BMW's surprisingly strong third-quarter results add weight to a much contested thesis: that regional diversity may make the auto industry less cyclical. Healthy sales growth in the Americas and Europe offset lacklustre demand in China. BMW's pre-tax profit from January to September rose 4.3 per cent to an all-time record of euro 7.1 billion.
Automotive groups and cycles go way back. If the economy turns sour, drivers can easily postpone the purchase of a new car. Moreover, as fixed costs for carmakers are high, small falls in demand dent profitability heavily.
BMW has diversified supply chains and markets massively in an attempt to reduce the swings. It sells 55 per cent of its vehicles outside Europe, compared to 40 per cent a decade ago. And 30 per cent of all cars are built overseas, compared to 20 per cent in 2004.

So has BMW beaten the cycle? It may have just been lucky. With tighter economic and financial links between Europe, the United States and China, economic cycles may converge over time. The carmaker's financial services units, which generate a fifth of overall group operating profit, also help even out revenue streams.
If BMW can sustainably smooth the peaks and troughs, it deserves a rerating. The shares currently trade on 10 times the next 12 months' expected earnings, roughly at par with its 10-year historical median of 10.1, Thomson Reuters data shows. Engineering giant Siemens, which analysts expect to earn an operating profit margin comparable to BMW's in coming years, trades almost 40 per cent higher.
Closing half of this gap could move BMW shares from euro 93.50 to 112.
