Understanding Fidelity Index Fund Investing: Essential Definitions
Before analyzing specific Fidelity index funds, understanding key investment concepts helps investors make informed allocation decisions.
What is an Index Fund?
An index fund is a passively managed investment fund designed to replicate the performance of a specific market benchmark.
Index funds hold all or representative samples of securities in their target index, minimizing active management and associated costs. This passive approach delivers market returns minus minimal expenses.
Fidelity’s index funds track benchmarks including the S&P 500, Total Stock Market Index, and proprietary Fidelity indexes. The funds automatically adjust holdings when index compositions change.
What is a Zero-Fee Index Fund?
A zero-fee index fund charges no expense ratio, meaning investors pay absolutely nothing in management fees.
Fidelity pioneered zero-fee index funds in 2018 with funds charging 0.00% expense ratios. These funds generate no direct revenue from investors, subsidized by other Fidelity business lines.
Zero-fee funds provide identical market exposure as competing funds charging 0.03-0.04%, creating pure cost savings. Over decades, eliminating even tiny fees compounds significantly.
What is the Fidelity Contrafund?
The Fidelity Contrafund is an actively managed mutual fund focused on growth stocks, famous for decades of market-beating performance.
Managed by legendary investor Will Danoff since 1990, Contrafund employs fundamental research to identify undervalued growth companies. The fund takes contrarian positions, hence the name.
With over $175 billion in assets, Contrafund ranks among the world’s largest actively managed funds. The fund’s long-term outperformance justifies its 0.86% expense ratio.
What is a Money Market Fund?
A money market fund invests in short-term, high-quality debt securities like Treasury bills and commercial paper, providing stability and liquidity.
Money market funds aim to maintain $1.00 net asset value per share while generating modest income. These funds serve as cash alternatives for parking money between investments.
Fidelity’s Cash Reserves (FDRXX) offers 4.00% yield with zero expense ratio, providing competitive returns on idle cash without fees.
What is an Expense Ratio?
The expense ratio represents the annual fee an investment fund charges, expressed as a percentage of assets invested.
For example, a 0.015% expense ratio means you pay $1.50 annually per $10,000 invested. Fidelity’s index fund expense ratios range from 0.00% to 0.086%, dramatically lower than industry averages.
Lower expense ratios directly increase investor returns. A fund earning 10% with 0.015% expenses delivers 9.985% to investors, while one charging 0.50% delivers just 9.50%.
What is a Strategic Advisers Fund?
Strategic Advisers Fidelity funds provide professional portfolio management and asset allocation through Fidelity’s advisory subsidiary.
These actively managed funds of funds allocate across Fidelity’s mutual fund lineup based on market conditions and strategic positioning. Strategic Advisers charges higher fees for this active management.
The Strategic Advisers U.S. Total Stock Fund offers 4.31% yield through dividend-focused total market allocation. The 0.40% expense ratio covers active management overlay.
What is Fractional Share Investing?
Fractional share investing allows purchasing partial shares rather than requiring whole shares.
Traditional investing requires buying full shares, potentially leaving cash idle. Fractional shares enable investing exact dollar amounts like $100, purchasing 0.42 shares if the fund trades at $238.
Fidelity supports fractional shares across all mutual funds, enabling precise automatic investments. Investors can invest every dollar without cash drag from uninvested balances.

Assets Under Management: $175.5 billion (shared with FCNTX)
Dividend Yield: 4.22%
Expense Ratio: 0.49%
Minimum Investment: $0
Number of Holdings: 300+

Best Fidelity Index Fund #5: Fidelity Contrafund (FCNTX)
Assets Under Management: $175.5 billion (shared with FCNKX)
Dividend Yield: 4.19%
Expense Ratio: 0.86%
Minimum Investment: $0
Number of Holdings: 300+
The Fidelity Contrafund is the retail share class of one of America’s most successful actively managed mutual funds.
FCNTX charges 0.86% annually, significantly higher than FCNKX’s 0.49%. Investors with access to K shares should choose FCNKX for identical holdings with lower expenses.
Despite higher fees, Contrafund has consistently outperformed the S&P 500 over long periods. Will Danoff’s exceptional stock-picking has justified the higher expense ratio through alpha generation.
The 4.19% dividend yield matches FCNKX within rounding differences. Holdings and management strategy are identical across Contrafund share classes.
Top 10 Holdings:
- Amazon.com Inc. (AMZN) – 5.8%

