David Beever, the non-executive chairman of Premier Foods, has made a modest addition to his stake in the group with the addition of 30,000 shares at 38.50p.Spending £11,550 on the purchase, Beever's stake now stands at 304,881.The deal comes just a few weeks after the group reported lower sales and warned that annual profits would be towards the bottom end of hopes.Premier said a loss of market share by the major supermarkets to price-cutters such as Lidl and Aldi in the last few months had affected its sales and volumes.It had also taken a hit from price inflation in the wider grocery market for the 11th month in a row and is expected to soften more.The company's underlying sales declined by 4.7% in the third quarter of the year, with branded sales 4.1% lower. Sales of so-called power brands such as Kipling decreased 5.1% although they displayed an improving trend towards the end of the quarter. Support brands included good performances from Homepride and Cadbury cake.Top Director BuysSacoil Holdings (DI) (SAC) Director name: Mr Thabo KgogoAmount purchased: 330,846 @ 1.93p Value: £6,385Flybe Group (FLYB) Director name: Mr Saad H HammadAmount purchased: 45,200 @ 110.50p Value: £49,946SDL (SDL) Director name: Mr Mark LancasterAmount purchased: 10,050 @ 389.00p Value: £39,094SDL (SDL) Director name: Mr Mark LancasterAmount purchased: 10,050 @ 389.00p Value: £39,094Sacoil Holdings (DI) (SAC) Director name: Mr Stephanus Hilgard Muller Amount purchased: 100,000 @ 1.87p Value: £1,870Volex (VLX) Director name: Mr Christoph EisenhardtAmount purchased: 45,802 @ 65.50p Value: £30,000Flybe Group (FLYB) Director name: Mr Philip de KlerkAmount purchased: 22,250 @ 110.50p Value: £24,586Volex (VLX) Director name: Mr Daren MorrisAmount purchased: 30,000 @ 66.00p Value: £19,800Premier Foods (PFD) Director name: Mr David BeeverAmount purchased: 30,000 @ 38.50p Value: £11,550
