A simple, dollar-tilt strategy: if USD is weak, tilt between FXI (China) and GLD (gold) by inverse-volatility; if USD is strong, tilt between GLD (gold) and XLU (utilities) evenly. Uses a 21-day window and aims for small, rule-based rebalancing.

- Look at the US dollar signal: compare the short-term trend (8-day exponential moving average) of the USD index ETF (UUP) to its long-term trend (200-day moving average). - If the short-term USD signal is below the long-term average, treat USD as weak and allocate between FXI (China large-caps) and GLD (gold) using inverse-volatility weights calculated over a 21-day window. - If the short-term USD signal is not below the long-term average, treat USD as strong and allocate between GLD (gold) and XLU (Utilities) with an even split, based on a 21-day lookback. - Start from a cash-equal base (equal baseline handling) but keep rebalancing very conservative (tiny corridor, and no automatic periodic rebalancing). - The net exposure is described as “US Dollar vs. Chinese Market” and focuses on two alternate tilts depending on the dollar signal, rather than a plain buy-and-hold equity approach. - Tickers used and what they represent: UUP (US Dollar Index Bullish ETF), FXI (China Large-Cap ETF), GLD (Gold ETF), XLU (Utilities sector ETF).

Out-of-sample, this macro rule-based tilt targets USD signals: it delivers ~52% annualized return vs ~20% for the S&P, with far smaller drawdowns (~6.8% vs ~18.8%), and higher Sharpe (~2.81 vs ~1.10). Simple, disciplined, scalable.
