Wednesday preview: Imagination Tech, SuperGroup, The Fed...

First-half figures from FTSE 250 peers Imagination Tech and SuperGroup are on the calendar for Wednesday morning.Jefferies is expecting Imagination Tech, the multimedia, communications and embedded processor technology company, to report sales of £62.9m up from £56.3m the year before."We see in line progress through 1H13 with volumes growing, design wins coming to production but a bit of weakness in the average royalty rate and growing opex all flagged before," said analyst Lee Simpson on November 29th in a research report.As for trendy fashion retailer SuperGroup, all eyes will be on the bottom line with the firm already having reported sales figures in its second-quarter trading update.Total group sales for the half increased by 16.2% to £158.2m, helped by a strong second quarter (+20.3%)."Whilst mindful of a competitive Christmas trading season ahead, the group is on track to deliver a profit figure in-line with the market's expectations for the full year," the firm said.In other news, the Federal Reserve (Fed) is expected to take its expansive monetary policy to new heights on Wednesday when it concludes its last scheduled policy-setting meeting of 2012 and in that manner potentially offset the upcoming 'fiscal cliff'. Analysts are expecting the Fed to announce a new long-term bond purchase programme valued at $45bn per month as "Operation Twist" comes to an end. Some 48 out of 49 analysts surveyed by Bloomberg are expecting new stimulus on top of the $40bn monthly mortgage-bond buying programme announced in September, commonly referred to as QE3 (third round of quantitative easing).
