Yes, indeed interesting. I remember having read an UBS paper this year with long-term statistics (>100 years) about different factors. They all work somehow and they all have very long periods that they don’t work. Those periods were shortest in the momentum factor which was the overall winner.
Personally I use a combination of momentum, value and carry. But then I FIREd already 11 years ago, so my situation is probably not like most others. Half of my money (it used to be 80%) is in a boring dividend strategy with the target of low volatility and high income. The other half in a high risk momentum/growth strategy. Both are completely mechanical to avoid behavioral risk. The risk paid out well, this year it overtook my dividend strategy in value, compounding in action.
I try to do a monthly update on my investments here:
