Positions

The portfolio is made up entirely of stocks, with a heavy tilt toward a few big individual names plus two broad index ETFs. Around half the money sits in single stocks like GameStop, NVIDIA, and several other high‑beta companies, while the rest is in broad market funds that already hold many of these same giants. This matters because when a small set of positions dominates, overall results can swing wildly based on just a few companies. One way to tighten things up would be to decide which single stocks are truly “core convictions” and let low‑cost broad funds handle the rest, so no single holding can make or break total wealth.

Growth Info

Historically, this mix has produced a huge headline return: a compound annual growth rate (CAGR) above 50%, meaning a hypothetical 10,000 dollars could have grown like a rocket. But that came with a brutal max drawdown above 70%, so that same 10,000 dollars could have dropped to around 2,800 at one point. That kind of ride is far rougher than broad market benchmarks, which usually dip less in crashes. It’s important to remember past numbers describe what did happen, not what must happen again. A useful next step is to ask whether you could stay invested emotionally through another 70% fall, and adjust position sizes to match that reality.

Projection Info

The Monte Carlo analysis uses past returns and volatility to run 1,000 “what if” paths, like rolling dice for the market over and over. The results show a very wide range: in weak scenarios, values drop more than 80%, but in median and higher scenarios, the portfolio can multiply several times over. The simulated annualized return is above 40%, but that assumes the future rhymes with the past, which is never guaranteed. Monte Carlo is a helpful planning tool, not a prediction machine. One practical move is to treat these outputs as guardrails: build a plan for both bad‑case survival and good‑case profit‑taking, instead of assuming the median path will occur.

Asset classes Info

  • Stocks
    100%

Every investable dollar sits in stocks, with no allocation to bonds, cash buffers, or other asset types. Asset classes are like different “engines”: stocks drive growth, while bonds and cash usually cushion falls. Being 100% in stocks means there’s no built‑in shock absorber when markets drop, so volatility will feel amplified compared with a more mixed portfolio. This can be fine for someone with a long horizon and a strong stomach, but it adds pressure in deep downturns. A possible tweak would be to carve out even a modest slice into more defensive assets over time, so future crashes are less likely to force selling at the worst possible moments.

Sectors Info

  • Technology
    33%
  • Consumer Discretionary
    29%
  • Telecommunications
    10%
  • Industrials
    8%
  • Financials
    8%
  • Health Care
    6%
  • Consumer Staples
    4%
  • Energy
    2%
  • Basic Materials
    1%
  • Real Estate
    1%
  • Utilities
    1%

Sector‑wise, the portfolio leans heavily into technology and consumer‑related businesses, with smaller slices in healthcare, financials, and a few others. This tech‑and‑consumer tilt lines up with parts of major benchmarks but is more extreme because of the big single‑stock bets. Sector tilts matter because certain areas boom or struggle based on interest rates, consumer spending, and regulation. For example, growth‑heavy sectors can get hit hard when borrowing costs rise. It’s encouraging that multiple sectors are present, but risk still clusters around a handful of themes. One practical step would be to cap how much any one theme or story stock can represent, to avoid a single narrative dominating outcomes.

Regions Info

  • North America
    100%

Geographically, everything is in North America, effectively the U.S. market. That’s aligned with many U.S.‑based investors and broadly with the global market’s heavy U.S. weight, and it has worked very well over the last decade. The flip side is concentration in one economy, one currency, and one policy environment. If U.S. equities underperform for a stretch while other regions do better, this setup might miss those gains and feel more cyclical. A gradual path could be to decide on a “home bias” level—how U.S.‑centric you want to be—and then slowly build a small percentage into international stocks if broader global exposure fits long‑term goals and comfort.

Market capitalization Info

  • Mega-cap
    50%
  • Mid-cap
    25%
  • Large-cap
    16%
  • Small-cap
    6%
  • Micro-cap
    3%

By market cap, the portfolio leans strongly toward mega and large companies, with some mid, small, and micro‑cap exposure. Market capitalization just means the total value of a company; mega caps are giants, while micro caps are tiny and usually much riskier. This mix is actually quite close to broad benchmarks at the top end, but risk jumps because the smaller caps here are speculative rather than diversified. The large‑cap core is a strength—it tends to be more stable and liquid—while the tiny names add huge swings. One way to keep the upside while calming the ride is to limit how much the most volatile small and micro positions can ever become as a share of total assets.

Redundant positions Info

  • Vanguard Total Stock Market Index Fund ETF Shares
    SPDR S&P 500 ETF Trust
    High correlation

The broad index ETFs in the mix move almost in lockstep, because they track very similar baskets of U.S. companies. Correlation means how often assets move together; when correlation is high, you don’t get much diversification benefit. Holding both major U.S. index ETFs plus overlapping single stocks basically doubles down on the same exposures instead of spreading risk. The good news is the core is aligned with standard benchmarks, which supports long‑run growth. To clean things up, it could help to pick one main broad fund for the “base” and then use spare risk capacity for truly different ideas, rather than owning multiple near‑duplicates that act like one big position.

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.

On a classic Efficient Frontier chart—where “efficiency” means the best return for a given risk using only current ingredients—this portfolio would sit far toward the high‑risk, high‑return corner. Efficient Frontier optimization can sometimes show that slightly different weightings among the existing holdings improve the risk‑return trade‑off without changing what you own. Here, the overlapping index funds and big speculative bets likely pull the portfolio away from that sweet spot. One practical step is to trim redundant holdings and reduce extreme position sizes, then re‑run an optimization using just the cleaned set. That can highlight a mix that keeps the bold upside while cutting some unnecessary turbulence.

Dividends Info

  • Apple Inc 0.40%
  • Avantis® U.S. Small Cap Value ETF 1.60%
  • Costco Wholesale Corp 0.60%
  • Alphabet Inc Class C 0.30%
  • SPDR S&P 500 ETF Trust 1.10%
  • Vanguard Total Stock Market Index Fund ETF Shares 1.10%
  • Weighted yield (per year) 0.42%

Dividend yield across the portfolio is low, under half a percent, because most holdings are growth‑oriented names that reinvest profits instead of paying them out. Dividends are cash payments from companies and can act like a “paycheck” from investments, but they’re not the main driver in high‑growth, speculative approaches. This setup suits a strategy focused on capital appreciation rather than current income, which lines up with the aggressive risk profile. If, in the future, steady cash flow becomes more important—say, for covering living expenses—slowly steering a slice of the portfolio into higher‑yielding, more mature businesses or funds could make the income stream more meaningful without fully changing the growth focus.

Ongoing product costs Info

  • Avantis® U.S. Small Cap Value ETF 0.25%
  • SPDR S&P 500 ETF Trust 0.10%
  • Vanguard Total Stock Market Index Fund ETF Shares 0.03%
  • Weighted costs total (per year) 0.03%

Costs look impressively low, especially on the core index ETF, which keeps more of the return in your pocket over time. The small‑cap value ETF is pricier but still reasonable for an active, factor‑tilted strategy. Expense ratios are like a small leak in a bucket; over many years, even fractions of a percent compound into real money. The good news is the main cost drivers here are in line with best practices, helping long‑term performance. The bigger “cost” in this setup isn’t fees but volatility. A sensible move is to keep favoring low‑fee, broadly diversified vehicles for the base, and treat any higher‑cost or highly speculative positions as clearly defined satellites.
