QQQM - US46138G6492 40.00%
This portfolio is extremely simple: two US stock ETFs and nothing else, with 60% in a broad US large‑cap fund and 40% in a NASDAQ 100 tracker. That means every dollar is tied to equities, with a sizable tilt toward growth‑oriented companies. Simplicity like this is powerful because it’s easy to understand and maintain, but it also means you’re very dependent on one asset class and one country. For a growth‑oriented investor, this structure can work well, especially if the time horizon is long. Anyone using a setup like this just needs to be comfortable with big swings and the fact that there’s almost no built‑in cushioning from bonds or cash.
Growth
Over the period from late 2020 to early 2026, $1,000 grew to about $2,041, giving a compound annual growth rate (CAGR) of 13.98%. CAGR is basically your average “speed” per year, smoothing out the bumps. That slightly beats both the US market and the global market, which is a solid result. The trade‑off is a max drawdown of -28.5%, meaning the portfolio once fell almost 30% from peak to trough and took over a year to recover. This level of drop is typical for growth‑heavy stocks. The performance shows that taking extra risk has, so far, been rewarded, but it came with real psychological tests along the way.
Projection
The Monte Carlo simulation takes past return and volatility patterns and runs 1,000 “what if” scenarios for the next 15 years. Think of it as rolling the dice on many possible market paths, not just repeating history. The median outcome of about $2,823 from $1,000 implies decent growth, but the range is wide: from around $960 (basically no progress) at the pessimistic end to over $8,000 in very strong markets. The expected annualized return across simulations is 8.34%, but none of these numbers are guarantees. They just frame the odds, showing that a growth‑tilted stock portfolio can be rewarding over time but is far from a straight line.
Asset classes
- Stocks 100%
All of the money here is in stocks, with 0% in bonds, cash, or alternatives. That 100% equity stance explains both the strong long‑term return potential and the sizable drawdowns you’ve seen historically. Different asset classes tend to respond differently to economic shocks, so mixing them usually reduces the depth of downturns. Here, the only buffer in a bad market is your own ability to stay invested. For investors with long horizons and steady outside income, an all‑equity mix can be appropriate. For anyone with shorter timelines or lower risk tolerance, blending in other asset classes is often how people smooth the ride without trying to time the market.
Sectors
- Technology 40%
- Telecommunications 13%
- Consumer Discretionary 11%
- Health Care 8%
- Financials 7%
- Consumer Staples 7%
- Industrials 7%
- Energy 2%
- Utilities 2%
- Basic Materials 2%
- Real Estate 1%
Sector exposure is skewed toward technology at about 40%, with meaningful slices in telecommunications and consumer areas, and smaller positions in more defensive segments like utilities and consumer staples. Relative to common broad‑market mixes, that tech share is high, largely driven by the NASDAQ 100 allocation and the dominance of big tech in US indices. Tech‑heavy portfolios tend to shine when growth is rewarded and interest rates are stable or falling, but they can feel sharper drawdowns when rates rise or investors rotate into more value‑oriented businesses. The upside is strong participation in innovation; the downside is a portfolio that will likely be more cyclical and volatile around macro news than a more sector‑balanced lineup.
Regions
- North America 99%
- Europe Developed 1%
Geographically, the portfolio is almost entirely in North America, at 99%, with only a token 1% in developed Europe. That’s a classic “home bias” setup for a US‑focused investor and has worked nicely over the last decade, since US stocks have outpaced many other regions. The trade‑off is that results are tightly tied to the US economy, policy, and currency. If other regions lead for an extended period, a portfolio like this may lag global benchmarks simply because it has almost no exposure there. Aligning closely with the US market is a valid choice, but it’s worth being aware that global stock markets are broader than what’s represented here.
Market capitalization
- Mega-cap 48%
- Large-cap 35%
- Mid-cap 15%
- Small-cap 1%
Market cap exposure is heavily tilted toward mega‑cap and large‑cap companies, which jointly make up over 80% of the portfolio. Only about 16% sits in mid and small caps. Large, established firms often have more stable earnings, deep moats, and better access to capital, which can dampen some volatility compared to a small‑cap‑heavy portfolio. At the same time, smaller companies sometimes drive outsized returns in certain cycles because they have more room to grow. Here, the focus on big names means the portfolio should broadly track the behavior of major US indices, especially when mega‑caps are leading markets, but it will capture less of the “smaller company” risk and opportunity.

