Metric Dictionary

Public performance numbers should be traceable. This page defines the major metrics shown on Starting Index, where they come from, and whether they describe live results, reconstructed profile context, or research backtests.

Live platform record

Live Platform Return

Formula: Ending platform value divided by starting platform value, minus 1.
Source: published/performance/daily_close_snapshot.json, reconciled to published/performance/daily_returns.csv
Date Range: Platform live record since inception.
Update Cadence: Updated after the end-of-day performance artifact is published.

Benchmark comparison

SPY Return

Formula: Ending SPY benchmark value divided by starting SPY benchmark value, minus 1.
Source: published/performance/daily_close_snapshot.json, reconciled to published/performance/daily_returns.csv
Date Range: Same dates as the platform, profile, or research value being shown.
Update Cadence: Updated with the same artifact as the Live Platform Record.
Important Note: SPY price return, dividends excluded from published benchmark artifact. The benchmark basis is artifact-labeled and must match the paired strategy window.

Derived comparison

Excess Return

Formula: Model or platform return minus SPY return over the same date range.
Source: Calculated from the paired strategy and benchmark values in the public performance artifacts.
Date Range: Always the same range as the paired strategy and benchmark values.
Update Cadence: Updated whenever the underlying return values update.
Important Note: Excess return is only meaningful when both values use the same date range and benchmark basis.

Live partial-period metric

MTD

Formula: Current value divided by the prior close before the first trading day of the current month, minus 1.
Source: published/performance/daily_returns.csv and published/performance/monthly_returns.csv
Date Range: Current month through the latest available close.
Update Cadence: Updated after each end-of-day artifact during the month.

Live rolling metric

30D / 90D

Formula: Current value divided by the latest available value before the rolling cutoff date, minus 1.
Source: published/performance/daily_returns.csv
Date Range: Rolling 30 or 90 calendar days through the latest available close.
Update Cadence: Updated after each end-of-day artifact.

Live calendar-period metric

YTD

Formula: Current value divided by the prior close before January 1 of the current year, minus 1.
Source: published/performance/daily_returns.csv
Date Range: Calendar year through the latest available close.
Update Cadence: Updated after each end-of-day artifact.

Live platform record

Since Inception

Formula: Current value divided by the first published live value, minus 1.
Source: published/performance/daily_returns.csv
Date Range: First Live Platform Record date through the latest available close.
Update Cadence: Updated after each end-of-day artifact.

Monthly live/platform metric

Monthly Pulse

Formula: Monthly strategy return, benchmark return, and excess return from the monthly performance artifact.
Source: published/performance/monthly_returns.csv
Date Range: Completed months, plus the current month-to-date row when the month is still open.
Update Cadence: Updated monthly and during the current month when end-of-day artifacts publish.

Current model context

Model Preview

Formula: Published basket constituents ranked by recent return over the current publication window.
Source: published/performance/daily_close_snapshot.json leaders, falling back to published/current_leaders.csv
Date Range: Current publication window through the latest available close.
Update Cadence: Updated after each end-of-day artifact.

Research backtest

Backtest CAGR

Formula: Annualized compound growth rate over the research equity curve.
Source: Research run summaries and validation artifacts under the published research artifacts.
Date Range: Historical research window shown on the Evidence page.
Update Cadence: Updated only when research artifacts are regenerated and republished.
