Activity picked up in the lumber market yesterday as traders, returning from the long holiday weekend, made their impact. There was also more lumber available from the eastern mills enabling buyers to put together back-to-back business with them. Prices moved higher as a result. It was a busier market than many were expecting, emphasizing a stronger undercurrent of demand in the market. The continuing outflow of product through various entities has kept pressure on replenishing inventories more often, despite many not wanting to.
