(ShareCast News) - Chemring chief Michael Flowers picked up 15,000 shares in his company on 11 August, at an individual price of 133p each, for a total disbursement of £19,950.The manufacturer of military countermeasures and electronics reported an 11.3% rise in first half 2016 revenues to £180.1m on 20 June, alongside a 23% reduction in net debt to £114.4m.Despite the above, the company incurred in a loss and management warned that the fiscal year 2016 outturn was likely to be slightly below market expectations.On 20 July, analysts at JP Morgan raised their target prices for several of the aerospace and defence companies under their coverage.In Chemring's case they bumped up their target from 124p to 130p.Overall, they expected several trends to become apparent in the sector after the companies updated investors on their progress in the second quarter or at the half-year stage.Among those trends, they expected 2016 to mark the trough for the decline in US defence spending which began in 2009 although there was some risk from a "likely" Continuing Resolution in the backhalf of the year, a foreign exchange tailwind from pound weakness and increased IFRS pension deficits.Top Director BuysMx Oil (MXO)Director name: Olivier,StefanAmount purchased: 5,000,000 @ 0.99pValue: £49,500.00Stock Spirits Group (STCK)Director name: Maloney,DavidAmount purchased: 20,000 @ 164.30pValue: £32,860.00Stock Spirits Group (STCK)Director name: Jackson,LesleyAmount purchased: 20,000 @ 163.00pValue: £32,600.00Mx Oil (MXO)Director name: Olivier,StefanAmount purchased: 2,500,000 @ 0.95pValue: £23,750.00Mx Oil (MXO)Director name: Olivier,StefanAmount purchased: 2,500,000 @ 0.93pValue: £23,250.00Altitude Group (ALT)Director name: Hallett,Peter Amount purchased: 135,000 @ 17.00pValue: £22,950.00Chemring Group (CHG)Director name: Flowers ,Michael Amount purchased: 15,000 @ 133.00pValue: £19,950.00Schroder Real Estate Investment Trust Ltd (SREI)Director name: Bligh,StephenAmount purchased: 25,000 @ 54.95pValue: £13,737.50U And I Group (UAI)Director name: Shepherd ,Marcus Amount purchased: 3,013 @ 164.90pValue: £4,968.44Zotefoams (ZTF)Director name: McGrath ,Gary Amount purchased: 57 @ 265.25pValue: £151.19Zotefoams (ZTF)Director name: Stirling,DavidAmount purchased: 57 @ 265.25pValue: £151.19Share Plc (SHRE)Director name: Ecsery,Francesca Eva Amount purchased: 517 @ 29.00pValue: £149.93Share Plc (SHRE)Director name: Thomas ,Gareth Amount purchased: 517 @ 29.00pValue: £149.93Share Plc (SHRE)Director name: Stone,Richard WilliamAmount purchased: 517 @ 29.00pValue: £149.93Share Plc (SHRE)Director name: Birkett,Mike Amount purchased: 517 @ 29.00pValue: £149.93Share Plc (SHRE)Director name: Tolkien,RichardAmount purchased: 517 @ 29.00pValue: £149.93Top Director SellsTelit Communications (TCM)Director name: Fait ,Yosi Amount sold: 632,998 @ 267.55pValue: £1,693,586.10Telit Communications (TCM)Director name: Fait ,Yosi Amount sold: 210,227 @ 265.01pValue: £557,120.27Greggs (GRG)Director name: Hutton,RichardAmount sold: 41,170 @ 1,050.00pValue: £432,285.00Telit Communications (TCM)Director name: Fait ,Yosi Amount sold: 140,152 @ 265.07pValue: £371,501.32Telit Communications (TCM)Director name: Fait ,Yosi Amount sold: 29,648 @ 272.54pValue: £80,802.78Churchill Mining (CHL)Director name: Radke,GregoryAmount sold: 22,000 @ 27.00pValue: £5,940.00
