Hi S, NRO's not been this low since sometime in early 2016. Yield percentage goes up when the price/share goes down. I like it when it's north of 9%. I added 12% more shares back in early Feb at $4.59. Not a big change in price/share since. I'll add a similar amount if the price declines to around $4.
For now I'm content to have averaged down in price/share and averaged up in yield.
