For the specific problem of strategy inverse correlated with Vix, peraphs you can search in the area short bias strategy/contrarian strategy (not trend following).
I agree with you that is really difficult in general find such reliable strategy.
Also you can use a switching model: use two core group of strategies: trend foll. and contrarian (or value)(also if they doesn't work so efficiently) then use an indicator (ad ex an oscillator of performance of the 2 group) to switch from 1 group to the other.
In practice when a goup is perfoming too much or too little you change strategies weights.I don't know if works but...
For the multi asset class system: Also I'm starting to study this subject, here I think you have to select 2 way.
the first using trend following str. with the important step of good money management.
In practice you want to replicate a classic CTA, but with ETF.
Or create a GTAA, mixing value e trend foll. strategies, with more long trades.
I manage the Pharus Market Neutral Fund, you can also find me on bloomberg Daniele Del Monte (Pharus Asset Manag)
PS: if you work on bond why you don't prove to backtest some strategies on bond?
If you can create a good database (the big problem with bond) you can use metastock explorer to create backtest.
I have not time to try nowbut I hope to make it in the future.
The idea is: write an exploration that give you the parameters you need and one that give you the perfomance, then run it with old date (for exemple every two monts)(with the correct day difference for perfomance) .
then save all the matrix in a excel file: every date / matrix) on one sheet, then with a simple filter you can see the average perfomance of the first X bond.
collect all the two months perfomance for some years then you have an equity line of the simulated fund.
Also when you have tha data in excel you can add some bloomberg link (BDP ) and add in the selection rules fundamental data
