According to the data compiled by market tracker FnGuide, combined operating income of 138 listed firms surveyed by brokerage firms stood at 19.97 trillion won (US$16.3 billion) for the April-June period, down 26.7 percent and 19.1 percent, respectively, from three months and one month ago.

Hit by weak demand and production disruption around the globe amid COVID-19 outbreak, companies are suffering a sharp decline in sales and profit.’

The country’s exports plunged 24.3 percent in April from a year earlier, due to the new coronavirus pandemic and falling oil prices, and suffered the first monthly trade deficit since 2012.

Outbound shipments came to $36.9 billion last month, compared with $48.7 billion posted a year earlier, according to the Ministry of Trade, Industry and Energy.

The country suffered a trade deficit of $950 million in April, snapping its 98 straight months of having more exports than imports.

The COVID-19 pandemic has clobbered the global supply chain, with lockdowns and social-distancing drives hindering business activities around the world.

The falling price of oil has also weighed down exports of petrochemical products, some of the country’s key export items.
