Sorry but I am getting lost. Do you remind me what point you are trying to make? I thought we established that institutions attempt to mitigate risk via diversification and offsetting of activities that are in themselves risky. That is hard to impossible to do for most retailers who are investing 50k, 100k, or 500k. Still not sure where you try to get to.
Too what degree should risk be mitigated? If extreme low risk then yeah , it gets complicated
for simple retail mind like mine and probably more risky as size is put on to further diversify
and decrease risk. Correlations blow out and boom.
Simply levering QQQ/SPY in 2015 or your AUD+NZD/USD+EUR (lately, really?),
Or the 2yr/10yr treasury yield spread funded in JPY for the last few years are a couple examples of dozens of risk reducing measures small retail can afford to do in their IB accoumt. Challenge for me is measuring and underestimating the risk I really have.
