VX Vanguard Total International Stock Index Fund ETF Shares
VXUS - US9219097683 20.00%
This portfolio is made up of just two broad stock ETFs: one tracking large US companies at 80% and one tracking international stocks at 20%. That means the structure is intentionally simple, relying on wide index funds rather than many individual positions. A setup like this is easy to understand and maintain because each ETF holds hundreds or thousands of underlying companies. The “balanced” risk label here doesn’t mean there are bonds; it reflects moderate equity risk compared with more aggressive all‑stock mixes that lean into narrower themes. Overall, this is a straightforward, equity‑only core portfolio with a clear tilt toward the US market through that 80% allocation.
Growth
From 2016 to 2026, $1,000 in this portfolio grew to about $3,806, which works out to a 14.35% Compound Annual Growth Rate (CAGR). CAGR is like your average speed on a long road trip, smoothing out all the ups and downs along the way. Over this period, the portfolio slightly lagged the broad US market but beat the global market by a noticeable margin. The worst drop, or max drawdown, was around –34% during early 2020, matching the sharp COVID sell‑off. It then recovered in about five months, which is fairly quick historically. Only 35 days made up 90% of returns, showing how a handful of strong days drove much of the long‑term growth.
Projection
The Monte Carlo simulation projects many possible futures for this same portfolio by remixing patterns from historical returns and volatility. Think of it as running 1,000 different “what if” market paths and seeing where a $1,000 investment ends up after 15 years. The median outcome lands near $2,681, with a wide middle band from about $1,703 to $4,217. There’s roughly a 71% chance of ending with more than you started, but the range runs from around $956 to $7,824 in the more extreme cases. This spread highlights uncertainty: even with the same portfolio, outcomes vary a lot. As always, simulations use past data, which can’t fully predict future market behavior.
Asset classes
- Stocks 100%
All of this portfolio sits in one asset class: stocks. There’s no allocation to bonds, cash, or alternatives like real estate funds or commodities. That means the portfolio’s behavior is tightly tied to the ups and downs of global equity markets, with limited dampening from more stable assets. A 100% equity mix historically has higher growth potential but also deeper and faster drawdowns when markets fall. Compared with a multi‑asset benchmark that blends stocks and bonds, this portfolio would typically show higher volatility. The clear upside is simplicity: one type of asset with broad coverage. The trade‑off is that diversification happens within equities only, not across fundamentally different asset classes.
Sectors
- Technology 34%
- Financials 15%
- Industrials 10%
- Consumer Discretionary 9%
- Telecommunications 9%
- Health Care 9%
- Consumer Staples 5%
- Energy 4%
- Basic Materials 3%
- Utilities 2%
- Real Estate 2%
Sector‑wise, the portfolio is clearly tilted toward technology at 34%, with financials, industrials, and consumer areas making up most of the rest. This is quite similar to many broad equity indices today, where tech and tech‑adjacent businesses have grown large in market value. A tech‑heavy weighting can boost returns during innovation‑driven bull markets, but these sectors can also be more sensitive to interest rates, regulation, and sentiment swings. Defensive areas like utilities, real estate, and consumer staples have smaller roles here, so they’re less able to steady returns during risk‑off periods. Overall, the sector mix looks modern and growth‑oriented, aligned with mainstream benchmarks rather than niche themes.
Regions
- North America 81%
- Europe Developed 7%
- Asia Developed 3%
- Japan 3%
- Asia Emerging 3%
- Australasia 1%
- Africa/Middle East 1%
Geographically, about 81% of the portfolio sits in North America, with relatively small slices in Europe, Japan, developed Asia, and emerging markets. That strong US tilt is typical of many investor portfolios and reflects the size and performance of US markets in recent decades. It also means results are highly linked to the US economy, corporate earnings, and the US dollar. Compared with a global market‑cap benchmark, this allocation is more US‑heavy and lighter in non‑US regions. That has worked well over the last decade but does reduce diversification across different economic cycles, policy regimes, and currencies. The international ETF adds some balance, but the US clearly drives overall behavior.
Market capitalization
- Mega-cap 45%
- Large-cap 34%
- Mid-cap 18%
- Small-cap 2%
By market capitalization, the portfolio is dominated by mega‑cap and large‑cap companies, which together account for about 79% of exposure. Mid‑caps add another meaningful slice at 18%, while small‑caps are only 2%. Larger companies tend to be more established, with diversified revenue streams and deeper liquidity, which can reduce individual business risk compared with tiny firms. The trade‑off is that they may not move as explosively as smaller, early‑stage companies in hot periods. This market‑cap profile is very close to broad index norms, so it behaves much like the “market average” in terms of size exposure. Most of the portfolio’s risk and return comes from big, globally recognized firms.

