It's called 11.11, not 10.11, not today! Because the one child policy and family in favour of boy over girls! In the past few decades, Chinese had imbalances between genders! Many males are left single, demand is enough for a special sales day to be created in 11th November! However, I fail to see any link between that and Bellamy share price raise today! One would expect 12.12 to be big for formula players! 11.11 to be big for other entertainment related product?!
My thought on the rise is the penalty is way less than anticipated, hence the rerating today!
