Alpha

எளிய மொழி விளக்கம்

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

இது ஏன் பயனுள்ளது

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.

XMarketRadar-ல் எங்கு தோன்றும்

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

எப்படி கணக்கிடப்படுகிறது அல்லது பெறப்படுகிறது

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

உள்ளீடுகள், காலம் மற்றும் அலகு

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.

நடைமுறை உதாரணம்

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.

உயர்வு மற்றும் தாழ்வு பொருள்

A higher or lower Alpha value is descriptive, not automatically good or bad. Meaning depends on the instrument, comparison period, method and related evidence.

நேர், எதிர் மற்றும் உண்மையான பூஜ்ஜியம்

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.

எப்போது கிடைக்காது

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.

வரம்புகள் மற்றும் பொதுவான தவறுகள்

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

சந்தை சார்ந்த வேறுபாடுகள்

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.
