funds have gained popularity due to their simplicity, diversification, and low costs. Fidelity offers two standout options in this category: FZROX and FSKAX. While both aim to replicate the performance of the entire U.S. stock market, subtle differences can impact your investment strategy and long-term returns.

This comprehensive comparison will help you understand which fund aligns better with your financial goals, investment horizon, and personal preferences.

Understanding Total Market Index Funds

Total market index funds seek to replicate the performance of a broad stock market index, such as the CRSP US Total Market Index or the Russell 3000 Index. These funds provide investors with exposure to the entire spectrum of publicly traded U.S. companies, ranging from large-cap giants to small-cap growth stocks.

Benefits of Total Market Index Funds

  • Diversification: By holding thousands of stocks, these funds minimize the risk associated with individual stock performance.
  • Low Costs: Passive management typically results in lower expense ratios compared to actively managed funds.
  • Simplicity: Easy to incorporate into various investment strategies without the need for constant monitoring.
  • Market Performance Tracking: These funds aim to match the market’s overall performance, making them suitable for long-term investors.

Considerations

  • Market Risk: While diversified, these funds are still subject to overall market fluctuations.
  • Limited Flexibility: Passive management means the fund won’t adjust holdings based on market conditions.

FZROX vs. FSKAX: Detailed Comparison

While both FZROX and FSKAX aim to cover the entire U.S. stock market, they have distinct characteristics that set them apart. Let’s explore these differences in detail.

Expense Ratios and Fees

Fidelity ZERO Total Market Index Fund (FZROX):

  • Expense Ratio: 0% (ZERO fees).
  • Additional Fees: No minimum investment requirement and no transaction fees within Fidelity accounts.

Fidelity Total Market Index Fund (FSKAX):

  • Expense Ratio: 0.02%.
  • Additional Fees: Slightly higher than FZROX but still among the lowest in the industry. FSKAX may have minimum investment requirements depending on the account type.

Comparison:

  • Cost Efficiency: FZROX offers a clear advantage with its 0% expense ratio, making it an attractive option for cost-conscious investors.
  • Value Added: While FSKAX charges a minimal fee, it still remains highly competitive and offers additional benefits like broader diversification and portability.

Holdings and Diversification

FZROX:

  • Number of Holdings: Approximately 2,631 U.S. stocks.
  • Market Coverage: Focuses on large and mid-cap companies, potentially excluding some smaller companies.
  • Sector Allocation: Mirrors the broader market with significant exposure to technology, healthcare, financials, and consumer discretionary sectors.

FSKAX:

  • Number of Holdings: Approximately 3,875 U.S. stocks.
  • Market Coverage: Includes a wider array of companies, encompassing small-cap stocks that FZROX may exclude.
  • Sector Allocation: Similar to FZROX but with additional exposure to smaller sectors due to increased diversification.

Comparison:

  • Diversification: FSKAX offers broader diversification by including more stocks, particularly in the small-cap segment, which can enhance the fund’s ability to capture a wider market performance.
  • Risk Profile: The inclusion of more small-cap stocks in FSKAX can introduce higher volatility but also potential for greater returns over the long term.

Eligibility and Portability

FZROX:

  • Eligibility: Can only be held within Fidelity accounts.
  • Portability: Limited to Fidelity’s ecosystem, which may restrict investors looking to diversify across different brokerages.

FSKAX:

  • Eligibility: Transferable to other brokerages, offering greater flexibility.
  • Portability: Easily moved between different investment platforms, enhancing its appeal to investors who value liquidity and flexibility.

Comparison:

  • Flexibility: FSKAX provides superior portability, making it a better choice for investors who might want to switch brokerages or manage a diversified portfolio across multiple platforms.
  • Account Consolidation: FZROX is ideal for those who prefer to keep all investments within Fidelity, benefiting from integrated account management and services.

Performance Analysis

Analyzing the performance of FZROX and FSKAX involves looking at their historical returns, risk metrics, and how they behave during different market conditions.

