RE:clarificationMeh, not so fast there. Just quoting the source I mentioned (TD waterhouse - as well, saw a P/E from another source yesterday and today listing 3.94). They didn't have those numbers in the trailing. As well, research reports are quoting their current P/E as being lower versus their peers.
Book value is a metric as well. Whether you use it or not, does not discount it for others. I don't base my buying/selling decision based on it. But I use it as a guage when trying to evaluate whether a stock it mispriced. Just because a stock is down, doesn't mean it is still good value. In a sense I use it to judge how compelling an upside may be versus a downside risk. It is a one measure of a company.
