Goldman Sachs Group said in a report on Monday that hedge funds focusing on the Japanese market are facing the largest single-day performance loss in Goldman's history, following the global stock market plunge triggered by weak US employment data and the Bank of Japan's rate hike last week. As of the Asian market close, performance of hedge fund managers focusing on the Japanese market has dropped by 7.6% over the past three trading days, with a 3.7% decline on Monday marking the largest single-day performance drop ever recorded by Goldman, wiping out the year-to-date gains of these hedge funds over the past three trading days.
