LED - will these light up the portfolio?

This is one volatile baby at the moment and certainly not a stock for the fainthearted. Ash says he is comfortable with a pence or two movement, considering this to be a small variation becoming increasingly insignificant in the long run. That said a 12% swing in just over 2 hours trading plus a large spread, gives me a signal of caution. Not a holder at present, but watching with interest. Will join the cautious club for the time being and sit on the sidelines for a while. No doubt kick myself when this takes off like a rocket, sometime early next year!
