This paper investigates the real impact of sector performance on the overall stock market and the possibility that the primary culprit of negative or positive performance isn’t necessarily the one that significantly drives overall market performance. The study compares average gain or loss by sector with regression analysis to determine if the largest gainer or loser is also reflected in regression analysis after beta calculation. The results show that there is very limited correlation between the two measures suggesting that major volatility in one sector doesn’t necessarily have the greatest impact on total market movement.
