According to Altos Research the MAI measures the balance between supply and demand as a function of the current rate of sales versus current inventory. An MAI value greater than 30 typically signals a “Seller's Market” in which the demand is high enough to quickly absorb available supply, while an MAI value below 30 signals a "Buyer's Market" in which the available supply is sufficient to satisfy demand, as measured by the current sales rate, for several months.
