When you now cannot fault the business model and execution...

When you now cannot fault the business model and execution pursued by management doubt can only be sown in the minds of holders by putting forward worries like valuation and competitors.
Holders should expect this type of research and misdirection to continue.
My thoughts are that this company has years of growth ahead and will now in all likelihood create great wealth for long term holders. IMO and please invest according to your risk appetite.
My change of investment strategy 5 years ago trying to envisage what the future would look like and then find good companies and management has finally with ISX paid off. It has been tough hanging on but am very pleased to be vindicated.
