Portzo compares fund values over time
Portzo performance figures are based on changes in fund values across selected time periods. In simple terms, if a fund value rises from one date to another, the return is positive. If it falls, the return is negative.
Different pension providers may publish data in different formats, with different update dates or naming conventions. Portzo aims to make those figures easier to compare by using consistent periods where data is available.
Performance can be shown over periods such as one year, three years or five years. Longer periods can sometimes give a better sense of how a fund has behaved, while short periods may be more affected by recent market conditions.
Why numbers can differ
Returns may differ from provider websites if data was captured on a different date, if a provider uses a different calculation method, or if charges, unit prices or fund share classes are treated differently. A small date difference can matter, especially when markets move quickly.
Portzo performance information is educational only. It can help you compare and ask better questions, but past performance does not guarantee future returns and should not be used on its own to choose a pension fund.