- Vanguard S&P 500 ETF
- Top 10 total 29.13%
Looking through the ETFs to their top holdings, a handful of large US companies stand out: NVIDIA, Apple, Microsoft, Amazon, Alphabet, Broadcom, Micron, Meta, and Tesla together form a meaningful slice of the portfolio. Because some of these show up in both ETFs, they create overlap, which increases exposure to those specific names beyond what two‑fund simplicity might suggest. For example, NVIDIA and Apple alone account for over 11% together in the visible portion. Note that this overlap is based only on each ETF’s top 10 holdings, so the true overlap is probably higher. This concentration means the portfolio’s day‑to‑day moves are strongly influenced by a small set of mega‑cap growth and tech‑related companies.
Factors
Factor exposure here is very balanced: value, size, momentum, quality, yield, and low volatility all sit in the neutral range near 50%. Factors are basically traits—like “cheap vs. expensive” (value) or “steady vs. bumpy” (low volatility)—that academic research links to long‑term performance. A neutral profile means the portfolio behaves similarly to the overall global equity market rather than making a big bet on any single style. For example, there’s no pronounced lean toward high dividend payers, deep value, or small‑cap stocks. This can be helpful if the goal is to track broad market behavior without trying to time which factor will be in favor, accepting whatever mix the market delivers over time.
Risk contribution
-
Vanguard S&P 500 ETF
Weight: 80.00% 82.4% -
Vanguard Total International Stock Index Fund ETF Shares
Weight: 20.00% 17.6%
Risk contribution shows how much each holding drives the portfolio’s overall ups and downs, which can differ from its weight. Here, the S&P 500 ETF is 80% of the allocation but contributes about 82% of total risk. The international ETF holds 20% of the weight and contributes around 18% of risk. Those numbers are close to their weights, so there’s no extreme mismatch where a small position dominates volatility. Still, because there are only two holdings and one of them is so large, the portfolio’s risk is highly tied to that single US ETF. This is a coherent, concentrated core structure rather than a finely sliced blend of many separate risk drivers.
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.
The risk‑return chart shows this portfolio sitting on or very close to the efficient frontier. The efficient frontier is the curve of best possible returns for each risk level using only the current holdings but in different weightings. The current mix has a Sharpe ratio of 0.62, while the maximum‑Sharpe combination of the same two ETFs scores 0.82 with slightly higher volatility. The minimum‑variance mix has the lowest risk but also a lower expected return. Since the current allocation lies essentially on the frontier, it’s making good use of these two holdings for its chosen risk level. In other words, within this simple structure, the trade‑off between risk and return is already efficient.
Dividends
- Vanguard S&P 500 ETF 1.00%
- Vanguard Total International Stock Index Fund ETF Shares 2.50%
- Weighted yield (per year) 1.30%
The portfolio’s overall dividend yield is around 1.3%, blending a lower‑yielding US ETF at about 1.0% with a higher‑yielding international ETF near 2.5%. Dividend yield is the cash income you receive each year as a percentage of your investment, separate from price changes. This level is modest compared with strategies specifically focused on high dividends, but it aligns well with large‑cap global equity indices today. In a portfolio like this, total return mostly comes from a mix of earnings growth, valuation changes, and some dividends rather than income alone. Reinvesting those dividends, even at relatively low yields, can still contribute meaningfully to long‑term compounding over time.
Ongoing product costs
- Vanguard S&P 500 ETF 0.03%
- Vanguard Total International Stock Index Fund ETF Shares 0.05%
- Weighted costs total (per year) 0.03%
The ongoing costs here are impressively low. The S&P 500 ETF charges a 0.03% Total Expense Ratio (TER), and the international ETF charges 0.05%, leading to a blended cost of roughly 0.03%. TER is the annual fee the fund takes to cover management and operations, expressed as a percentage of assets. At these levels, only a tiny slice of returns goes to fees each year. Over long periods, low costs help more of the portfolio’s gross performance show up in your own results. Compared with many actively managed funds or niche products, this cost structure is very competitive and a real strength of the portfolio’s design.
