The review, which does not yet have a fixed date, will look into the likes of trackers and ethical funds and whether they warrant a place in the sector.
The trade body made the announcement in a circular to clients regarding the splitting of the IMA UK equity income sector.
The document, seen by Money Marketing, says that for now the IMA believes it would not be of benefit to consumers or their advisers to move tracker funds across other equity sectors.
A spokesperson for the IMA says work on sectors is always ongoing but would not comment further on the review.
Baronworth Investment Services director Colin Jack- son says: “If you put more funds together, it is easier for clients to compare rather than having to compare between sectors.”
