Frank asks: Is it correct that you should always be looking for the riskiest and most volatile ETF within one asset class all else being equal? Couldn't tips be a helpful diversifier to treasuries and other assets in certain market environments, e.g. falling rates rising inflation? Are there any limits to the number of assets you should include in a risk parity portfolio? What do you think of my little risk parity experiment? 40% VT, 20% AVGE, 5% EDV, 5% LTPZ, 20% KMLM, 5% GLDM, 5%.
