Personal investment portfolio · 30 Jun → 4 Sep 2026
A small book.
A small book.
A real process.
Built from scratch on 30 June 2026. The point is not to manufacture a track record; it is to make the thinking visible — position sizing, risk, research, and the discipline to record the outcome.

How to read this book. I am deliberately showing a short history rather than dressing it up as performance evidence. The capital is small because it is personal. What matters here is the repeatable process: why a position exists, how large it is, what changed, and what happened next.

Statistical caveat: with 47 trading days of history, all statistics are directional and should not be extrapolated into an annual return with any confidence. Sector-level detail vs matched ETF benchmarks (not just broad indices) is in Attribution below.

"Return" is simple return on cost basis (unrealised P&L ÷ avg cost), distinct from the TWR figure used in Overview/Performance. Weight is % of total account NAV including cash.
04 / Risk
The risk-adjusted picture.
All ratios below use 47 completed daily closes through 4 Sep 2026. Samples under 30 are directional, not statistically reliable. Risk-free rate assumed 3.90% p.a. (current US 3m T-bill), daily 0.0155%.

Risk-adjusted ratios vs benchmarks
| Metric | Portfolio | SPY | QQQ | Read |
|---|---|---|---|---|
| Sharpe (annualised) | 1.99 | 1.19 | −0.71 | Portfolio still leads on risk-adjusted return |
| Sortino (annualised) | 3.29 | 1.95 | −1.07 | Same story on downside-only risk |
| Annualised volatility | 15.3% | 11.1% | 20.7% | Portfolio sits between the two indices |
QQQ now shows a negative Sharpe/Sortino over these 47 trading days since it has fallen since inception (−2.37%), well short of the ~3.90% annualised risk-free rate used here. SPY clears that hurdle (+3.14%), though still well behind the portfolio.
Position-level risk flags — based on real weights & live P&L
| Position | Flag | Detail | Severity |
|---|---|---|---|
| NVDA | New largest position | 16.74% of NAV — overtook AVGO as the largest position in the book on its rally, still comfortably under the 20% single-name guideline; up 15.53% since entry | Monitor |
| LHX | Largest dollar & % drawdown | −11.23% / −$83.17 unrealised — remains both the largest dollar loss and the largest percentage decliner in the book, and the gap has widened | Watch |
| Cash | Fully deployed | 0.5% cash — essentially no dry powder; next contribution needed before any new buy | Monitor |
Position-level flags reflect real weight and P&L concentration, not fundamental-analysis scores (e.g. Piotroski, Altman Z) — those require deeper financial-statement research.
05 / Attribution
Where the alpha came from.
Each sleeve is appraised against its actual sector ETF, not just the broad market — isolating whether stock selection and entry timing added value.
Total active return vs QQQ (TWR basis)+8.77pp
Sleeve return vs matched sector benchmark
