Shares in Barclays fell following Tuesday's news of a fall in first-quarter profits, but brokers are advising investors to buy the shares on hopes that its turnaround plan will bear fruit.Barclays is cutting costs and slashing jobs in a shake-up to streamline the bank and has pledged to give more details of its plans on Thursday.

The economy is getting stronger and real wages are picking up which is very supportive," the broker said.Cantor Fitzgerald has slashed its target price for AIM-listed Fastnet Oil & Gas after the company plugged and abandoned one of its wells offshore Morocco."In terms of valuation, we increase our overall risking of Moroccan frontier acreage, especially following Cairns unsuccessful well in December 2013.
