South Korea's Hyundai Heavy Industries group (HHI) has surprised equities analysts by reporting a profitable first quarter.

HHI reported a KRW 2.8bn ($2.4m) net profit for the first three months of 2019 — a big comeback compared to the loss of KRW 222.9bn recorded in the previous quarter.

This profit was somewhat unexpected given that the average analyst estimate predicted a loss of KRW 53.46bn
