A new mobile phone market index

Measurements of “share” are abundant. There is journalistic value in summarizing performance in a single figure of “share” but it usually is a very limiting view. For example in the global mobile phone market there are at least the following measurements available:

  1. Share of all handset units sold
  2. Share of installed based of handsets (penetration)
  3. Share of smartphones
  4. Share of mobile computers
  5. Share of value (revenues) captured
  6. Share of profits
  7. Share of platforms
  8. Share within a given platform
  9. Share by regions/countries/geographies/demographics

One could go on. So performance in a market can only be measured if you know to what end is that measure applied. Are you trying to determine current performance or are you assuming that the future will be different and trying to figure out what that future will look like?
