Positions

This portfolio is built around three broad index funds, with roughly seventy percent in a large US stock index, twenty percent in a total international stock index, and ten percent in a US bond index. That structure is simple yet powerful, and it lines up well with many common “core” benchmark mixes. A single dominant US equity holding means the ride will mostly follow the overall US market, with international and bonds smoothing things a bit. This structure is already very clean and disciplined. If anything, the main dialing choice over time is how much to shift between stocks and bonds as goals, age, or comfort with volatility change.

Growth Info

Historically, this mix delivered a compound annual growth rate (CAGR) of about 13.46%, meaning an investment of $10,000 ten years ago would have grown to roughly $35,300 if that rate persisted. That’s strong and consistent with a stock-heavy, index-based approach during a very good decade for markets. The flip side is the max drawdown of about -31.5%, which shows how far it fell from a peak during a bad period. That level of drop is normal for a growth‑tilted allocation but still emotionally tough. It’s worth remembering that these numbers come from an unusually strong era, so future returns may be lower.

Projection Info

The Monte Carlo simulation, which runs 1,000 random “what if” paths using historical return and volatility patterns, shows a median outcome of about 238% cumulative growth over the test horizon. In plain English, the middle-of-the-road path more than triples the starting value, while even the 5th percentile still ends up positive at around 36.2%. This is encouraging, and 985 out of 1,000 paths finishing above zero underscores that the balance of stocks and bonds is reasonable. Still, simulations lean heavily on the past; they cannot predict recessions, wars, or policy changes. Treat them as rough weather forecasts, not guarantees.

Asset classes Info

  • Stocks
    89%
  • Bonds
    10%
  • Cash
    1%

The allocation by asset class is about 89% stocks, 10% bonds, and 1% cash. That’s clearly an equity‑driven mix, and it explains both the strong historic growth and the meaningful drawdowns. In many common benchmarks for “balanced” profiles, stock exposure sits nearer 60–80%, so this portfolio leans more growth‑oriented than its “balanced” label might suggest. The bond slice is doing its job as a shock absorber but is relatively small. If smoother swings become a priority, nudging more into high‑quality bonds or cash over time would usually be the main lever, while long‑term growth‑focused investors might be happy keeping this equity-heavy structure.

Sectors Info

  • Technology
    26%
  • Financials
    14%
  • Consumer Discretionary
    10%
  • Industrials
    9%
  • Health Care
    8%
  • Telecommunications
    8%
  • Consumer Staples
    5%
  • Energy
    3%
  • Basic Materials
    3%
  • Utilities
    2%
  • Real Estate
    2%

Sector exposure is nicely spread: technology is the largest at about 26%, with financials, consumer cyclical, industrials, healthcare, and communication services all making solid contributions. This looks very similar to broad equity benchmarks, which is a positive sign for diversification. A tech tilt is normal for US and global indexes today and has powered returns recently, but it also means extra sensitivity to things like interest rate moves or changes in innovation sentiment. Since you’re using broad market funds rather than picking specific industries, the sector mix will naturally evolve with the market, which is a big advantage for long‑term hands‑off investing.

Regions Info

  • North America
    71%
  • No data
    10%
  • Europe Developed
    8%
  • Japan
    3%
  • Asia Emerging
    3%
  • Asia Developed
    2%
  • Australasia
    1%
  • Africa/Middle East
    1%

Geographic exposure sits around 71% North America, with the rest spread across developed Europe, Japan, other developed Asia, emerging Asia, and small slices in Australasia and Africa/Middle East. This is very much in line with global stock market weights, where the US dominates. That’s a strength because it keeps you close to widely used benchmarks and global economic leadership, but it does leave results heavily tied to the fortunes of one region. The existing international slice still adds meaningful diversification: different currencies, political systems, and economic cycles. If a stronger global balance is ever desired, gradually increasing the non‑US portion would be the obvious dial.

Market capitalization Info

  • Mega-cap
    41%
  • Large-cap
    30%
  • Mid-cap
    16%
  • Small-cap
    1%

The portfolio is strongly tilted to mega and large companies, with about 71% in mega and big caps, 16% in mid caps, and a very small slice in small caps. That’s exactly what broad market index funds usually look like, since the biggest companies dominate market value. This tilt tends to mean more stability and lower company-specific risk versus a portfolio full of small firms, but maybe slightly lower long‑run return potential than a more small‑cap‑heavy mix. For most investors, this structure is a plus: it keeps things close to standard benchmarks and reduces the odds that any single stock or niche segment drives outcomes too much.

Risk vs. return

This chart shows the Efficient Frontier, calculated using your current assets with different allocation combinations. It highlights the best balance between risk and return based on historical data. "Efficient" portfolios maximize returns for a given risk or minimize risk for a given return. Portfolios below the curve are less efficient. This is informational and not a recommendation to buy or sell any assets.

Click on the colored dots to explore allocations.

On a risk–return basis, this mix already looks close to the “efficient frontier,” which is the set of allocations that give the highest expected return for a given level of volatility using the existing set of assets. Since you’re using broad index funds for US stocks, international stocks, and US bonds, the main optimization lever is the exact percentages between these three, not adding new products. Slightly more bonds could move you toward lower volatility but also lower expected return; slightly more stocks would push the other way. “Efficiency” here doesn’t mean perfect diversification or matching every preference, just getting a solid trade‑off given these building blocks.

Dividends Info

  • FIDELITY TOTAL INTERNATIONAL INDEX FUND INSTITUTIONAL PREMIUM CLASS 2.80%
  • Fidelity 500 Index Fund 1.10%
  • FIDELITY U.S. BOND INDEX FUND INSTITUTIONAL PREMIUM CLASS 3.30%
  • Weighted yield (per year) 1.66%

The total yield of about 1.66% comes from a mix of roughly 1.1% from US stocks, 2.8% from international stocks, and 3.3% from bonds. That’s a modest but meaningful contribution to total returns, especially when reinvested automatically. For a growth‑oriented allocation, this level of yield is very normal and suggests that most of the expected return is from price appreciation rather than income. For investors focused mainly on long‑term wealth building, that’s perfectly fine and tax‑efficient. If steady cash flow ever becomes a bigger goal, gradually shifting more into income‑oriented holdings or slightly increasing bond exposure could raise the portfolio’s overall payout without overhauling the core structure.

Ongoing product costs Info

  • FIDELITY TOTAL INTERNATIONAL INDEX FUND INSTITUTIONAL PREMIUM CLASS 0.06%
  • Fidelity 500 Index Fund 0.02%
  • FIDELITY U.S. BOND INDEX FUND INSTITUTIONAL PREMIUM CLASS 0.02%
  • Weighted costs total (per year) 0.03%

The overall cost picture is excellent. Expense ratios around 0.02–0.06% for each fund produce a combined total expense ratio (TER) of roughly 0.03%, which is impressively low. Over decades, even small fee differences compound significantly, so being down in this range is a major structural advantage and fully in line with best practices. It means more of the market’s return ends up in your pocket instead of going to fund managers. There’s no obvious need to chase lower-cost options here, since you’re already in the ultra‑low category. At this point, focusing on allocation and discipline matters far more than shaving another basis point.
