Adam Cheng
The Ting Hai effect, also known as the Adam Cheng effect, is a stock market phenomenon in which there is a sudden and unexplained drop in the stock market whenever a film or a television series starring Hong Kong actor Adam Cheng is released. It still remains as a popular topic among stock brokers, years after the television drama "The Greed of Man" was broadcast in Hong Kong in late 1992. The effect is named after Ting Hai, the primary antagonist in the drama, who was portrayed by Cheng.
