Value Retention
How well a Power generation holds resale value on the active secondary market relative to its original cost.
IBM does not publish resale value data, so this site models Value Retention from observed dealer listing activity and volume (Alta Technologies, Spectra, Flagship Technologies, and comparable resellers). It is a 10%-weighted input to the Power Value Index.
