One to watch: Amerisur Resources

The company plans to grow production from 550bbl/d to 5,000bbl/d by the end of the year from an existing oil field onshore southern Colombia. In addition, recently acquired 3D seismic on the key Platanillo Block has identified almost 100mmbbls of prospective resources, highlighting the potential for long-term production growth. We would recommend buying the stock ahead of the start of a four-to-six well drilling programme starting in July once environmental approvals are secured later this month.

Colombia may appear an unlikely location to look for a low-risk investment opportunity. However, the country's security issues have improved markedly and the oil sector has enjoyed a history of fiscal stability with no retrospective tax increases, unlike the UK. In addition, the government in Colombia is focused on growing oil production in the country and views foreign investment as a key part of achieving this goal.

NUMIS's David McCann welcomes an admission from the wealth manager that its 17 per cent margins – vastly lower than its rivals such as Rathbones, which makes 30 per cent – are a problem. Numis figures plans to replace a 30-year-old, labour-intensive investment management system could do the trick.

FEARS that SuperGroup may be over-reaching in its acquisition of a lease on a flagship Regent Street store property from Austin Reed may be overdone, said analysts from Arden Partners, arguing that a recent collapse in shares makes them supercheap for a group with such overseas growth potential.