- Meta Platforms Inc. (META) – 4.8%

Performance History: Since Danoff took over in 1990, Contrafund has delivered approximately 13% average annual returns, significantly outperforming the S&P 500’s 10% long-term average.
A $10,000 investment in 1990 would have grown to over $800,000 by 2024, demonstrating the power of consistent outperformance compounding over decades.
This exceptional track record makes Contrafund one of the best-performing large actively managed funds. However, past performance doesn’t guarantee future results.
Best Fidelity Index Fund #6: Fidelity Total Market Index Fund (FSKAX)
Assets Under Management: $120.5 billion
Dividend Yield: 0.93%
Expense Ratio: 0.015%
Minimum Investment: $0
Number of Holdings: 3,700+

With $120.5 billion in assets and a 0.015% expense ratio matching FXAIX, FSKAX offers the most cost-effective total market exposure available. The fund competes directly with Vanguard’s VTSAX.
The 0.93% dividend yield is lower than S&P 500 funds due to FSKAX’s small-cap exposure. Smaller companies pay lower dividends, focusing capital on growth investments.
Top 10 Holdings:

- Apple Inc. (AAPL) – 5.5%

Total Market Advantages: FSKAX eliminates the need for separate large, mid, and small-cap allocations. One fund provides complete U.S. equity diversification.
Small and mid-cap stocks historically outperform large-caps over long periods. FSKAX captures this small-cap premium while maintaining large-cap core exposure.
The fund automatically rebalances as market capitalizations change, maintaining proper weights without investor intervention. This systematic approach ensures consistent total market tracking.
Best Fidelity Index Fund #7: Fidelity Series Total Market Index Fund (FCFMX)
Assets Under Management: $90.9 billion
Dividend Yield: 1.16%
Expense Ratio: 0.00%
Minimum Investment: $0
Number of Holdings: 3,700+

FCFMX provides identical total market exposure to FSKAX but charges absolutely no expense ratio. The zero-fee structure makes FCFMX the lowest-cost total market fund available anywhere.
With nearly $91 billion in assets, FCFMX demonstrates significant investor adoption of Fidelity’s zero-fee innovation. The fund competes aggressively with Vanguard’s VTSAX charging 0.04%.
The 1.16% dividend yield exceeds FSKAX due to fee calculation differences. Holdings and tracking are virtually identical across Fidelity’s total market funds.
Top 10 Holdings:
- Microsoft Corporation (MSFT) – 5.9%
- NVIDIA Corporation (NVDA) – 5.7%
- Apple Inc. (AAPL) – 5.5%
- Amazon.com Inc. (AMZN) – 3.2%
- Meta Platforms Inc. (META) – 2.4%
- Alphabet Inc. Class A (GOOGL) – 2.1%
- Broadcom Inc. (AVGO) – 2.0%
- Tesla Inc. (TSLA) – 1.8%
- Alphabet Inc. Class C (GOOG) – 1.7%

