Volatility
Volatility measures variation in returns over a stated frequency and window, often annualised.
Plain-language meaning
Volatility measures variation in returns over a stated frequency and window, often annualised.
Why it is useful
Volatility 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 Volatility in Portfolio Analytics, Risk Cockpit, holding analysis, performance views and relevant screeners.
How it is calculated or sourced
Calculate dispersion of periodic returns over the selected window. Annualised volatility scales by the square root of periods per year only when that convention is stated.
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: If daily return standard deviation is 1%, a common annualized estimate is about 15.9% using 1%×√252; this assumes the stated daily convention.
What high and low mean
A higher or lower Volatility 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 Volatility 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.
