Mainland stock markets saw mixed performance on Tuesday after fluctuating during the day.

The Shanghai Composite Index inched up by 0.34 percent or 13.85 points to 4,135.57 points on Tuesday, reaching a new seven-year high. But the Shenzhen Component Index fell by 0.76 percent or 107.04 points to 14,042.46 points.

The CSI 300 Index, which tracks the 300 biggest companies on the Shanghai and Shenzhen bourses, rose by 0.39 percent to 4,438.18 points on Tuesday.

Total transactions on the two bourses reached 1.46 trillion yuan ($232.9 billion), exceeding 1 trillion yuan for an 11th consecutive trading day.

Shares in transportation, electricity and infrastructure companies surged on Tuesday while insurers, banks, oil and media stocks weighed down on the markets.

Stock brokerages had fallen in the previous trading session after the country began allowing investors to open multiple accounts, but they recovered on Tuesday, rising 0.86 percent on average. Shanxi Securities Co soared by the daily limit of 10 percent to 20.77 yuan and Soochow Securities Co surged by 7.32 percent to 29.19 yuan.

Allowing multiple accounts for investors is likely to increase competition among brokerages but it will benefit companies that offer good services and competitive fees, analysts said.

Insurance companies underperformed the markets on Tuesday, with China Life Insurance Co and New China Life Insurance Co down by 3.42 percent and 3.27 percent, respectively.

ChiNext, the country's NASDAQ-style board for high-tech and emerging start-ups, declined by 0.73 percent or 18.93 points to 2,558.85 points on Tuesday.

In Hong Kong, the Hang Seng Index ended an eight-day rising streak on Tuesday. It had reached its highest level in more than seven years on Monday, but the index fell by 1.62 percent to 27,561.49 points on Tuesday.
