A retired friend of mine has shares in this company and wonders if this is the right time to sell.
Any advice would be appreciated.

Looking at IPR charts of to-day I would think it reasonable to let this share run a little further with a trailing stop loss of 2-5% if you can set this up with the stock broker.
But like many I am guessing!

Thanks for that.
I do believe the shares were free issue as he was an employee, but I will pass on your views.
