Mainland stocks on Monday fell the most in a week, led by energy and industrial shares, after the benchmark equity gauge posted three straight weeks of gains.

The Shanghai Composite Index slipped 0.4 percent at the close, the biggest drop since July 8. Yanzhou Coal Mining Co declined for a fourth day to pace losses for a measure of energy companies. China Vanke Co slumped to its lowest level since Dec 1 in Shenzhen as developers retreated after data showing slowing home-price gains.

The Shanghai gauge's 14-day relative-strength index last week crossed the threshold of 70, which some investors see as a signal that a rally is about to reverse. China's economy expanded more than expected in the second quarter, according to official data released on Friday, while monthly aggregate financing, retail sales and industrial output also beat expectations.
