A 66% (or even 73%) increase from what? If you take the share price from it’s highs of over £5 then it’s not an increase. Taken from the lows of around a pound it obviously is. YOY it’s actually up 61% today.
Then it has to be taken into account the fact it’s not paid a dividend in over 10 years. Compound an average 3% and then deduct that from the increase and suddenly the return is a lot less compelling.
Take a look at the directors shareholdings, WW has less than 300,000. Baroness Kingsmill has just 2,000 and Luis Gallego has the grand total of 100!!! What confidence they have in the company!
Institutional investment is less than 25% with the majority being held by Banco Financiero y de Ahorros who are there for historical (Iberia) reasons.
A great share to trade but for long term investors I’d avoid it like the plague.
