(ShareCast News) - Clarkson´s chairman, James Hughes-Hallett, picked up a batch of shares of the battered shipbroker a day after it issued a profit warning.On 4 July, Clarkson said profits in 2016 would be "materially lower" than in full-year 2015 as a result of lower freight rates, quiet capital markets and weak investor confidence.In its latest trading update, the company referenced the sharp drop seen in the Baltic Dry Index during the first quarter, when it tested its all-time lows.Hughes-Hallett bought 1,500 shares at an individual price of 1,800p for a total consideration of £27,000.That same day and the next Peter Backhouse, a non-executive director, followed suit, picking up 2,500 shares for £42,778.Shares in Clarkson closed 6.57% weaker on Wednesday at 1,677p, in the process setting a new 52-week low, giving the company a market value of £507m.Top Director BuysValue And Income Trust (VIN)Director name: Oakeshott,Matthew AAmount purchased: 60,000 @ 234.00pValue: £140,399.99Paragon Group Of Companies (PAG)Director name: Dench,RobertAmount purchased: 43,278 @ 231.06pValue: £99,998.15Witan Inv Trust (WTAN)Director name: Bell,Andrew L CAmount purchased: 10,000 @ 746.00pValue: £74,600.00Newriver Retail Limited (NRR)Director name: Lockhart,DavidAmount purchased: 25,000 @ 287.50pValue: £71,875.00Henderson International Income Trust (HINT)Director name: Hills,RichardAmount purchased: 33,206 @ 126.84pValue: £42,118.49Intelligent Energy Holdings (IEH)Director name: Guidotti,FlavioAmount purchased: 412,500 @ 8.90pValue: £36,712.50Ricardo (RCDO)Director name: Morgan,TerryAmount purchased: 5,000 @ 698.00pValue: £34,900.00Daily Mail And General Trust A (non.v) (DMGT)Director name: Zwillenberg,PaulAmount purchased: 5,000 @ 594.84pValue: £29,742.21Clarkson (CKN)Director name: Backhouse,PeterAmount purchased: 1,500 @ 1,863.82pValue: £27,957.34Clarkson (CKN)Director name: Hughes-Hallett,JamesAmount purchased: 1,500 @ 1,800.00pValue: £27,000.00Dragon-ukrainian Properties & Development (DUPD)Director name: Fiala,TomasAmount purchased: 210,258 @ 12.69pValue: £26,679.64Balfour Beatty (BBY)Director name: Billingham,Stephen RAmount purchased: 12,165 @ 204.38pValue: £24,863.43Norcon (NCON)Director name: Aanensen,Arne Dag Amount purchased: 115,612 @ 19.00pValue: £21,966.28Norcon (NCON)Director name: Tostrup,Trond HelgeAmount purchased: 115,612 @ 19.00pValue: £21,966.28Norcon (NCON)Director name: Vik,GauteAmount purchased: 115,612 @ 19.00pValue: £21,966.28Norcon (NCON)Director name: Longem,Jørn ArveAmount purchased: 115,612 @ 19.00pValue: £21,966.28Lowland Investment Co (LWI)Director name: Troughton,PeterAmount purchased: 1,244 @ 1,217.50pValue: £15,145.70Be Heard Group (BHRD)Director name: Parekh,RakhiAmount purchased: 320,754 @ 3.18pValue: £10,199.98Lekoil Ltd (di) (LEK)Director name: Eckersley,Gregory Amount purchased: 55,000 @ 18.50pValue: £10,175.00Clarkson (CKN)Director name: Backhouse,PeterAmount purchased: 315 @ 1,800.00pValue: £5,670.00Urals Energy Public Co Ltd.
