This application demonstrates how to back-test a ETF Sector strategy using Shiny framework and Systematic Investor Toolbox . This example is based on the Multi-Asset Backtest : Rotational Trading Strategies post.
The Sector Rotation strategy selects top N funds (i.e. 2 funds) based on the momentum (i.e 6 month returns) and adjusts the holdings only if these funds drop their momentum rank below a threshold (i.e. replace all holdings with momentum rank greater than 6). This study is based on the ETF Sector Strategy post by ETF Screen