Over 30 years, eliminating even 0.04% in fees creates thousands in additional wealth. FCFMX’s zero-fee structure maximizes long-term compound growth.
Fidelity Index Funds vs. Vanguard Index Funds
Understanding key differences between Fidelity and Vanguard index funds helps investors optimize their passive investing approach.
Expense Ratios
Fidelity offers lower expense ratios on flagship index funds, with FXAIX and FSKAX charging 0.015% versus Vanguard’s 0.04%.
This 0.025% annual difference saves $25 per $100,000 invested. Over decades, these savings compound significantly, potentially adding tens of thousands to retirement balances.
Fidelity also offers multiple zero-fee funds (FDRXX, FCFMX) that Vanguard doesn’t match. Zero fees represent the ultimate cost efficiency.
Minimum Investments
Fidelity requires no minimum investments across all index funds. Investors can start with $1 versus Vanguard’s $3,000 Admiral Shares minimums.
This accessibility advantage allows younger investors and those with limited capital to access low-cost index investing immediately. Vanguard’s minimums create barriers to entry.
Zero minimums also enable precise dollar-amount investing through fractional shares. Investors can invest exactly $500 without cash drag from partial share limitations.
Fractional Shares
Fidelity supports fractional shares across all mutual funds, enabling precise dollar-amount investments.
Vanguard also supports fractional shares, maintaining parity with Fidelity. Both firms enable automatic investment programs using exact dollar amounts.
Fractional shares eliminate cash drag from uninvested balances. Every dollar goes to work immediately rather than waiting to accumulate full shares.
Trading and Platforms
Fidelity provides superior trading platforms and research tools compared to Vanguard’s more basic interface.
Active traders appreciate Fidelity’s Active Trader Pro platform with advanced charting and analysis. Vanguard focuses on buy-and-hold investors with simpler tools.
Fidelity’s customer service generally receives higher ratings than Vanguard. Phone support, branch access, and digital tools create better customer experiences.
Fund Selection
Vanguard offers broader international and sector fund selections. Fidelity compensates with strong actively managed options including Contrafund.
Both firms provide comprehensive U.S. equity coverage. Vanguard leads in international fund variety while Fidelity excels in active management.
Investors requiring specialized exposures may find better options at Vanguard. Core equity investors find everything needed at Fidelity.
Building Complete Portfolios with Fidelity Index Funds
Investors can construct well-diversified portfolios using only Fidelity index funds across multiple strategies.
Two-Fund Simplicity
A minimal portfolio combines FSKAX (80%) with FXAIX (20%) for 100% U.S. equity exposure.
This simple allocation provides total market coverage through FSKAX with S&P 500 tilt via FXAIX. The combination suits aggressive investors comfortable with full equity exposure.
Rebalancing annually maintains target allocations. The two-fund approach minimizes complexity while capturing comprehensive U.S. market returns.
Three-Fund Classic
The traditional three-fund portfolio allocates across FSKAX (60%), international stocks (20%), and bonds (20%).
Fidelity doesn’t appear in this data with strong international options, so investors might supplement with Vanguard’s VTIAX or iShares’ IXUS for international exposure.
The three-fund approach provides global diversification with fixed income stability. This balanced allocation suits moderate-risk investors.
Contrafund Enhancement
Growth-focused investors might allocate 50% FSKAX, 30% FCNKX (Contrafund K), and 20% FXAIX.
This strategy combines passive total market exposure with active management from Will Danoff’s Contrafund. The allocation seeks alpha from Danoff’s stock-picking while maintaining broad diversification.
Higher fees from Contrafund are offset by potential outperformance. Historical data suggests Danoff has justified his fees through consistent alpha generation.
Cash Reserve Strategy
Conservative investors can allocate 70% FSKAX, 20% FXAIX, and 10% FDRXX (Cash Reserves).
The cash allocation provides liquidity for opportunities and reduces portfolio volatility. FDRXX’s 4.00% yield generates meaningful income on defensive holdings.
This approach suits investors nearing retirement or those wanting flexibility to deploy cash during market corrections.
Tax Optimization with Fidelity Index Funds
Strategic fund placement across account types maximizes after-tax returns and minimizes tax liability.
Tax-Advantaged Accounts
Hold Fidelity index funds in Roth IRAs for tax-free growth and withdrawals after age 59½ and five years.
Traditional IRAs and 401(k)s provide tax-deferred growth with potential current-year tax deductions. All withdrawals are taxed as ordinary income.
Tax-advantaged accounts eliminate annual tax drag from dividends and capital gains. Funds compound faster without tax interference.
Taxable Account Strategies
In taxable accounts, Fidelity index funds provide superior tax efficiency through low turnover and minimal capital gains distributions.
FSKAX and FXAIX typically distribute negligible capital gains annually. Their buy-and-hold approaches defer taxes until investors sell shares.
Tax-loss harvesting opportunities arise during market declines. Selling at losses and immediately purchasing similar funds captures tax benefits while maintaining exposure.
Contrafund Tax Considerations
