WPL was $38-44 in 2006 so basically the share price has gone nowhere, even backwards, since then. Was once a holder in the early years. All the good assets have not done the share holder much good, other than a reliable dividend now. I guess if you are happy with 3-4% divi and not much else then it is OK. Had some dealings with WPL and found them to be very slow to take up new ideas (laggards). I am not shorter and not a buyer at any price.
Many of the large caps have done poorly over 5 years (eg banks), there are a few notable exceptions. But 10 years is a long hold for no capital gain. Good luck with it anyway.
