VO Vanguard S&P 500 ETF
VOO - US9229083632 90.00% -
FU Futu Holdings Ltd
FUTU - US36118L1061 10.00%
This portfolio is extremely simple: about 90% sits in a broad US market ETF tracking large companies, and 10% is in a single growth stock, Futu Holdings. That structure is basically a “core and satellite” setup, where the ETF is the foundation and the single stock is the satellite bet. Simplicity like this is helpful because it’s easy to understand what’s driving returns and risk. The tradeoff is that one individual company still has a noticeable influence on overall ups and downs. A general takeaway is that this kind of layout can work well if the satellite position size matches how much extra risk and drama someone is really comfortable with.
Growth
Historically, this portfolio has been very strong: $1,000 grew to about $3,534, with a compound annual growth rate (CAGR) near 19.6%. CAGR is just the “average yearly speed” of growth over the whole period. That beat both the US and global markets by a healthy margin, which is a big positive. The flip side is a max drawdown of roughly -44%, meaning the worst peak-to-trough drop was almost half the value. That’s a tough ride emotionally. Past results don’t guarantee the future, especially when one stock is involved, but they do show this mix has rewarded investors who tolerated deep but temporary setbacks.
Projection
The Monte Carlo projection uses past return and volatility patterns to randomly simulate many possible 15‑year futures. Think of it as running 1,000 alternate timelines where returns bounce around differently each time. The median outcome more than doubles the money to around $2,839, but the range is wide: roughly $957 to $7,151 in most scenarios. That spread shows how uncertain long‑term investing can be, even with good historical results. Importantly, simulations lean on the past, which may not repeat, especially for a concentrated stock. A sensible takeaway is to treat these numbers as rough weather forecasts, not guarantees, and to focus on staying invested across market cycles rather than chasing the top of the range.
Asset classes
- Stocks 100%
All of the portfolio is in stocks, with no bonds, cash-like instruments, or alternative assets. That 100% equity stance is classic “growth investor” territory: the goal is long‑term appreciation, accepting bigger short‑term swings. Stocks historically offer higher average returns than bonds, but with sharper drawdowns and more emotional turbulence. The benefit is straightforward growth potential; the cost is the ride can be very bumpy at times. For someone with a long horizon and stable income elsewhere, this can be appropriate. For anyone with shorter‑term spending needs, adding other asset classes is one common way people try to smooth the journey and reduce the impact of a bad few years.
Sectors
- Technology 30%
- Financials 21%
- Telecommunications 10%
- Consumer Discretionary 9%
- Health Care 9%
- Industrials 8%
- Consumer Staples 5%
- Energy 3%
- Utilities 2%
- Real Estate 2%
- Basic Materials 2%
Sector-wise, there’s a clear tilt toward technology at about 30%, with financials second at 21%, and the rest spread across consumer, health care, industrials, and smaller slices of energy, utilities, real estate, and materials. This is more tech‑heavy than a perfectly even sector mix, but still reasonably balanced by broad market standards. Tech leadership can be great during innovation booms and when growth stocks are in favor, yet it tends to be more sensitive to interest rates and sentiment shifts. The positive here is that the portfolio’s sector spread is broadly aligned with major indices, which is a strong indicator of solid diversification, even if tech and financials are the main engines.
Regions
- North America 89%
- Asia Developed 10%
Geographically, the portfolio is heavily tilted toward North America at about 89%, with around 10% in developed Asia, largely thanks to Futu. Relative to a global benchmark, that’s an overweight to the US and a big underweight to other regions. This has helped over the past decade as US markets outperformed many others, but it also ties the portfolio closely to one economy, one policy environment, and largely one currency. If US markets lag or face structural headwinds, this concentration could become a drag. A general principle is that including more global exposure can smooth out country‑specific risks, though it may also mean returns look different from a familiar US market index.
Market capitalization
- Mega-cap 41%
- Large-cap 41%
- Mid-cap 16%
- Small-cap 1%
By market cap, the portfolio leans strongly into mega‑caps and large‑caps, each around 41%, with mid‑caps at 16% and small‑caps just 1%. This is quite similar to a mainstream index profile where the biggest companies dominate the weight. Large and mega‑caps tend to be more stable businesses with deeper liquidity and more analyst coverage, which can lower some risks compared with smaller, more volatile stocks. On the downside, it means less exposure to the potentially faster growth (and higher risk) of smaller companies. The tilt toward big names aligns well with global standards and helps keep individual stock risk more manageable, aside from the deliberate single‑stock satellite.

