Apple and Samsung split 109% of mobile phone profits in Q3 by Philip Elmer-DeWitt @FortuneMagazine November 16, 2013, 5:46 PM EST E-mail Tweet Facebook Google Plus Linkedin Share icons Source: Canaccord Genuity.

FORTUNE — According to Canaccord Genuity’s Michael Walkley, Apple AAPL and Samsung managed last quarter to split all the world’s profits in mobile phones – 56% Apple and 53% Samsung — and come up with a total of more than 100%. That only makes sense if you accept two premises: That money lost in a market should be treated as “negative profits” — an oxymoron if I ever heard one. That you can ignore every Chinese mobile phone manufacturer, even though as a group they accounted for more than 30% of units sold in Q3 2013 (see pie chart). Ignoring ZTE, TCL and the other Chinese manufacturers was a matter of necessity, according to Walkley, due to the lack of what he calls “available profit metrics” (i.e. quarterly reports). The question of how market researchers account for so-called Chinese white box devices — often cheap, underpowered knockoffs — has become a sore point for companies such as Apple that don’t believe their high-end products are in the same market.
