Well, that didn't work out so well UMM closed at 21.83 and DMM closed at 24.90 for a combined value of 46.73. That is a $3.27 net loss from the original $50.00 issue price. Looks like that way of eliminating decay on index prices over time got eaten up by costs. Case to the wary on ETF's, watch out, there are several ways to skin a cat, and they will try to sell you them all.
