From Todd Dills, Overdrive:
Every Wednesday, Diane McHaney downloads average-rate data from DAT Solutions. As an analyst for Barton Logistics, a brokerage based in Bandera, Texas, she identifies trends in spot and contract freight markets.
Of particular interest is the mode — the most frequently occurring value in the data set. Also important is the standard deviation of DAT’s rolling 15- and 30-day spot market average-rate data. Both indicators help identify early signs of rate volatility.