Active funds like Contrafund generate higher capital gains distributions than passive index funds due to frequent trading.
Hold Contrafund in tax-deferred accounts like traditional IRAs to avoid annual taxes on distributions. This placement maximizes after-tax returns from active management.
In taxable accounts, passive funds like FSKAX and FXAIX provide better tax efficiency than Contrafund. Reserve active funds for retirement accounts.
Asset Location Optimization
Place tax-inefficient investments like bonds and REITs in tax-deferred accounts. Hold tax-efficient index funds in taxable accounts.
This asset location strategy minimizes total portfolio taxes. Bond interest taxed at ordinary rates belongs in IRAs while qualified dividend stocks fit taxable accounts.
Optimal asset location can improve after-tax returns by 0.5-1.0% annually, adding hundreds of thousands to lifetime wealth.
Fidelity Index Funds vs. Active Management
Comparing Fidelity’s index and active funds demonstrates different approaches to wealth building.
Cost Differences
Index funds like FSKAX charge 0.015% versus Contrafund’s 0.86%, creating 0.845% annual cost differences.
On $100,000 invested over 30 years at 10% returns, this cost difference equals approximately $240,000 in reduced ending wealth from higher fees.
Lower costs represent guaranteed relative outperformance. Every dollar saved in fees compounds into additional wealth.
Performance Comparison
Contrafund has historically outperformed the S&P 500 under Will Danoff’s management, justifying higher fees through alpha generation.
However, 90% of actively managed funds underperform their benchmarks over 15-year periods. Contrafund represents the exceptional 10% rather than the rule.
Index funds guarantee market-matching returns minus minimal fees. Active funds offer potential outperformance with high risk of underperformance.
Risk and Predictability
Index funds provide predictable market returns without manager risk. Performance tracks benchmarks systematically.
Active funds depend on manager skill and can experience style drift or performance collapse. Manager departures create uncertainty.
Investors seeking predictable outcomes prefer index funds. Those willing to accept manager risk may allocate to proven active managers like Danoff.
Portfolio Role
Use index funds as core holdings providing broad market exposure. Consider active funds like Contrafund as potential enhancement allocations.
A balanced approach might allocate 70-80% to index funds with 20-30% to select active managers with long-term outperformance records.
This strategy captures market returns through low-cost indexing while seeking alpha through proven active management.
Risks to Consider with Fidelity Index Funds
While Fidelity index funds offer compelling advantages, investors should understand inherent risks before allocating capital.
Market Risk
Index funds provide no downside protection during market declines. When markets fall 20%, index funds fall approximately 20%.
Active managers can theoretically reduce exposure during downturns. Index funds remain fully invested regardless of market conditions.
Long-term investors can tolerate short-term volatility. Shorter time horizons require more conservative allocations including bonds and cash.
Concentration Risk
Market-cap weighting concentrates portfolios in the largest stocks, creating top-heavy exposure.
FXAIX’s top 10 holdings represent over 40% of assets. Technology stocks comprise 35%+ of the portfolio.
This concentration means index funds depend heavily on mega-cap tech performance. Sector diversification is limited by natural market weights.
Zero-Fee Sustainability
Fidelity’s zero-fee funds operate as subsidized loss leaders. The company could eliminate zero-fee offerings if business economics change.
While unlikely in the near term, investors should understand zero-fee funds aren’t permanently guaranteed. Fidelity retains flexibility to adjust pricing.
However, competitive pressure and brand reputation make fee increases unlikely. Vanguard’s low-cost structure forces Fidelity to maintain competitive pricing.
Tracking Error
Small differences between fund returns and index returns create tracking error, typically 0.02-0.10% annually.
Tracking error arises from cash holdings, sampling techniques, and trading costs. Perfect index replication is mathematically impossible.
Fidelity’s tracking error ranks among the industry’s lowest. Investors should expect minor underperformance equal to expenses plus fractional tracking error.
Conclusion
Fidelity index funds represent industry-leading passive investing options, combining ultra-low costs, zero minimums, and one of the most trusted brands in finance.
The 7 best Fidelity index funds ranked by assets range from $90.9 billion to $723 billion, with FXAIX commanding the largest S&P 500 fund assets. Expense ratios of 0.00-0.015% for core index funds dramatically undercut competitors.
FXAIX and FSKAX serve as ultimate core holdings, providing S&P 500 and total market exposure respectively. FDRXX offers competitive cash management with zero fees.
Contrafund provides active management option for investors seeking potential outperformance. Will Danoff’s three-decade track record demonstrates exceptional stock-picking ability.
Zero minimum investments and fractional share support democratize access to low-cost index investing. Investors can start with $1 rather than facing $3,000 barriers at competitors.
Understanding index fund mechanics, tax efficiency, and portfolio construction strategies helps investors maximize wealth accumulation through Fidelity’s low-cost platform.
