Stella,
Cap and trade? It's all about yield. Low growth, low interest rate environment... a company's stock should yield more than it's less risky debt, as Bill Gross says. EXC yields 4.8%, and Bill Gross is buying utilities, so you're in good company, but technically...EXC looks like it has considerably more room to go to the downside, especially if rates rise... which looks likely. P.S. Interesting take on the machinations of the financial world.
