Monthly Momentum · the models

Two models. Both beat buy-and-hold on return, with far less drawdown.

Monthly Momentum comes in two models, Growth and Preserve, built from broadly commission-free ETFs so they trade at any brokerage. Every chart and every data point was backtested across multiple cycles, net of conservatively-estimated costs.