- Top 10 total 41.34%
Looking through the ETF, the top exposures are the big US tech and growth names: NVIDIA, Apple, Microsoft, Amazon, Alphabet, Broadcom, Meta, and Tesla, alongside the separate 10% stake in Futu. These giants appear via the ETF only, so there’s no direct double-counting, but they still cluster risk in a similar growth style. Because only ETF top-10 holdings are captured, actual overlap with other companies is understated. Hidden concentration like this matters because a few large, growthy names can end up driving a big share of returns. The broad ETF does help diversification, but these dominant positions mean performance is still closely tied to how mega-cap growth behaves.
Factors
Factor exposures are estimated using statistical models based on historical data and measure systematic (market-relative) tilts, not absolute portfolio characteristics. Results may vary depending on the analysis period, data availability, and currency of the underlying assets.
Factor exposure looks pretty balanced overall. Factor investing means looking at traits like value, size, momentum, quality, yield, and volatility that research links to returns, like ingredients in a recipe. Here, most factors sit near “neutral,” with no extreme tilts away from the broad market. The one standout is quality at 61%, a mild tilt toward financially strong, profitable, and stable companies. That often supports resilience when markets get choppy, as high‑quality firms may hold up better than weaker peers. This high‑quality lean is a real strength: it suggests the portfolio may behave like a slightly more robust version of the market, without betting heavily on any single factor theme.
Risk contribution
-
Vanguard S&P 500 ETF
Weight: 90.00% 78.5% -
Futu Holdings Ltd
Weight: 10.00% 21.5%
Risk contribution shows how much each holding adds to the portfolio’s overall ups and downs, which can differ from its simple weight. Here, the ETF is 90% of the capital but contributes about 78% of the risk, while Futu is only 10% of the capital yet drives roughly 22% of total risk. That’s because Futu is more volatile, like a loud instrument in an otherwise steady orchestra. This asymmetry is important: even a “small” single‑stock position can meaningfully amplify portfolio swings. A practical takeaway is that anyone uneasy with that extra bumpiness could consider keeping satellite positions small relative to diversified funds so the overall risk better matches their comfort zone.
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 the risk‑return chart, the current portfolio sits right on or very close to the efficient frontier, which is the curve showing the best expected return for each risk level given the existing holdings. The Sharpe ratio, a measure of risk‑adjusted return, is solid at about 0.78, while an optimized mix using the same two holdings could reach around 0.96 by taking on more risk and return. This tells us the present allocation is already efficient for its chosen risk level; there’s no obvious “free lunch” just from reweighting. That’s a reassuring sign: the structure is pulling its weight, and any future tweaks are more about personal comfort than fixing a clear inefficiency.
Dividends
- Vanguard S&P 500 ETF 1.10%
- Weighted yield (per year) 0.99%
The portfolio’s dividend yield is modest at around 1%, reflecting its growth focus. Dividends are the cash payments companies make to shareholders, and they can be a meaningful part of total return over long periods, especially when reinvested. Here, income is clearly not the main story; capital appreciation is. That’s aligned with younger or more growth‑oriented investors who don’t rely on their portfolio for regular cash flow. It also means the portfolio will be more sensitive to price moves rather than income stability. For someone who eventually wants more predictable cash coming out of their investments, shifting toward higher‑yielding assets later in life is a common adjustment.
Ongoing product costs
- Vanguard S&P 500 ETF 0.03%
- Weighted costs total (per year) 0.03%
Costs are a real bright spot. The ETF’s total expense ratio (TER) is a tiny 0.03%, and the single stock carries no ongoing fund fee. TER is the annual management fee fund providers charge, and over decades, even small differences compound into big dollar amounts. Here, the overall fee drag is impressively low and fully in line with best practices for long‑term investing. That means more of the portfolio’s gross return stays in the investor’s pocket. Keeping costs this low is one of the easiest wins in investing, and this setup is doing that exceptionally well. As a foundation, it’s hard to improve much on this fee level.
