Oct 24 (Reuters) - United Parcel Service (UPS.N) investors want to see this week how the delivery giant is managing through the bursting e-commerce delivery bubble better than rival FedEx (FDX.N). Shares in UPS are down roughly 20% so far this year, versus the 40% decline in FedEx stock. At the same time, the UPS sales team has been working to drum up new business. Lego, the $7.3 billion Danish maker of colorful plastic bricks used to build everything from UPS delivery trucks to Hogwarts Castle of Harry Potter fame, switched from FedEx to UPS, according to the sources, who asked not to be identified. Global air and ocean import cargo volumes, a gauge of demand for logistics companies like UPS and FedEx, are slumping.
