Beta

Business Term of the Day

Definition

Beta is a measure of a stock’s volatility relative to its market.

Example sentence

Despite ACME’s low beta, the recent drop in its share price coincided with the market slump and therefore many investors lost money.

Comment

A beta is used for assessing the market risk of a given stock. If the beta is equal to one, the asset’s price moves up and down in step with the market cycle (as is the case, for example, with cyclical stocks). If it is greater than one, the asset is more volatile than the market. If it is close to zero, the asset has low correlation to the market cycle and may be considered a defensive stock. An asset with a negative beta would be countercyclical, i.e. its price would increase when the market goes down and decrease when the market goes up, although such assets are relatively rare.

Definice

Beta je měřítko volatility akcie oproti jejímu trhu.

Příklad použití ve větě

Navzdory nízké betě společnosti ACME se nedávný pokles ceny akcií kryl s tržním propadem, a mnoho investorů proto přišlo o peníze.

Poznámka

Beta se používá k posouzení tržního rizika dané akcie. Pokud je beta rovna nule, cena aktiva se pohybuje nahoru a dolů v souladu s tržním cyklem (jak je tomu například u cyklických akcií). Pokud je vyšší než jedna, je aktivum volatilnější než trh. Pokud je blízká nule, má aktivum nízkou korelaci k tržnímu cyklu a může být považováno za defenzivní akcii. Aktivum se zápornou betou by bylo proticyklické, tj. jeho cena by se zvyšovala, když jde trh dolů, a snižovala, když jde trh nahoru, ale taková aktiva jsou relativně vzácná.
