“…In no case did either a simple P/S or P/E portfolio provide the highest return of the six strategies investigated. Taken together, these results are consistent with previous studies that found the P/S ratio was a better selection criterion than the P/E ratio (e.g., Nathan et al, 2001;Vruwink et al, 2007;Barbee et al, 2008), and inconsistent with previous studies that found the opposite (e.g., Senchak & Martin, 1987;Chou & Liao, 1996). However, our results strongly suggest that reliance upon either single investment criterion is no guarantee of superior investment performance.…”
