A high-risk tri-asset mix: 60% levered US stocks (SSO), 20% long-duration Treasuries (ZROZ), 20% gold (GLD). Aims for strong equity upside with hedges from bonds and gold; no automatic rebalancing (9% drift tolerance).

- 60% in SSO: acts like twice the daily move of the S&P 500, meaning big gains on strong up days and amplified losses on down days. The long-run path can diverge from simply doubling the index due to daily compounding. - 20% in ZROZ: long-duration, zero-coupon US Treasuries. Very sensitive to interest-rate changes. If rates fall, ZROZ tends to rise a lot; if rates rise, it can drop sharply. This adds a bond-like hedge to some market scenarios but also adds interest-rate risk. - 20% in GLD: gold, a traditional hedge against inflation and market stress. It doesn’t pay a dividend and can be volatile in the short term, but it provides diversification away from equities and bonds. - Rebalance: corridor width of 0.09 means weights can drift by about ±9 percentage points before rebalancing would be triggered, but this strategy is configured with rebalance set to none, so it remains mostly static unless manually adjusted.

Out-of-sample, this levered 60/20/20 mix delivers bigger upside with stronger risk-adjusted gains than the S&P 500: ~72.7% annualized vs 44.2%, Sharpe ~3.36 vs ~2.97, Calmar ~10, and max drawdown ~7.3%.
