Alpha
Alpha is a model-dependent return component not explained by the selected benchmark and assumptions.
Plain-language meaning
Alpha is a model-dependent return component not explained by the selected benchmark and assumptions.
Why it is useful
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.
Where it appears in XMarketRadar
Look for Alpha in Portfolio Analytics, Risk Cockpit, holding analysis, performance views and relevant screeners.
How it is calculated or sourced
Estimate the intercept or unexplained return from the disclosed benchmark model, frequency and risk-free-rate convention. It is model-dependent.
Inputs, period and unit
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.
Worked example
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.
What high and low mean
A higher or lower Alpha value is descriptive, not automatically good or bad. Meaning depends on the instrument, comparison period, method and related evidence.
Positive, negative and genuine zero
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.
Limitations and common mistakes
Historical estimates are sensitive to sample length, frequency, missing sessions, benchmark, currency and outliers. They can change and do not predict future outcomes.
Market-specific differences
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.
