BLDR position long Ed Bosek

Thesis

The U.S. housing market has disappointed investors, but signs of recovery are emerging, including improved labor markets and accessible financing. Builders FirstSource, as a lumber distributor, is well-positioned due to industry consolidation and cost-cutting measures, making it an attractive investment opportunity.

Did it work?

worked confidence: high

The long thesis on Builders FirstSource played out emphatically, with the stock returning +464.3% since the pitch. This magnitude of gain decisively confirms the core thesis dynamics — a housing recovery, benefits from industry consolidation, and cost-cutting driving outsized earnings growth. Even without knowing the exact time elapsed, a return of this size is far beyond normal noise and validates the bullish call regardless of the stated horizon.