Historical Returns

Since its inception in 2018, FZROX has delivered returns closely tracking the overall U.S. stock market. FSKAX, with its broader diversification, has shown similar performance patterns, with slight variations attributable to the inclusion of additional small-cap stocks.

  • FZROX: Consistently mirrors the market with minimal tracking error.
  • FSKAX: Slightly higher returns during periods when small-cap stocks outperform but may lag when large-cap stocks are leading.

Risk Metrics

  • Volatility: Both funds exhibit similar volatility levels, with FSKAX experiencing slightly higher fluctuations due to its small-cap exposure.
  • Beta: Both have a beta close to 1, indicating that their performance moves in line with the overall market.
  • Alpha: Minimal alpha as both are passive index funds designed to match market performance.

Stability During Market Volatility

During market downturns, both FZROX and FSKAX tend to follow the broader market trends. However, FSKAX’s additional small-cap exposure can lead to more pronounced declines during bearish phases and more significant rebounds during bullish phases.

  • FZROX: Offers stability through its focus on large and mid-cap stocks.
  • FSKAX: Enhanced growth potential but with increased risk due to small-cap inclusion.

Integrating FZROX and FSKAX into a 60/40 Portfolio

A classic 60/40 portfolio balances 60% in equities (stocks) and 40% in bonds, aiming for growth with a moderate risk profile. Both FZROX and FSKAX can serve as the equity component in this strategy.

Option 1: Using FZROX

Bonds Fidelity U.S. Bond Index Fund (FXNAX) 40%

Advantages:

  • Cost Efficiency: 0% expense ratio maximizes net returns.
  • Simplicity: Easy to manage within Fidelity accounts.

Considerations:

U.S. Stocks Fidelity Total Market Index Fund (FSKAX) 60%
Bonds Fidelity U.S. Bond Index Fund (FXNAX) 40%

Advantages:

  • Broader Diversification: More holdings, including small-cap stocks.
  • Flexibility: Portability across different brokerages.

Considerations:

  • Slightly Higher Fees: Minimal expense ratio of 0.02%.
  • Potential for Higher Volatility: Due to small-cap exposure.

Backtesting Results

We conducted a 6-year backtest on both portfolio options using historical data. The results were nearly identical, with FZROX having a slight edge due to its 0% expense ratio. Over extended periods, this fee difference can compound significantly, favoring FZROX for long-term investors.

Key Findings:

  • Return on Investment: FZROX slightly outperformed FSKAX on a net basis.
  • Risk-Adjusted Returns: Both portfolios maintained similar Sharpe ratios, indicating comparable risk-adjusted performance.
  • Long-Term Growth: The difference in returns becomes more pronounced over decades, benefiting FZROX due to zero fees.

Tax Considerations

Investors should be mindful of the tax implications associated with mutual funds. Both FZROX and FSKAX are subject to capital gains taxes when the fund manager rebalances the portfolio or sells securities.

  • Capital Gains: Both funds distribute capital gains to investors, which can be taxable in non-retirement accounts.
  • Dividend Taxes: Dividends are taxable unless held in tax-advantaged accounts.
  • Tax Efficiency: While both funds are relatively tax-efficient, FSKAX’s broader diversification might result in slightly different tax outcomes. It’s essential to consult with a tax professional to optimize tax strategies.

Tax-Advantaged Accounts: Holding FZROX or FSKAX in accounts like IRAs or 401(k)s can defer taxes on dividends and capital gains, enhancing overall tax efficiency.

Dividend Policies and Reinvestment

Both FZROX and FSKAX distribute dividends quarterly, providing a steady income stream aligned with the total market average.

Dividend Reinvestment

  • FZROX: Offers an optional Dividend Reinvestment Plan (DRIP), allowing dividends to be automatically reinvested into the fund.

Conclusion: Choosing Between FZROX and FSKAX
