Junior oiler Lekoil Limited (LON:LEK) was the major story on AIM this week with its value dropping by around two-thirds after falling victim to con artists posing as the Qatar Investment Authority (QIA).
Shares in the firm were suspended on Monday after the ‘actual’ QIA contacted Lekoil to question the validity of a £138mln (US$184mln) loan supposedly agreed to finance the firm’s drilling activities on the Ogo field in Nigeria.
Lekoil then issued a statement saying the deal had in fact been made with individuals posing as the QIA in a “complex façade” that had involved the company paying the scammers £460,000 (US$600,000) in supposed legal and arrangement fees.
While Lekoil said its losses would be limited to this initial sum, the shares quickly plunged following its return to AIM on Tuesday and at the end of the week were down 66% at 3.2p.
Turning to the wider market, the AIM All-Share was up 1% at 971 during the week, while the FTSE 100 was 0.7% higher at 7,638.
Digital media firm GlobalData PLC (LON:DATA) was hit when Sally Johnson, deputy finance chief of Pearson, said she would be staying on at the publishing giant to replace outgoing CFO Coram Williams. This sent the stock down 10% to 1,265p.
Johnson was due to become the CFO of GlobalData in the first quarter of this year.
Revenues in the seven weeks to 4 January slumped 9.3% with footfall in UK stores and concessions down by 7%. The shares followed suit over the week and sank 22% to 15p.
It was a similar story for toymaker Character Group PLC (LON:CCT), which fell 19% to 330p as “challenging” Christmas trading hit sales and resulted in profit forecasts falling below market expectations.
A profit warning piled the pressure on hydraulics and pneumatic components maker Flowtech Fluidpower PLC (LON:FLO), which tumbled 18% to 104p. Its earnings are forecast to be around £1.9mln lower than last year after a tough fourth quarter.
