Following the recent c10% fall in its share price I see that Sir David Chapman, Non Executive Director of Zytronic, has seized upon the opportunity to acquire a few shares in the company.

While the purchase of 5,000 shares at a price of 210p per share is hardly likely to encourage wholesale buying it's a vaguely positive sign.

Zytronic the specialist manufacturer of touchscreens and optical filters for electronic displaysis has always appeared to me as a great little business and precisely the type of business for which AIM was really created.

The issue regarding the de-stocking by the group’s largest customer is obviously disappointing but apparently a temporary blimp in the grand scheme of things. Furthermore sales of the group’s key ZYPOS touch sensor product, appears to be going swimmingly and ahead of expectations. The current valuation is really supported by the huge potential for Zypos which seems to have the market to itself. I expect them to really start delivering on all the early promise over the second half of the year.
