(ShareCast News) - Premier Farnell is in a bit of a mess at the moment, according to The Times' Tempus, after a 13.7% fall in interim pre-tax profits, and a warning second half operating profits could be lower than forecasts.Tempus said the stock is a good indicator of global economic trends, but it's also vulnerable to small variations in revenues and margins. With a margin of 35.2% and the stock down 2.2 basis points, it says that those willing to take a risk might consider getting in, but reckons investors should avoid it for now and wait for more news.With the market looking at the first set of numbers, Kier Group's share price dropped 68p to 1,408p. However there are good future growth projections, with shares offering a forward yield of 4.6 per cent on good projections.Tempus believed it's a stock to buy long term, as the fall in price looks a bit overdone and the company has some achievable plans.
