How we measure the trend
The 12-month trend is a robust (Theil-Sen) slope of sold prices after removing each sale's trim and model-year effect, so a run of pricier cars does not look like a rising market. The 3-month change compares the mix-adjusted median of the last 3 months with the 3 months before, and the Buy / Hold / Sell signal needs at least 15 sales in each window and a move of 8% or more. These are the same numbers as the market signal on the Porsche 987 Cayman page. It describes recent auction results; it is not a forecast or financial advice. Methodology.
