Comparatively, VST’s free cash flow per share was +0.26. On a percent-of-sales basis, PPL’s free cash flow was -1.1% while VST converted 2.16% of its revenues into cash flow.

PPL is the cheaper of the two stocks on an earnings basis but is expensive in terms of P/B and P/S ratio. Given that earnings are what matter most to investors, analysts tend to place a greater weight on the P/E.

Analyst Price Targets and Opinions

A stock only has value if the current price is substantially below the price at which it should trade in the future. PPL is currently priced at a -10.84% to its one-year price target of 39.68.
