The Market Vectors Gaming ETF (NYSEArca: BJKhas lost about 10% over the past three months as the gaming industry has weakened. Big gaming centers such as Macau and Las Vegas have seen revenue tumble over the past quarter.

Still, the gaming ETF has managed to pare the loss in August with a slight recovery.

Grant Govertsen, analyst at Macau based Union Gaming, expects gaming revenues to see low-single-digit growth in August before bouncing back to double digits in September. “All in, we are expecting third-quarter gross gaming revenue growth in the mid-single-digits. Looking further out, we expect full-year 2012 GGR growth to reach the teens,” said Grant Govertsen. [New Benchmarks For Coal, Gaming ETFs]
