For no particular reason other than its very quiet here, looking at a Taleb 15% speculative, 85% safe type asset allocation over a similar time period to that chart you posted, overlaid with another similar allocation that goes back a bit further in time (leveraged ETF history is limited so I had to use non leveraged versions)
Concept being around 7.5% in 2x Small Cap Value (UVT) and 7.5% in 2x Gold, with the remainder in bonds (TIP and 5 year Treasury). But etfreplay doesn't have data for UVT, so these snapshots are proxies (there's not much difference between these and the UVT/UGL versions).
