WD-40: A Well-Oiled Machine With Limited Upside

WD-40 earns a Superscore of 79 out of 100 for its strong operational efficiency, robust margins (56.6%), and disciplined focus on high-margin maintenance products. However, the stock trades at a stretched valuation (P/E of 37.7) with limited growth prospects, structural headwinds from commoditization and the EV transition, and is expected to underperform the S&P 500 over the next five years.
