SPY = S&P 500
FGD = global dividend stocks
DVY = US dividend stocks
FDD = European dividend stocks
DEM = emerging market dividend stocks
These charts plot the ratio of the performance of each fund to the performance of SPY. That provides both a view of relative performance of the dividend ETFs to each other, but also the relative performance of each to the leading large-cap U.S. stocks index (S&P 500).
