Covariance measures how two synchronized return series vary together in the scale implied by their return units.
Significado en lenguaje sencillo
Covariance measures how two synchronized return series vary together in the scale implied by their return units.
Por qué es útil
Covariance is useful as descriptive evidence when it is compared on the same definition, source, period, unit and exact listing. It is one input to research, not a verdict.
Dónde aparece en XMarketRadar
Look for Covariance in Portfolio Analytics, Risk Cockpit, holding analysis, performance views and relevant screeners.
Cómo se calcula o se obtiene
Covariance is sourced or derived according to the definition shown above and the screen's disclosed provider, inputs, window and as-of time. Missing required inputs produce an unavailable result.
Entradas, período y unidad
Read the disclosed inputs or source, observation period, bar interval, unit, native currency and scale. A value without its source and as-of context is incomplete; unlike units must not be combined.
Ejemplo práctico
Illustrative only: a user reviews Covariance over a stated 20-bar or FY2026 period, checks the displayed source, unit and as-of date, and keeps an absent field as — rather than guessing 0.
Qué significan alto y bajo
A higher or lower Covariance value is descriptive, not automatically good or bad. Meaning depends on the instrument, comparison period, method and related evidence.
Positivo, negativo y cero real
Positive and negative Covariance values retain the definition shown here. A genuine reported or computed zero is displayed as 0 and is not the same as missing evidence.
Limitaciones y errores comunes
Covariance may differ by provider definition, observation time, instrument and venue. Common mistakes are dropping units or dates, comparing unlike scopes, and treating a missing value as zero.
Diferencias según el mercado
The concept is used across all supported markets, but currency, price scale, session calendar, source field and regulatory definition can differ. XMarketRadar preserves the exact exchange context.
