The Chinese CSI 300 Health Care Index suffered a significant drop when trading opened on Monday, but none of the individual stocks decreased by more than 2 percent; however, the sudden decline was due to an internal glitch from the resulting change in the index-calculation system over the weekend.
The Health Care Index dropped by 17% when trading opened on Monday, but later rebounded to normalized pricing by the afternoon, with a thorough correction to take place after closing. Nevertheless, such a rare index glitch is rarely in occurrence, and analysts are unsure of the oncoming effects it may have on ETF trades that experienced momentary misleading prices. The CSI data is used by some to conduct quantitative trading via automatic programs, and such a discrepancy on prices can create problems and losses.
The CSI Index is predominantly listed in Taiwan, Hong Kong, South Korea, and mainland China, and is comprised of of exchange-traded funds based on various healthcare firms. Thus far, the CSI 300 has increased by 10% this year, but has lost 6.2% as a result of the glitch.
