The Shanghai Composite Index rallied for a fifth day to a seven-year high as investors sought financial companies and other underperformers this year, while rotating out of overvalued, small-company stocks.

The Shanghai Composite climbed 1.5 percent to 4,729.12 at 9:51 a.m. It advanced 8.1 percent last week, the biggest gain since the week ended Dec. 5, amid speculation the government may escalate measures to stimulate the economy. The CSI 300 Index rose 1.4 percent. Hong Kong’s market is closed Monday for a public holiday. The ChiNext slumped 3.3 percent, heading for the biggest drop since April 15.

The China Securities Regulatory Commission will target listed companies’ information disclosure and abnormal trading activities in an effort to clamp down on market manipulation, according to a statement posted on its microblog on Friday.
