If you are interested in the subject of Business Strategy then it makes sense to subscribe to the McKinsey news letter. I really appreciate their work and this article (The strategic yardstick you can’t afford to ignore), in particular, is a must-read.
The author offers good evidence that 40% of profit variations are simply due to being in an attractive industry. With 60% due to other factors, the best companies in a bad industry perform similarly to the worst companies in the best industries.
As can be expected from McKinsey, there are a lot of charts worth seeing.
