All the utilities got hit. They have had a huge run and there is profit taking and some rotation to other sectors. I doubt there will be much in the way of gains in share price for a while. Last July the stock went from a high of 41 to 36 for the same reason. It is a solid company and the management continues to beat the analyst's estimates every quarter. These utilities (like VVC, SE, OGE) that have predictable earnings and dividends along with companies like CL, WM, SE give stability to portfolios. Then you can speculate with shale oil plays and biotechs.
The annual return on YOUR investment will continue to rise from the current 3.1% regardless of what the stock price does. If you don't need the principal back in the near-term, just sit and enjoy the ride as your percentage dividend on YOUR investment in the stock rises.
