I tried to do that a while back but I dont have enough data. Point is, I wont wait for the recession declaration or anything like that, but rather to bailout when I asses the risks of a recession are high enough. But this particular return set doesnt depend on recession calls or anything like that. I was curious about the answer to the question 'does it make sense to worry about a correction that arent the result of a recession?', and the answer is that historically it doesnt. Maybe the future will be different but a paranoid fearful investor (one that bails out BEFORE there is any sign of a recesssion in leading indicators) is fighting that is a big historical record. One needs strong reasons to do so because in all likelyhood the odds are that he will be wrongIn my opinion, this is little bit of data mining.
First of all, recessions are declared only after it has already set in, some times it is declared after the economy has come out of recession. In investing, one can not have mulligan. So you need to test returns based on your favorite recession prediction method.
That's a good point. However one could also say that the fact that the US has been strong for so long was not a product of randomness, it was a result of strong institutions, ease of doing business, rule of law, etc, etc. And therefore, the odds will be that its market relative strength will continue. That's the Warren Buffett camp. I dont know if that is right but it does raise the question 'Why should I go against the historical record?'. A strong reason will be needed and most paranoid investors (the ones that want to bail out of stocks without pointing to an imminent recession) do not provide oneYou are also using dataset of one of the best performing country over last 100 years. There are other markets which has lost more than 20% without going thru' recession. In some cases, like Russia and China markets have gone to zero.
So that's the balance I want to strike, to not go "full Tilson" (bullish at the top) but also not to be a paranoid bear (as Rosenberg seem to be now) who is scared of events that are quite rare (corrections that aren't related to recessions)
