K–W: Kruskal–Wallis test (p value is in parenthesis). Ratio is the division of average return between two periods. For example, the ratio after column “2020” divides the average return for the year 2020 by the daily average return of the period 2012–2019. The columns “Dec/2011”, “2012–2019” and “2020” include the daily average return in each period
