Historical volatility

ലളിതമായ അർത്ഥം

Historical volatility is annualized population standard deviation of logarithmic observed returns over a stated window and is not implied volatility.

എന്തുകൊണ്ട് ഉപകാരപ്രദം

Historical 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.

Look for Historical volatility in Futures, Option Chain, Options Screener and derivative study tables for a selected underlying and contract.

കണക്കാക്കുന്ന വിധം അല്ലെങ്കിൽ ഉറവിടം

Historical volatility 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.

ഇൻപുട്ടുകൾ, കാലയളവ്, യൂണിറ്റ്

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.

പ്രായോഗിക ഉദാഹരണം

Illustrative only: a user reviews Historical volatility 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.

ഉയർന്നതും താഴ്ന്നതും

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

ധന, ഋണ, യഥാർത്ഥ പൂജ്യം

Positive and negative Historical 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.

എപ്പോൾ ലഭ്യമല്ല

Unavailable (—) means Historical volatility 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.

പരിമിതികളും സാധാരണ പിഴവുകളും

Historical volatility 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.
