- Investment management firms disappoint- Hard times on the High Street- Phlegmatic response to Fitch's threat to cut UK's AAA ratingAfter a brief sojourn in positive territory during the morning session, the top share index returned to the region where it spent most of the day, bumping along just below last night's close.The decision by ratings agency Fitch to revise the outlook on the United Kingdom's triple-A rating to "negative" from "stable" was largely met with a figurative shrug of the shoulders. The agency said that the change reflects the "very limited" fiscal space to absorb further adverse economic shocks in light of such elevated debt levels and a potentially weaker than currently forecast economic recovery. Fitch notes that the UK's structural deficit is second only to that of the US and that its debt level is "significantly above" the 'AAA' median, although the agency does judge the government's fiscal consolidation plans to be "credible". Blood on the High StreetBritain's leading supermarket chain, Tesco, has long been regarded as one of Britain's world-class operators but it is increasingly looking like a company in turmoil as this morning it was confirmed that Richard Brasher, the head of Tesco's UK operations, is to quit the board.Chief Executive Officer, Philip Clarke is taking a much greater interest in the UK business since the supermarket group's recent profit warning, and no one likes working with the boss constantly looking over your shoulder. As Panmure Gordon put it, there can only be one captain on the bridge, so Brasher is walking the plank.The supermarket firm is in better shape than Home Retail Group, the owner of the Argos and Homebase brands. Indeed, some argue that Tesco is largely the cause of the problems at Argos, which is struggling to hold on to market share as Tesco Direct encroaches on its market.Like-for-like (LFL) sales at Argos chain have taken another tumble in 2012. The group said Argos's LFL sales in the eight weeks to February 25th were down 8.5% year-on-year (YOY). The Homebase part of the business fared a little better, but still saw LFL sales down 6.5% on a YOY basis.Another company struggling with tough economic conditions is commercial vehicle hire specialist Northgate which said that profits for the current financial year are likely to be at the lower end of market expectations. The group is seeking to address declining vehicle utilisation levels but tough economic conditions in its main markets of the UK and Spain are not helping matters.Investment management firms struggleStrategic partners reshaping their insurance books withdrew billions of euros of funds from the care of F&C Asset Management (FCAM) in 2011. Assets under management at the year's end were £100.1bn, down from £105.8bn at the same point in 2010. Net outflows totalled £7.2bn, so the underlying performance of the portfolio was positive, but the shares still tanked. Sector peer Ashmore was also on the slide.Witan Investment Trust was unchanged despite admitting that its 2011 performance substantially lagged that of its benchmark index. Net asset value per ordinary share on a debt at par value fell 11.6% from 584.4p to 516.9p, while on a fair value basis it dropped 12.9% from 578.1p to 503.7p.

Revenue fell 25.3% from £58.5m in 2010 to £43.7m in 2011, while profit before tax dropped by 9% from £6.6m to £6.0m. te sharp differential in the rats of decline is largely down to a sharp fall in performance related pay.Footsie movers and shakersPharmaceuticals firm Shire has withdrawn its Biologics Licence Application for its enzyme replacement product REPLAGAL with the US Food and Drug Administration (FDA).
