Weyerhaeuser (NYSE:WY) is a good example of a stock where it can be challenging to nail down the fair value. Cash flow doesn't necessarily account for the underlying value of the timberland and can miss the cyclicality of the housing cycles, but sum-of-the-parts net asset valuations can require a lot of work to find reasonable inputs/comparables for timberland valuation. Be that as it may, I think Weyerhaeuser offers decent value today on the strength of its extensive timberland assets and the improvements the company has made not only toward streamlining and focusing the business, but also in improving operating margins in the manufacturing operations.
It's been a while since I've updated my coverage on this company, but I think $30 to $35 a share is a reasonable (albeit wide) range for Weyerhaeuser shares, with $35 as the "sweet spot" on the basis of my sum-of-the-parts valuation. A trade war with Canada over lumber is a looming issue, but one that shouldn't hurt Weyerhaeuser, and I like the company's leverage to increasing housing activity albeit with some caution on what would be a potential oversupply of lumber into the market in the coming years.
