Teaser
Hold each liquid ETF only when its price is above a long SMA; equal-weight the longs, cash otherwise. Universe: BTC-USD, ETH-USD. Parameters: sma_days=200; rebalance=monthly. Rebalanced on the engine's template schedule with 5 bps commission and 2 bps slippage.
Strategy in a nutshell
Momentum-based trading strategies are widely employed in financial markets and have become increasingly relevant within the cryptocurrency ecosystem. This study examines the profitability of momentum-based trading strategies in cryptocurrency markets using a multi-horizon exponential moving average (EMA) framework. The analysis covers eight major cryptocurrencies, Bitcoin, Ethereum, Litecoin, Ripple, Binance Coin, Cardano, Dogecoin, and Solana over the period 1 January 2020 to 31 October 2025. Momentum signals are constructed using short- and long-term Exponential Moving Average (EMAs) combined with volatility normalization to ensure comparability across assets. Two portfolio structures are evaluated: time-series momentum, which adjusts exposure for each asset individually, and cross-secti
Economic rationale
Trend filters exploit persistent serial correlation in asset returns and reduce exposure when prices fall below a long-horizon average, cutting left-tail risk.
