$XDEM (+0,53 %) Momentum ETFs are fun when the momentum repeats. We are probably on the verge of a Momentum Change. I wonder if on the next rebalance the fund Will reajust enough for the new upcoming momentum, that is what Will make any decision to either keep using it or not. From what I have read, I fear there might be a 6 month lag on a proper readjustment, lets wait and see.
