What Is WD-40's Investment Narrative?

To own WD-40, you really have to believe in the staying power of a focused niche brand that converts its household name into steady, if unspectacular, growth and consistent dividends. The story today revolves around whether recent pricing, volume trends and margins can support the current premium valuation, especially after a strong run in the share price and only modest earnings growth expectations. Short term, the key catalysts remain execution on international expansion, protecting margins in the face of input cost shifts, and disciplined capital returns through dividends and buybacks. Director David Pendarvis’s latest share purchase, reinforcing a year of insider buying with no sales, adds a supportive signal but does not fundamentally change those drivers. It mainly underpins confidence at a time when a high price-to-earnings multiple heightens sensitivity to any operational wobble.

However, investors should be aware that paying a high multiple leaves little room for disappointment. WD-40's shares are on the way up, but they could be overextended by 18%. Uncover the fair value now.
