What data the evaluator uses.

Your portfolio analysis combines the holdings you enter with available instrument profiles and market evidence. Coverage and freshness vary, so checking the data gaps is part of understanding the result.

The holdings you enter

For the free browser check, enter ticker symbols and current market values, plus optional cash and a low, medium or high risk setting. Use the same currency throughout. PORTIQA does not connect to your broker, so it cannot correct an outdated value or add a holding you leave out.

Running an analysis does not automatically save your holdings. You can choose to save them with a free account and reopen them for a later check. Saving retains the inputs, not a score history or a live broker balance. See the Privacy Policy for data handling.

Security master and classifications

The reference universe maps tickers and exchanges to supported instruments and related profile fields. These may include exchange, sector, company or fund classification, close price, beta, grade, dividend, signal, and trend fields where available. Coverage varies by instrument and market.

A recognised ticker does not mean every analysis field is available. Check missing-ticker and coverage information in your result, especially for less widely covered instruments.

Derived factor and market context

The evaluator can use time-windowed ticker-to-factor correlations and betas, factor-regime snapshots, broad market-regime snapshots, and sector-regime snapshots. The implementation uses multiple horizons for factor evidence and attaches confidence or stability measures where available. These are derived indicators, not statements about future performance.

Freshness

Context tables are read from their latest available snapshot. Different data categories can have different as-of dates because classifications change less often than prices or regime measures. An evaluation should therefore be treated as current to the underlying snapshots, not necessarily to the exact request second.

The evaluation time records when the analysis ran; it is not a promise that every source field was refreshed at that moment. A later evaluation can change even if you enter the same holdings. Update the market values you enter when you want to check your portfolio's current allocation.

Coverage and gap reporting

The response exposes coverage for beta, grade, dividend, trend, and macro context. Diagnostics also report classification quality, factor-evidence quality, low-confidence or missing weight, and a list of data gaps. An unresolved ticker is returned in missing_tickers; PORTIQA does not manufacture a profile for it.

Funds and ETF overlap

Funds are treated as individual positions. PORTIQA does not retrieve their underlying holdings, calculate overlap between ETFs or reconstruct their underlying sector exposure. A fund's profile describes the fund itself; it does not stand in for all the securities inside it. The methodology explains the resulting limits and display safeguards.

Source transparency

This public page describes data categories and transformations. It does not provide a complete list of upstream vendors or an independently audited coverage inventory. For a specific data-source or coverage question, contact hello@portiqa.com with the instrument and field you want to check.

Known limitations

• Ticker reuse, corporate actions, exchange suffixes, and stale classifications can cause resolution errors.
• Coverage is not uniform across all claimed assets and markets.
• Historical relationships can weaken or reverse during regime changes.
• Missing fields lower confidence; they must not be interpreted as neutral evidence.

For API integrations

API usage logs contain the key identifier, endpoint, timestamp and HTTP status for billing, abuse prevention and support; they do not retain request or response payload bodies. Integrations should preserve the returned engine version and coverage diagnostics when displaying a result. See the API documentation for field definitions.
