Dagens avsnitt bygger på Credit Suisse Global Investment Returns Yearbook 2021 (hela rapporten i pdf). Något som verkligen stack ut för mig var följande:
Framtida förväntad real avkastning
Den här bilden är nog första gången jag ser i det här formatet. Det känns som att det här är ganska relevant. Särskilt när man i genomsnitt räknar med 7-8 % (nominell) avkastning på aktier.
Aktier är inte någon bra inflationshedge
Min upplevelse när man lyssnar på andra så sägs det alltid: “aktier är ett bra skydd mot inflation”. Citat från rapporten (min fetstil):
Overall, it is clear that equities performed especially well in real terms when inflation ran at a low level. High inflation impaired real equity performance, and deflation was associated with deep disappointment compared to government bonds.
These results suggest that the correlation between real equity returns and inflation is negative, i.e. equities have been a poor hedge against inflation. There is extensive literature which backs this up.
Yet it is widely believed that common stocks must be a good hedge against inflation to the extent that they have had long-run returns that were ahead of inflation. But their high ex-post return is better explained as a large equity risk premium.
Sågning av faktorer (smart-beta)
De hade inte mycket övers för att övervikta mot faktorer.
First, although these are labelled premiums, they are frequently negative. At best, factor investing is a long-term strategy. Second, over time, the ranking of the factors varies a great deal. Third, and relatedly, although the rankings within a year for the two countries are often similar, that is not always the case.
For example, in 2017, low volatility did best in the USA but worst in the UK. Fourth, it is not obvious which factors are destined to do well. There can be a successful run of years, but it is hard to know if it will persist. An interval of 13 years is simply too brief to underpin judgements about the longer-term premiums from a particular factor.
Det var mina höjdpunkter. Vad tänker ni? Eller något annat som stack ut i rapporten?
