In fact, much of the apparent disagreement is a question of semantics, with CU seeing the rate of premium increases tailing off and the level falling in motor insurance.

The two companies may be seeing slightly different points in the cycle, but there is no doubt that the top is in sight even if it has not been passed.
The next cycle will not be as violent as the last because the market is changing and companies are adapting faster, but insurance stocks are at a stage where it is hard to find strong reasons to buy.
