Six of the concerts originally scheduled have been sold out, another three are planned.
In its response after the market closed, the company says that response to Cheung's concert has been "overwhelming".
"Other than this, the company is also not aware of any other possible explanation for the unusual price and volume movements in the trading activity of the company’s shares," adds UnUsUal.
