International Business Times reported on May 25 that famous economist Lang Xianping pointed out at the scene of a program recording on the evening of May 24 that there was a striking resemblance between the recent trends in Hong Kong's Hang Seng Index and the US Dow Jones Index. Lang Xianping claimed that the underlying reason was that international big investment banks were "manipulating" the Hang Seng Index, attempting to drive it up before selling short to reap huge profits.
