Martha Wyrsch, a Non-Executive Director of Spectris, the FTSE 250 instrumentation and controls company, has purchased her first set of shares in the company. Wyrsch, who took up the role in June last year, acquired 3,000 shares at 2,029.00p each for a total value of £60,870.The transaction was made Wednesday, one day after the company was upgraded by Investec from 'hold' to 'buy' on the basis of the company's confidence of a bounce in second quarter revenues. Spectris reported an eight per cent fall in sales for the first quarter, reflecting a deferral of orders and shipment delays, and weak customer confidence across all its major regions in the first three months of the year.Looking ahead, it expects revenue growth in 2013 to be below its previous forecast.
