The coronavirus outbreak has continued to spook markets as the London Stock Exchange dropped to a new 13-month low and traders warned that the virus could lead to "anaemic global growth".

The FTSE 100 leading index of the UK's biggest listed companies has now fallen more than 7% in the past four days, and fell 2.6% in early trading on Thursday, shedding 177 points to 7,436.

Companies around the world are reporting how the outbreak was hitting profits and trading.

On the markets, it was airlines and holiday firms that were hardest hit, with shares in Tui, easyJet and British Airways owner IAG all down heavily.

EasyJet has suffered harder than most, with shares collapsing 26% in a week, as holidaymakers postpone trips and businesses reduce travelling.

Some traders had expected stock markets needed a "correction" because they had been trading at record levels in recent months. But some were questioning whether this was more than a correction.

Ipek Ozkardeskaya, of Swissquote bank, said: "The slide we are seeing right now is not the correction of the recent stock rally, but the market's understanding that the coronavirus outbreak would translate into significantly lower earnings and an anaemic global growth.

"If we add the fact that the crisis has only started outside China into the mix, there is a meaningful shift in stock valuations."

Reckitt Benckiser revealed sales of cleaning and hygiene products have increased.

Aston Martin Lagonda has warned that the coronavirus outbreak could hit demand and supply in its key Chinese market as the troubled luxury car maker posted widening annual losses.

China was its fastest-growing market last year and accounted for 9% of total wholesales.

The group gave assurances that it has secured supply until at least the end of March and had not yet seen any impact on production.

Full-year results showed pre-tax losses widened to £104.3 million in 2019, against losses of £68.2 million the previous year, while the group also confirmed plans for a £500 million investor cash call as it seeks to secures its future.

Aston Martin said sports car wholesales are expected to be "materially lower" in 2020, which will affect first-half sales.

It added that underlying earnings will be "almost entirely" weighted to the final six months due to deliveries of its DBX and Specials.

Standard Chartered has warned it is likely to grow below its target range as coronavirus continues to drag on the Asian economy.

The banking services group said it now expects income growth to be less than its medium-term 5% to 7% target range, because of the outbreak.

It also cited lower interest rates, and weaker economies both globally and in Hong Kong, a vital market, to explain the lower expectations.

At least 2,800 people are thought to have died from the disease around the world, since the outbreak started in earnest earlier this year.

The vast majority of these have been in mainland China, but it has also spread to other countries in the region, as well as Europe and the Middle East.

It has added to an already tough 12 months for many businesses operating out of parts of Asia.

Standard Chartered also had to deal with a trade war between the US and China, and the political unrest that gripped Hong Kong.

"There were several reminders in 2019 as well as in the first weeks of this year of the importance of the progress we have made improving our resilience to external shocks," said chairman Jose Vinals.

The warnings came as Standard Chartered revealed pre-tax profit was up 46% to $3.7 billion (£2.9 billion) in 2019. Operating income grew 4% to $15.4 billion (£11.9 billion).

On an underlying basis, pre-tax profit was up 8% to $4.2 billion (£3.3 billion), on operating income of $15.3 billion (£11.8 billion).

Chief executive Bill Winters said: "Discipline on the things we control and a sharp focus on where we are differentiated enabled us to grow underlying profit 8% and improve earnings per share by 23% in 2019, despite an increasingly challenging external environment.

"We are in the right markets guided by the right strategy and united through our purpose to drive commerce and prosperity. I am confident that we have set ourselves up for lasting success."
