Pension fund returns

Can anyone help me understand the difference between the "Trailing returns" number and the chart information (for example on Morningstar).

e.g. - looking at fund "HSBC FTSE All-World Index Fund Accumulation C", the 1 year performance trailing returns is 6.01 but if I set the chart screen to 1 year, it appears that it grew by 7.01%.  If I set the chart to 3 years, I see growth of 31.19% so 10.39% per year, but the training returns performance number is 7.69%.  

What is the difference there and which one should I be paying most attention to?

    The Trustnet charts and data match at 6.1% and 7.69%. The Morningstar table data agrees with Trustnet. Which Morningstar charts are you looking at? 


    31.19% over 3 years is 9.47% per year - it is compounded.  But that is not sufficient to explain the difference.

    Got it I think…

    The Morningstar X-ray data is only updated once a month so its chart is currently showing up to end September 2023.

    I wondered if that might be the case - it is the interactive chart on the "chart" tab that was showing different numbers to the "performance" tab.  That said, I also changed the date to 1st October 2022, to 30th September 2023 on the interactive chart and the number still didn't match.

    What is the Excel formula then to calculate that reverse compounding?

    3) Annualised 3 year trailing data on performance page =9.05%

    From trustnet for period up to 30 sep 2023
    1) Chart shows overall return approx 30%

    Trustnet period 27/10/2020 to 27/10/2023
    1) Chart shows overall return approx 25%
    2) Table shows 24..9% 3 year return

    I am not using the portfolio xray as it's a paid feature (although I might have access to the data from it through II, but it will be locked to my II portfolio).  

    I am just doing a fund search and looking at that one fund, and then clicking "chart" on the left.  However looking closer, if I manually change the chart dates, it seems to only allow me to pick days which are a Friday.

    However as of today - the chart when clicking "1 year" shows the same figure (6.1%) as the trailing returns on the performance page, so I'm maybe thinking its more an issue of the data on each page getting updated at different times of day.
