Valuations are forward looking of course so it doesn't necessarily say anything about future valuations for Norbord; however, have you been down to Home Depot lately?  I bought some tongue-and-groove spruce plywood and it cost $10 more per sheet.  That's like a sudden 30% jump in price!  Very bullish for quarterly sales volumes of the cheaper OSB alternative made by Norbord I would suspect.  P.S. I'm a Norbord shareholder but ironically I dislike OSB and wouldn't choose to build with it myself.  It's just been a compelling investment story over the last few years.
