This is because it is only as good as the numbers that go into it. There is no debate about the “p” in the equation – price is quoted every second. But the “e”, though readily available, is only as good as the best estimates. http://www.valueinvestingnews.com/look-margins-when-using-price-earnings-r#comments Commentary Mon, 12 May 2008 19:42:03 -0400 kenkid 4199 at http://www.valueinvestingnews.com
