(Yicai Global) Sept. 12 -- Italian luxury fashion brand Prada SpA [HKG:1913] saw first-half revenues fall 5.7 percent on the year due to a decline in the number of tourists going to Europe, thought to be related to the appreciation of the Euro.

Sales at the firm's store on New York's Fifth Avenue were also affected by people protesting against US President Donald Trump, Patrizio Bertelli, chief executive, said in a conference call with analysts.

Net profit for the first six months fell 18 percent compared with last year to EUR 115.70 million (USD138.5 million), short of the analysts' expectations. The company's H-share price fell 13.95 percent to HKD 24.05 (USD3.08) on Sept. 11 after the news.

Falling demand for products among Asian consumers may affect Prada more than other companies, as half of its revenue comes from Asia. It closed down 13 of its stores in the first six months and plans to expand its e-commerce website to China and other markets by the end of the year.
