I am looking at adding some high dividend yielding stocks (6%+) to the portfolio. I am particularly looking at NGPC, ARCC, ACAS, and PGH. Anyone have any experience with any of these or similiar companies? I am looking for reasons not to buy. They all (except NGPC) have low P/E ratio with a nice divedend. Especially PGH which has 13% dividend yield. As far as the prices they don't seem to move very much but have more perceived upside than downside. Thoughts?
