What you get

A portfolio memo, not just charts

PortfoMemo runs a structural diagnostic on your portfolio: concentration first, risk second, narrative last. Instead of generic commentary, you get a focused review of what your portfolio is optimized for, where it is fragile, and what drives its outcomes.

Example analysis

See what your portfolio actually looks like

Most portfolios feel diversified until you look at what really drives returns. PortfoMemo turns a list of holdings into a structured diagnosis.

Portfolio Verdict

Tech-heavy with a single dominant position — 28 holdings provide diversification in count but not in exposure. Returns are driven primarily by large-cap tech momentum.

Construction Score

58/100

Risk Posture

Aggressive

Portfolio Type

Diversified but Thematic

Structural Observations

  • Sector dependence — Over 60% of portfolio weight is concentrated in technology, creating a single-sector outcome profile.
  • Correlated upside — Top holdings share exposure to AI infrastructure spending and large-cap tech beta.
  • Limited downside offset — Defensive and value allocations are too small to meaningfully reduce drawdowns.

Favorable

Quality Score

82 / 100

Sector

Technology — Semiconductors

Volatility

High

  • Portfolio role — Growth amplifier and AI infrastructure play. Increases tech concentration and portfolio volatility.
  • Hidden overlap — Already held in VOO (~1.5%) and QQQ (~8%). Adding a direct position compounds exposure.