- Top 10 total 39.45%
Looking through the top ETF holdings, the portfolio leans heavily on a handful of giant tech and tech‑adjacent names: NVIDIA, Apple, Microsoft, Amazon, Alphabet, Meta, Broadcom, and Tesla together already make up a big chunk of the visible exposure. Many of these appear in both ETFs, which creates hidden concentration even though you only see two tickers. Because only top‑10 ETF holdings are captured, the true overlap is probably a bit higher than reported. This concentration can be great when those leaders are winning but can amplify pain if they all stumble at once. The key takeaway is that ticker count is not the same as underlying company diversification here.
Factors
Factor exposure looks quite balanced overall, with most characteristics around neutral. The only mild tilts are low scores in value and size, which together signal a bias toward larger, growthier companies rather than cheaper, smaller ones. Factors are like underlying “ingredients” that drive returns — value, size, momentum, quality, low volatility, and yield. A mild tilt away from value and size means the portfolio may do especially well when growth and mega‑caps are in favor, but could lag in phases when cheap, smaller stocks outperform. The good news is that without extreme tilts, the portfolio behaves broadly like the overall market, just with a growth‑leaning flavor.
Risk contribution
-
Vanguard S&P 500 ETF
Weight: 60.00% 53.1% -
Invesco NASDAQ 100 ETF
Weight: 40.00% 47.0%
Risk contribution shows how much each position drives the portfolio’s ups and downs, which can differ from simple weights. Here, the S&P 500 ETF is 60% of the assets but contributes about 53% of the risk, so it’s slightly less volatile than its size suggests. The NASDAQ 100 ETF is 40% by weight but nearly 47% of the risk, meaning it punches above its weight in terms of volatility. That’s common for a tech‑heavy growth fund. Together, they account for 100% of the risk, which is expected with just two holdings. Anyone wanting to dial down overall swings would usually adjust the higher risk‑per‑weight position or mix in lower‑volatility assets.
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 the current mix sitting right on or very close to the efficient frontier. The efficient frontier is the curve of best possible return for each level of risk using only your existing ingredients. The Sharpe ratio, which measures return per unit of risk above a risk‑free rate, is 0.59 for the current mix versus 0.8 for the optimal/minimum‑variance combination listed. Since those optimal and minimum‑variance points are the same here, it suggests that adjusting weights slightly could improve risk‑adjusted returns without changing holdings, but the current allocation is already quite efficient. Structurally, the portfolio is making good use of its chosen building blocks.
Dividends
- Invesco NASDAQ 100 ETF 0.50%
- Vanguard S&P 500 ETF 1.20%
- Weighted yield (per year) 0.92%
The overall dividend yield is around 0.92%, with the broad S&P 500 ETF yielding about 1.2% and the NASDAQ 100 closer to 0.5%. That’s on the low side compared with many income‑oriented portfolios, but very typical for a growth‑focused US equity mix. Dividends can be a nice steady component of total return, especially for people drawing income, but capital gains are clearly the main driver here. For an accumulator with a long horizon, a lower yield isn’t inherently a problem — many fast‑growing companies choose to reinvest rather than pay out cash. The key is just not to expect meaningful cash flow from this portfolio alone in the near term.
Ongoing product costs
- Invesco NASDAQ 100 ETF 0.15%
- Vanguard S&P 500 ETF 0.03%
- Weighted costs total (per year) 0.08%
The total ongoing cost (TER) is impressively low at about 0.08% per year across the two ETFs, with 0.03% on the S&P 500 tracker and 0.15% on the NASDAQ 100 fund. TER, or Total Expense Ratio, is like a yearly subscription fee expressed as a percentage of your investment. Keeping this number low is one of the few things investors can fully control, and over decades, even tiny differences compound into real money. Relative to typical active funds or pricier ETFs, this cost level is excellent and very much aligned with best practices for long‑term investing. The structure is doing what it should: capturing market returns without taking too much off the top.
