Agree jogo. If we look at the PE ratio before the "'China Craze" happened, say Yrs 2009 - 2014 Blackmores traded on a PE band of around 12-20. If we use the mid point of 16 and multiply it by 2019 EPS of 3.08 = $50 approx.
For me that represents the a starting point. So close to $50 and I will start to take a look.
