My theory is to sell if I see a 5% drop or more from the current prices. PHK and PHT have fallen more than this in the last 2 weeks. You can always buy these back at a lower price.
Just a general comment to me it seems that EOS is somewhat safe along with NLY and ARR. Also PMF a PIMCO Bond fund maybe a good place to put your money.
Once the market bottoms out buy back what you have sold at lower prices. Once again look at the 3 to 5 year lows on bigcharts.com
