Market Narrative
Market conditions have been consistently cooling in the past several weeks. Because we’re still in the Seller’s zone, prices have not yet begun to drop. It may take a few more weeks of slack demand for prices to reflect and begin to fall. Expect prices to fall if the index persistently falls to the Buyer’s zone.
