Can anyone explain Trustnet's figures?

I found Trustnet useful to view unit trust prices by sectors. It gives growth figures for the sector by over a number of time periods (I think!). But, when clicking on any sector it shows a graph with different growth figures for the same time periods. Is this just unreliable or am I misunderstanding something?

    The more one looks the more wrong it looks. For example if you look at the "Top ranked by 3 year performance" list you will find it is completely different to the top 10% in 3 year performance taken from the full "constituents" list.

    I also looked at their other tables and found several inconsistencies, and it seems to me that it is the top level analysis that is wrong. I used Trustnet a lot for selecting unit trusts but now I have no faith in their tables.
    Can anyone recommend another site for analysing unit trust performance?

    When charting you need to look at the periods in question. For example, some figures will be to the end of the last quarter. Whilst some will be to close of business to last night. Some may be by calender year. Others may be by running year.

    You then have to see if they include income reinvested or distributed and make sure the tax wrapper information is correct (gross, net etc).

    I use the paid for version of Trustnet and it is very reliable. However, you have to be careful that you know what you are looking at. I would put most errors as being "to end of last quarter" vs "to latest price".

    edit: just looked at figures using the N America Smaller cos....

    Trustnet front page - leading sectors says 49.0% over 5 years
    FE has 38.56% cumulative until month end
    FE has 44.64% as a rolling 5 years looking at sector (26-01-2007 to 26-01-2012)
    Trustnet graph has 44.0% when looking on the sector profile (29-01-2007 to 27-01-2012)
    FE has 44.01% looking at last 5 years of that sector (26-01-2007 to 27-01-2012)
    FE manual input of 26-01-2007 to 25-01-2012 is 44.54%

    So, you can see variations on the figures using slightly different ways of reporting the figures. Trustnet do not state what the front page figure is based on.

    The principle of what you say is clearly correct, but I don't believe it is relevant to what Trustnet are doing. Look at the more obvious case of IMA Specialist sector. The figures above the graph show 7.8% growth over 1 month which looks fairly close to the graph from 25th Dec to 25th Jan (approx). Now look at the front page number showing growth of just 2.8% over one month. That's a big difference and the 2.8% is not the same rolling month, nor the calendar month of Jan, nor the last full month of December. There's no obvious reason - or perhaps you can tell me.
    And why would anyone change definition of such closely linked tables? The table is just shifted one column to the left (or right). The 3m, 6m and 1yr figures of 7.8%, 2.6% and -6.1% become 1m, 3m and 6m. Very precise numbers -- is that coincidence? It changes the whole structure of the league tables.
  • Thank you for identifying this everyone.

    Thanks for sorting this out so quickly, Trustnet. Now I can trust the thoroughness of my own charts (based on yours) and avoid the IFA's a while longer.
    FYI I had reported it to "clientsupport" about a week earlier but nothing was happening - hence the posting on MoneySavingExpert and with surprisingly quick results.

    So perhaps trustnet can get on to staff training as those who are supposed to monitor user complaints aren't doing their jobs ;-)
