Jun-ho Cha 6 HOURS AGO ENG The Korean Teachers' Credit Union (KTCU) achieved its highest investment return in 11 years of 10% in 2020, led by substantial gains from domestic equities and from the divestment of Ellie Mae Inc., a US cloud-based platform provider. Last year's return marks its strongest annual result since 2009, amounting to 3.3 trillion won ($2.9 billion) in investment gains for the whole year of 2020, the South Korean retirement fund said on Apr. 2. Domestic equities returned almost 40%, far outstripping the 6.3% from alternative assets. Domestic and overseas stock portfolios outperformed their benchmarks by 8.9 percentage points and 11.6 percentage points, respectively. Among alternatives, its $37.6 million bets on Ellie Mae generated a 67% return, or $153.8 million in proceeds, in just one and a half years. The KTCU had invested in Ellie Mae through a fund of the US-based Thoma Bravo which sold the US software company to the global securities exchange operator Intercontinental Exchange (ICE) for $11 billion last year.
