Altos Research developed the Market Action Index(TM) for an at-a-glance measurement of market conditions. Primarily, it shows whether it's a Buyer's or Seller's market. The Index is a barometer of real estate supply and demand. A value above 30 indicates demand is relatively robust, which is referred to as a Seller's Market. Below 30 is a Buyer's Market.
Use the Market Action Index as a measurement for the relative health of a market and as an indicator for prices. When markets fall into Buyer's territory prices will likely follow with a downward trend. When markets fall into Seller's territory prices will likely follow with an upward trend.
