LF has an ongoing P/E of 7.15, which indicates that it is highly undervalued
First I agree, LF is undervalued but you can't use just the PE alone without being tied to the growth rate. In this case you are right, I low PE with the high growth rate LF has had this year shows the PPS is undervalue. If you look at a company like Apple or Priceline in the days they were growing over 30% in a year a PE of 30 would be low because the revenues would cause the earnings to catch up every quarter. If you had the chance would you buy Apple when Jobs took control @ 42.00 a share with a PE of 40 on a stock that grew to over 600.00 per share.
