This chart shows the price of buying lumber, not the appreciation or depreciation of companies that deal in lumber. (Weyerhaeuser, Boise Cascade). Need to look at actual timber product companies or reference home builder stocks.
What that chart actually shows is the increasing price of lumber could be contributing to ECO price per share being lower. The more expensive the lumber is, perhaps the less likely the purchaser is going to be to pay for the additional cost of having a product like Red Shield added to it.
Is the suggestion that since the price of lumber futures have gone up then the price of ECO shares should have gone up?
