We gave DoubleLine Opportunistic Credit Fund (NYSE:DBL) a look last summer, and we had looked at the other DoubleLine closed-end fund offerings at that time. Since then, the performance of the fund has been quite strong. The fund has moved to start trading at only a slight discount, but historically speaking, that actually means it isn't looking expensive. The fund has consistently traded at a premium - even higher premiums than we are seeing now on occasion. The fund provides investment exposure to a diversified pool of fixed-income instruments.
