The telecom equipment firm was plunged into crisis after it failed to win a part in BT's £10bn network revamp. Its share price fell nearly 40 per cent in one day, and the firm faces 2,000 redundancies.
B&Q suffered the worst fall in the table, dropping 1,048 places into the bottom five. Permira and Apax Partners are reported to be interested in bidding for the DIY chain, which issued a profit warning.
The chain's owner, Kingfisher, also dropped into the bottom placings.
At the top end, Airbus leapt into third, up 26 places after its A380 completed its maiden flight last week to critical acclaim from the press.
Interestingly, rival Boeing jumped 15 places to creep into the top five despite reporting a 14 per cent drop in first-quarter profits. It gained positive coverage on the back of announcing robust sales of its 787 Dreamliner to Air Canada and Air India.
Asda narrowly maintained its hold on the top position, beating Tesco by two points. Sainsbury's jumped five places to fourth after securing school dinners campaigner and TV chef Jamie Oliver for another year as its spokesman.
