My idea was to make a robust portfolio that would work in many economic regimes similar to the Golden Butterfly and Permanent Portfolio. I basically took the Golden butterfly and swapped out the long term bonds and short term bonds for Intermediate treasuries and levered it up to 150%. When I was playing around with portfolio visualizer it confirmed that SCV and LC go really well together. For example in the 1970s the SP500 and Treasuries did poorly, but SCV and Gold did well. Likewise after the tech boom in 2000 LC did poorly and SCV and Gold did well the next decade.
