I don't know why anyone would use such terminology as 'Q1 FY19', it's Q3 2018 in my opinion. Anything else is just confusing and a good example of extreme dickheadedness. (Unless I am missing something?) If you're in a business meeting people just say Q1 2018, Q3 2019 etc etc. You can easily confuse everyone with 'FY' talk because different countries and regions around the world have different financial years. Apparently the Argentinian fiscal year is the same as a calendar year, so yet another reason to keep it simple, stupid.

The SP has bounced off the previous recent low of $3.30 this morning so hopefully that's the end of the selloff, although somehow I don't think we're out of the woods, because we haven't seen the quarterly yet.
