NAHB/Wells Fargo Housing Market Index (HMI) is based on a monthly survey of home builders. They are asked to rate current sales of single-family homes and sales expectations for the next six months and to rate traffic of prospective buyers. Scores for responses to each component are used to calculate a seasonally adjusted overall index, where a number over 50 indicates more builders view sales conditions as good than poor.
