FTSE 100 movers: Ryanair profit warning drags fellow aviation stocks lower

Shares in aviation companies easyJet and IAG were all heading south after Ryanair issued a warning on annual profits after its shares plunged in response.Europe's biggest low-cost air carrier said in a trading update it expected full-year net profit to be near the bottom of its earlier guidance of €570-600m and that it could miss the range altogether.Ryanair blamed competition, economic gloom in Europe and the weaker pound against the euro for lower prices and yields - fare per passenger - for September, October and November.TUI Travel, Resolution and BHP Billiton were also heavy fallers after going ex-dividend, meaning that from today new investors won't be able to get their hands on their latest dividend payments. Others that went ex-dividend on the blue-chip index include Admiral, Aggreko, ARM Holdings, IMI, Land Securities, Serco Group and Shire.Meanwhile, Johnson Matthey was a high riser after JPMorgan Cazenove raised its target price from 2,600p to 2,800p. Vodafone was a strong riser, boosted in part by The Times's Tempus, which said it is not the time to hang up on the group which earlier this week agreed to sell its 45% stake in US outfit Verizon Wireless to Verizon Communications in a transaction valued at $130bn (£84bn) in cash and shares.FTSE 100 - RisersVodafone Group (VOD) 205.45p +1.46%Petrofac Ltd.
