RE:How sustainable is this dividend?The dividend on this can fluctuate, but it won't fluctuate a crazy amount.
It can go up and down with the market and the underlining securities that it holds.
It depends on the covered call income get it changes with market conditions..
Considering it's basically out of five-year low, I don't think it's a huge risk to add here. ( can't really get much worse for that utility telecom sector )
