I'm looking at several companies that still didn't get their 2017 results out. Like for instance Umanis XPAR:ALUMT
So I see, on annual revenue, they have a TTM of 171mm.
I assumed that the number just came from the last registered financial statement (june in this case), but apparently that's not the case since June 2017 revenue was 95mm.
So my question is... is TTM then proyected? if so, how? if not, how did it get that 171?
