Summary - Episode 401

Finding truly actively managed funds

Past performance of funds can be analysed over different time periods to give insight int how a fund is managed and the biases in the manager's portfolio However it may not give a complete picture.

Alternatively Active Share can be useful in finding funds that are backing their convictions. Active Share measures the disparity between a fund's holdings and its benchmark index. A higher active share means a more actively managed fund. However, calculating Active Share can be difficult as it's not widely available and not all funds publicise their holdings.

Finally tracking error, which is a measure of the deviation of a fund's performance from its benchmark, can also provide insight into a fund manager's management style, especially when combined with the Active Share measurement as summarised in the chart below.

Inflation truths

Highlights:

  • Inflation is a measure of the rate of change of prices over time, not how high prices are
  • The Consumer Price Index (CPI) is calculated by the Office of National Statistics (ONS) from a notional a basket of goods and services. The price of these items is used to calculate the percentage increase in prices over time. Currently the annual inflation rate is over 10%
  • Inflation can appear to decrease without prices actually falling, due to the mathematical calculation of comparing prices to a previous period.
  • High inflation can be controlled through monetary policy, such as raising interest rates
  • Merely reducing the rate of inflation does not guarantee lower prices, it can be a result of mathematics.
  • Government taxation and policy decisions (such as the energy price guarantee) can impact inflation, both positively and negatively
