I'm trying to do something similar by ocasionally getting involved on the short side and changing the weightings of my risk parity allocation. But with shorts, its tough. Since 2009 there has been few significant drops. There was 2011 where the market dropped 19% or so, then 2016, where it dropped some 15-16%. I think in 2014 there was a 10%+ drop as well. All of these stock drops ultimetly were failed pullbacks, markets perked up and went to new all-time highs. You had to time super well (the little small losses trying to catch them can add up) and you had to be good at taking profits, otherwise quickly those profits were gone.
Bonds barely dipped until recently, there was the Taper tantum in 2013 but they were on a tear for a long-time until that. Anyone looking to short them accumulated a lot of little losses. And they had to be quick taking profits otherwise those losses weren't paid by the profits. Overall, the enviroment that US assets currently face is not of of a lot of macro dislocation, but rather an enviroment where beta (indexes), "beta plus" (illiquid assets like real estate, private equity) are doing well. So macro 'alpha' is hard, there is not much of that, at least in the US. But at some point beta chasing will end badly and we see a lot of dislocation. At this point I'm not seeing the catalyst to make that happen, I still think it will be a favorable enviroment for beta, beta plus and levered beta (although the latter might face some difficulties due Trump's volatility)
But at some point down the line I do plan to protect myself against dislocations by putting in big shorts and underweighting certain asset classes. I just don't want to be early, until a big catalyst shows up there is no reason to fear beta
