Weighing up the odds of investment risk
Investors often assume that any equity portfolio that deviates greatly from the index increases its underlying risk. This is a very simplistic view to take of investment risk. In reality, by deviating from a specific index, a portfolio manager takes a more active position and this increased risk creates an increased capacity to generate excess returns. The scale of the deviation from the benchmark index is called tracking error. Portfolio managers will need to decide on the level of risk they are willing to take in order to achieve returns.
