(ShareCast News) - Rupert Soames, Serco´s boss, picked up a large amount of shares in the company he captains.The outsourcing group´s share price had risen against a falling market year-to-date, following a very poor performance over the past three years.On 25 May, the company said it expected underlying trading profit for 2016 to come in ahead of current market forecasts following a stronger-than-anticipated start to the year.Soames bought 120,000 shares at an individual price of 107p for a total outlay of £128,400.01.However, Soames sounded a very cautious note, saying that while the first four months of the year had been strong in large part thanks to the successful outcome of a number of commercial negotiations, the nature of most of the items driving the stronger performance was that they would sharply increase profits in the first half, but would not repeat in subsequent periods.Exane BNP Baripas analyst George Gregory disagreed."We remain of the view that guidance for FY17 remains conservative: our revenueestimate reflects a c33% win rate on extensions, a similar level of wins to FY16, as well as a cGBP40m buffer, while our trading profit estimate reflects further gross margin erosion," Gregory said in a research note sent to clients and dated 26 May.Top Director BuysTribal Group (TRB)Director name: Bowles,IanAmount purchased: 909,597 @ 53.50pValue: £486,634.42Serco Group (SRP)Director name: Soames,RupertAmount purchased: 120,000 @ 107.00pValue: £128,400.01British Land Company (BLND)Director name: Adams,AubreyAmount purchased: 10,000 @ 730.00pValue: £73,000.00Yu Group (YU.)Director name: Parker,Nick Amount purchased: 20,300 @ 245.00pValue: £49,735.00Blackstone/gso Loan Financing Limited (BGLF)Director name: Clark,Gary Amount purchased: 28,700 @ € 0.94Value: € 26,978.00Lloyds Banking Group (LLOY)Director name: Culmer,GeorgeAmount purchased: 22,156 @ 40.62pValue: £8,999.77Jpmorgan American Inv Trust (JAM)Director name: Bragg,Simon Amount purchased: 435 @ 290.54pValue: £1,263.85Centrica (CNA)Director name: Hodges,MarkAmount purchased: 75 @ 202.56pValue: £151.92Henderson Group (HGG)Director name: Thompson ,Roger Amount purchased: 56 @ 267.76pValue: £149.95Henderson Group (HGG)Director name: Formica,AndrewAmount purchased: 56 @ 267.76pValue: £149.95Centrica (CNA)Director name: Hanafin,MarkAmount purchased: 74 @ 202.56pValue: £149.89Centrica (CNA)Director name: Shedden,JillAmount purchased: 74 @ 202.56pValue: £149.89Lsl Property Services (LSL)Director name: Gill,AdrianAmount purchased: 49 @ 305.00pValue: £149.45Lsl Property Services (LSL)Director name: Crabb,IanAmount purchased: 49 @ 305.00pValue: £149.45Henderson Group (HGG)Director name: Wagstaff ,Philip Amount purchased: 47 @ 267.76pValue: £125.85Top Director SellsTribal Group (TRB)Director name: Bowles,IanAmount sold: 909,597 @ 53.50pValue: £486,634.42Caledonia Investments (CLDN)Director name: Cayzer-Colvin,Jamie M BAmount sold: 15,972 @ 2,393.00pValue: £382,209.96Caledonia Investments (CLDN)Director name: Wyatt,WilliamAmount sold: 12,547 @ 2,393.00pValue: £300,249.71Caledonia Investments (CLDN)Director name: King ,Stephen Amount sold: 8,904 @ 2,393.00pValue: £213,072.72Hogg Robinson Group (HRG)Director name: Brindle,WilliamAmount sold: 128,947 @ 70.79pValue: £91,282.09Hogg Robinson Group (HRG)Director name: Radcliffe,DavidAmount sold: 116,604 @ 70.79pValue: £82,544.44Berendsen (BRSN)Director name: Wood,Andrew RAmount sold: 5,000 @ 1,219.00pValue: £60,950.00Hogg Robinson Group (HRG)Director name: Ruffles,KevinAmount sold: 74,827 @ 70.79pValue: £52,970.33Hogg Robinson Group (HRG)Director name: Maher ,Michele Amount sold: 22,126 @ 70.79pValue: £15,663.08
