Highly leveraged with a healthy high yield portfolio. When the bears start to run, those in it will be in a world of hurt. I will stick with my PIMIX/PONAX and sleep better.
Technically (and more from the top of my head than bc I am delving deep into their portfolio), PDI, PCI, and it's PIMCO CEF cousins are mostly NOT high yield funds. They make a lot of their return on smartly-purchased MBS, but also on swaps and derivatives that both hedge their portfolios to swings in interest rates and add to their returns. Look at the performance of their NAVs on days when interest rates rose.
As far as premiums go, think of PDI as the equivalent of a single bond. (I know I know it's not! Just work with me here....) Would you rather hold a bond that matures in, say, 10
years (I know PDI doesn't mature and return your full par value.....just an exercise), and pays 8% interest along the way (again, I know it's distribution is not fixed like a bond....), or would you rather own a bond with similar maturity that pays 4% interest along the way? Leaving out price of the bond. The yield-starved market is pricing these CEFs that earn 8-10% on their NAV, at premiums, that still allow an ~8.5% distribution (give or take a %) on current price. And yes, prices are volatile compared to their NAVs or to OEFs.
Just my thoughts. Currently hold PDI, PCI (bought later 2 just yesterday for a small account I help manage), PFN, PTY, PKO, for full disclosure. But I would also like to see their prices decline some so I can purchase more in various accounts. So talking them up defeats that purpose some ;)
Lastly, on the topic of "highly leveraged", is a fund that holds bonds picked by arguably the best bond-picking managers/team around presently, levered up 1.5-to-just-under-2 times, really a bad thing? Plus managed with "the full toolbox" available to bond managers today--hedges, swaps, derivatives, so dampen the effects of macro interest moves. mREITs are often levered up multiples of that and generally much less diversified in their holdings.
Finally, and yes, then I'll get off my proselytizing soapbox, for those who worry about asset gathering and forced redemptions, these CEFs do not deal with that, as success leads to investors purchasing the fund, driving up the premium perhaps. Conversely, sales do not force the managers to sell to meet redemptions. These are $1-2 billion-sized Ivascyn funds (best of ideas maybe? Or at least able to invest across the spectrum of holding sizes/availabilities). Imagine investing in PONDX/PIMIX when it was only this size.....
