What's worth noticing
in your holdings.

Holdings-relevant depth and breadth — with you through the cycle, as lasting judgment compounds.

Portfonia is holdings intelligence built to last through market cycles. We keep watching the news, the macro, and company developments, and map them systematically onto every position you actually hold — depth and breadth that stay close to what you care about. Cycles rise and fall; the judgment worth keeping for years needs information you can trust for years. That is why we exist.

Macro signals

Markets repriced the policy path after the latest FOMC minutes showed a split committee. The transmission into this portfolio runs through the equity-duration channel: long-duration growth names (TSMC, Microsoft, Alphabet) and the broad ETFs are mechanically sensitive to shifts in rate expectations embedded in the yield curve. No price anomaly was triggered in this window to confirm a repricing in any specific holding, so this direction stands as structural exposure to monitor rather than an observed event. [Probable]

Holding analysis

TSMC — 20.9% of the portfolio, the single largest position

TSMC stands out this period not for a company-specific event but for its disproportionate weight and its exposure to several macro themes at once. The monetary-policy theme reaches it through the equity-duration channel: as a pure-play foundry, its forward multiples already embed years of capex-driven growth from advanced nodes, so its valuation is mechanically sensitive to rate expectations. The AI-infrastructure demand narrative underpinning the position is unchanged; what is new is a less predictable policy path adding an intermittent source of valuation volatility. The causal link between holding TSMC and the monetary-policy signal runs through that well-documented duration mechanism [Probable] — though no anomaly was observed in this window to confirm the market actually traded on it.

Risk radar

The top three holdings together account for 50.0% of portfolio value — at the 50% watch threshold. The largest single asset-class bucket (stocks) sits at 48.1%, just below it. Single-position concentration is dominated by TSMC at 20.9%; the two broad ETF positions diversify within US equities while raising correlation to US monetary-policy developments.

Get started

For investors who stay through the cycle

Portfonia is holdings intelligence that stays with investors through the cycle. We believe that decisions of real quality rest on a deep reading of trends, cycles, and fundamentals — a reading that takes time, and that needs information closely tied to what you hold, delivered continuously and reliably.

Our work is to take what is scattered across news, macro events, and company developments, and map it back, systematically, onto every position you hold. That is how you get depth and breadth that actually fit the names you follow — so you can see where an asset sits, what is changing around it, and which signals are worth a closer look. Judgment stays yours. We make sure that judgment sits on solid information.

Market cycles rise and fall. What Portfonia stays with is the decision that spans a cycle and still holds up when time has had its say.

Deliberately out of scope

Portfonia is an intelligence service, not an advisory one. The boundary is enforced at the template and prompt layer — not left to the model's judgment.

  • No buy / sell / hold / reduce / increase / target-price language. Ever.
  • No trade execution, no broker integrations beyond ingest-only.
  • No tax or capital-gains computation, no P&L from trade history.
  • No options, futures, or derivatives.
  • No threshold price alerts — every broker app already does that.
  • No social or sharing features — holdings are sensitive data.

Frequently asked

Before you ask
Is this investment advice?
No. Portfonia is an intelligence service — it tells you what happened and why it might matter, helping you make timely, well-informed decisions. See “Deliberately out of scope” above.
Is my holdings data safe?
Yes — your holdings are strongly encrypted at rest (field-level encryption in our database). On top of that, AI calls run with training-data collection denied by default, and each call only sees the data a given report actually needs — never the whole portfolio wholesale.
Which markets and holdings does it support?
US equities, HK equities, A-shares, Chinese public funds, cash, and FX today. More coverage is planned.
What does it cost?
Portfonia is in a multi-user closed beta right now — content and features may differ by subscription tier when plans are announced.
