Note(s): This table reports the mean of the coefficients of two performance measures for sector funds and sector ETFs for the pre-COVID-19 period (2015–2019) : (1) the alphas estimated from the six-factor model of Fama and French (2018) and their corresponding p-values, and (2) the information ratio (IR) measured by using the alpha for the numerator and the standard deviation of the regression-adjusted error for the denominator. Monthly returns on sector funds and sector ETFs are gathered from the Morningstar Direct Database from 2015 to 2023. Active sector funds are split into two groups based on whether their Morningstar sustainability score is below (Low) or above (High) the PCSS of their corresponding sector ETF. The two-sample t-test is used to compare the difference between the two means (high versus low) to zero (Difference)
