I never look at TTM because it doesn't tell me anything about expected growth. I also don't like forward P/E because it points to next year. And two days from now that means 2014.
It seems that nobody is interested in "current" P/E. Meaning, 2013 two days from now. Usually the company will provide some guidance during the course of the year so I don't see the problem. And it's not like we are clueless either.
So, when we talk about (current) "P/E" I prefer to use 2013. In two days, that is.
Current P/E = 0.52/1.08 = 0.48.
The rest is pretty much meaningless IMO.
Or you could take the past two quarters and the next two quarters to get a meaningful number. But I will just take 2013.
