The original article cited by Alpha Architect used 7-10 Treasury Bonds for the bond holding. I chose a broad-based bond bond (BND) in lieu of a 7-10 year treasury ETF like the iShares 7-10 Year Treasury (IEF).
Also, the Alpha Architect article timing signals for both the value and momentum equity positions were based on the moving average of the underlying index. For US equities the S&P 500 TR Index was used and for international equities the EAFE TR Index. I chose to use the moving average signal of the actual value and momentum ETFs.
