Slight Seller's Advantage
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.
