The free fall has been alarming. But it has basically tracked with the market and other utilities. A market correction was probably overdue with $60 oil, huge federal deficits, and back to back expensive hurricanes. Probably not a bad time to consider adding to a defensive position.
The stocks fall does not alarm me. Like you I enjoy the stock's dividend and am a long term investor (3-5 years). Overall I do not expect the market to perform well over the short term. Huge deficits, a tightening Fed, $60 oil, have and will all create strong head winds. I much prefer to be defensive at this point. On a side note I purchased more EDE today. I find the current price appealing.
