W.W. Grainger, Inc.
Thesis
Grainger is a leading distributor of maintenance, repair, and operations supplies with significant market share growth potential, as it currently holds less than 5% of a $140 billion market. The company has a strong customer value proposition that generates repeat purchases.
Did it work?
The long thesis on Grainger has played out well: the stock returned +36.7% over 28 months (~15% annualized), a strong result for a long position with no stated price target or horizon. The thesis's core dynamics — share gains in a fragmented $140B MRO market and a repeat-purchase value proposition — are consistent with the sustained positive performance, and nothing in the interim contradicted the thesis. Given the substantial elapsed time and clearly favorable return in the stated direction, the pitch can be judged a success.
