SHANGHAI, Nov 6 (Reuters) - China's stocks surged for the third consecutive session on Friday as investors continued bets on blue chip companies, notably securities brokerages.

The CSI300 index closed the week up by 7.3 percent, its best week since early June. The composite index rose 6.1 percent in the week.
The mainland stock indexes are up by more than 25 percent from the troughs they hit during the August stock crash, and the rally this week has driven trading volumes to a three-month high.
Profit-taking among blue-chip companies seen earlier in the session was quickly reversed in the afternoon, with the financial service index up by 3.2 percent.
A total of 14 securities firms including Everbright , Orient Securities and CITIC Securities have hit their upward daily limit of 10 percent and the rest surged more than 7 percent.
