The VYM is a good fund (solid portfolio w/ good yield). If you're looking to add some diversification, I would look into the PIMCO High Income Fund (PHK); it's a closed-end fund that is currently yielding 11.40% @ $12.83. The NAV to Mkt price premium is pretty high though (NAV $9.25). Check out its dividend payment-pretty solid. This fund’s market price has been a little volatile lately so it may be worthwhile to stagger your investment into this with a few limit orders at different levels
