When a market has risen for seven months on the trot, and 9 months out of the last ten, it could be deemed to be churlish to consider that all is not quite what it seems. Yet the nagging suspicion remains that growth in the second half of the year will be much harder to achieve than it has been over the opening six months. Sales to June were 5.4% ahead of last year at 4,431,292 from 4,205,515, and although growth in June itself was a less impressive 1.8% at 836,629 from 822,186, that was still the best result for the month since 1995. So why the pessimism?
