EMI triggers a rebalance when the 10 Day Simple Moving Average (10 SMA) of the Ethereum/USD ratio crosses the 50 Day Simple Moving Average (50 SMA) indicating a trend reversal. If the 10 SMA crosses and stays below the 50 SMA, EMI rebalances all Ethereum tokens into USD to reduce further underperformance in the downtrend. If the 10 SMA of Ethereum crosses and stays above the 50 Day SMA, EMI rebalances back into Ethereum to capture the upside in the uptrend.
