The Calculation: To quantify the data, I measured each of those four statistics (YTD return, number of up days, standarddeviation, and maximum drawdown) against all other stocks and gave them a score from zero to 100.
Indulge me in a quick stat geek moment: the basic standarddeviation formula marks greatness across eras by showing the degree to which you stand out from the crowd in a given year (a team with fewer patsies to beat up on will score higher than a team than a team feasting on more patsies, records being equal).
