Alpha

Significado en lenguaje sencillo

Alpha is a model-dependent return component not explained by the selected benchmark and assumptions.

Por qué es útil

Alpha 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 Alpha in Portfolio Analytics, Risk Cockpit, holding analysis, performance views and relevant screeners.

Cómo se calcula o se obtiene

Estimate the intercept or unexplained return from the disclosed benchmark model, frequency and risk-free-rate convention. It is model-dependent.

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 fitted annualized alpha of +2% means the chosen model left 2% unexplained return in that sample; another benchmark or period may remove or reverse it.

Qué significan alto y bajo

A higher or lower Alpha 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 Alpha values retain the definition shown here. A genuine reported or computed zero is displayed as 0 and is not the same as missing evidence.

Cuándo no está disponible

Unavailable (—) means Alpha is absent, unsupported, stale under the screen's rules or not computable from verified inputs. It must never be converted to zero or a neutral signal.

Limitaciones y errores comunes

Historical estimates are sensitive to sample length, frequency, missing sessions, benchmark, currency and outliers. They can change and do not predict future outcomes.

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.
