Analysts wonder if 500.com is still a good bet after share price falls 5%

The United States-listed 500.com Ltd, an online sports lottery service provider in China, saw its share price drop nearly 5 percent after it reported on Monday a profit surge of 436 percent year-on-year in the second quarter, mainly boosted by the 2014 FIFA World Cup fever.

Despite the fact that 500.com's performance beat analysts' expectations, concern remained that the Shenzhen-based company may lose its charm among football fans after the once-every-four-years event.

However, analysts pointed out that China's online lottery market is still largely untapped.
