Are you sure this Graph is timber prices rather than share prices or some other index. The source is Nasdaq, I quote “Both the Dow and the Nasdaq, then, are terms that refer to an index, or an average of a great many numbers derived from the price movements of certain stocks“.
It’s the commodity price of timber. Like oil or copper. It is the US dollar price per 1,000 board feet.
