Thanks to a reader’s suggestion, I took another look at the profit and market share data from the mobile phone market overview posted last quarter. This time to compare the vendors on two dimensions at the same time.
I plotted the vendors on share of market and share of profit axes in two different points in time: Q2 2007 and Q2 2010. I further broke the chart into four quadrants as shown:
I chose to label the quadrants to indicate the possible categorization of the companies.
- Dominant: large market share and large profit share
- Star: low market share with large profit share
- Fading: high market share with low profit
- Marginal: low market share and low profit
It’s interesting to note the shift over the time period of the eight vendors. Whereas Nokia moved from Dominant to Fading, only Apple rose from Marginal to Star. The Marginal players dispersed their placement with Samsung moving laterally toward Nokia while RIM followed in the Apple trajectory and increased profit share while maintaining relatively low share.
Thinking about motion around these two dimensions could be reduced to a vector model. If each vendor is represented by an arrow showing direction and distance moved, we can compare each vendor vs. a symmetric competitor which might account for the loss or gain of share.
The vectors can be paired as follows:
Although the data does not contain all market participants, the shifts in share are quite closely conserved with the vector magnitude (arrow length) and angle (direction) paired. Note how Nokia and Apple swapped Profit without too much impact in Units volume. Similarly, RIM and Sony Ericsson traded profits and volumes quite symmetrically. Samsung also took volume while Motorola lost it. HTC and LG did not change positions dramatically.
Finally, moving all vectors to the same origin leads to this view of share gain/loss over three years in two dimensions:
It becomes quite easy to see who the winners and losers are and by how much.
This model is only an observation of the shifts in market power and is not conclusive about where share was gained or lost, however there is compelling symmetry which also matches the intuition of observers."
