Sector index

 Sector performance takes into account the contributions of all existing funds the sector comprises of and is therefore referred to as the 'sector index'. The sector index performance may not match the straight average of the existing sector members, as the latter will not take into account the performance of new funds which have entered the sector during the nominated performance period and which would have affected the sector index performance. Over a long period these differences will be cumulative, resulting in wider divergence between the sector index and the straight sector average.
