Costco remains trading at a significant premium to the rest of the US retail segment. The P/E ratio of 54.4x remains more than 2 times the value for the sector as a whole. On a P/BV and P/S ratio basis, the company also significantly outperforms its segment.
This situation has been going on for a long time, and looking at historical forward P/E ratios, Costco's ratio has exceeded the sector by an average of 1.78x and the entire S&P 500 index by 1.86x. Even with the trend of strong premium to index, current Costco values implies strong overvaluation.

Although since the beginning of 2018 it has presented a return of 365% (compared to the sector's return of 114%) it is worth remembering that trading in the area of such high ratios exposes the company to potentially greater volatility in the event of disappointing post-performance data.
