As asset managers gird themselves for the publication of the Financial Conduct Authority's review of the sector on Wednesday, there are four main points of detail to look out for. Some are complicated and all are controversial. But if implemented correctly, they have the potential to achieve long-lasting positive change.

The first two are what you might call "sunlight remedies". Perhaps the most contentious remedy proposed by the FCA in its reports so far was the idea that UK-authorised mutual funds should be required to adopt a single, all-inclusive charge. This would improve comparability and competition, which would be good news for consumers.
