OC needs new construction to improve. New home sales need to get over 1 million units to get them moving in the right direction. Because the number of builders have decreased by 50%, builders only need around 600,000 units a year.
Most of these suppliers have taken on huge debt or issued more stock to get them through this housing downturn. So these companies need to make more money than they did during the boom to pay for the debt. To make it more difficult, most of these suppliers have the same competitors they had during the boom. USG and National are still out there competing for the limited amount of business.
I think the market just got out ahead of themselves on the suppliers. Most of them are the analyst that want to play the building sector without going into the home builders.
