BUZZ-Jupiter Fund Management: falls on rising costs and margin threat

** Jupiter Fund Management falls 2.4 pct despite a headline beat of earnings, with brokers citing higher costs and pressure on margins as negative

** FY profits up 2.9 pct, better than expected

** Liberum points to fixed costs being £7 mln p.a. higher - broker 10 pct below consensus and says downgrades set to follow

** Panmure double-downgrades to "sell" from "buy", says co's c. 50 pct operating margin likely to come under pressure, especially the co's Merlin multi-manager funds, accounting for around 40 pct of profits

** Stock fell as much as 6.8 pct in early trade before recovering, but still among top fallers on FTSE 250
