My post was confusing so I edited it slightly.
My point was that NML's NAV dropped 2.4% last week, from $ 8.41 down to $ 8.20. But because its discount shrunk from 13.9% to 10.6% during the week, its price actually rose 1.25%, from $ 7.24 to $ 7.33..
So NAV down but price up.
There may be an explanation, though. A lot of midstreams went ex-dividend last week, including a bunch that NML owns. I have no idea how the CEFs account for the ex date. I would think they accrues the distribution, to offset the ex-date price drop, but I don't know. When I looked at NML's top 5 holdings, I didn't see anything that would account for the large loss in the week. But NML owns 27 holdings and I didn't look at them all.
