Continued impacts of coronavirus outbreak
BBC Radio 5 Live
Copyright: Getty ImagesDiageo, French food group Danone, German airline Lufthansa and tech giants Apple and Microsoft have become the latest firms to quantify the immediate impact of Coronavirus outbreak on their businesses.
On Wednesday, oil firm Chevron asked 300 staff based in London's Canary Wharf to work from home after an employee returned from a skiing trip to Italy and reported flu-like symptoms.
The knock-on effect of this was that catering outsourcing firm Compass saw its share price drop dramatically, as investors feared that staff canteens wouldn't be used as much.
"At the moment you've got three different types of [concerns] - you've got Diageo saying demand in China has been hit, you've got companies like Apple and Microsoft saying how supply chains are being affected, and then you've got the airlines and Compass, where investors are wondering what impact it will have on other markets around the world," Russ Mould, investment director at AJ Bell explained to BBC Radio 5 Live's Wake Up to Money programme.
Diageo 'not immune' to global trade policy

Ivan Menezes, chief executive, says the year has started well and it expects operating profit to grow roughly one percentage point ahead of organic net sales.
"This is consistent with what we are targeting over the medium-term. Due to a strong prior year comparable, for the first half we expect organic operating profit growth to be in-line with or slightly behind organic net sales growth. However, we would not be immune from significant changes to global trade policy and continue to monitor this closely."
