Summarising 2020 from any perspective is near impossible, especially when considering investment performance. The impact of COVID 19 and subsequent shifts in risk sentiment, fiscal policy reaction through bail-outs and the US elections have resulted in extreme sentiment swings, unbelievable opportunities and subsequent overvaluation. The JSE was up for the full year but lagged developed markets, why? The full year style note looks to document the impact of the idiosyncratic events on SA equities through the analysis of style performance on the JSE. Additionally, in our datascience segment, we evaluate our model output from the Q3 note and provide model driven estimates of style performance over the first quarter of 2021.
