<strong>INMARSAT</strong><br />Goldman Sachs said that Inmarsat&rsquo;s recent underperformance has created an opportunity to invest in the shares. It believes there is 38 per cent potential upside to its 712p 12-month price target and has now added the stock as an &ldquo;outperform&rdquo; to its UK relative value list.<br /><br /><strong>DSG INTERNATIONAL</strong><br />DSGI&rsquo;s good sales figures deserved a better share price response, according to Deutsche Bank, which has increased its target price from 23p to 30p. Better Nordic and Italian sales led the broker to increase its full year sales forecasts from &pound;40m to &pound;48m, but remain a &ldquo;hold&rdquo; on the stock.<br /><br /><strong>MARKS &amp; SPENCER</strong><br />Bernstein took an &ldquo;educated leap of faith&rdquo; and upgraded Marks &amp; Spencer to &ldquo;outperform&rdquo; with a price target of 410p. The broker said that three factors will support the stock: positive trading newsflow, a clearer sense of the benefits of its new ad campaign, and new leadership taking the helm.
