G4S PlcのBetaは1.30です。
BETAは、株式が市場全体よりも多かれ少なかれ揮発性であるかどうかを示します。 1未満のベータは株式が市場よりも揮発性が低いことを示し、1より大きいベータは株式がより揮発性であることを示します。ボラティリティは、平均値周辺の価格の変動として測定されます。
Beta is a measure of the risk arising from exposure to general market movements as opposed to idiosyncratic factors. The market portfolio of all investable assets has a beta of exactly 1. A beta below 1 can indicate either an investment with lower volatility than the market, or a volatile investment whose price movements are not highly correlated with the market. A beta greater than one generally means that the asset both is volatile and tends to move up and down with the market. Beta is important because it measures the risk of an investment that cannot be reduced by diversification. It does not measure the risk of an investment held on a stand-alone basis, but the amount of risk the investment adds to an already-diversified portfolio. In the capital asset pricing model, beta risk is the only kind of risk for which investors should receive an expected return higher than the risk-free rate of interest.
