Strong investor sentiment has elevated China's benchmark Shanghai Composite Index to a fresh all-time high of 5,724.36 points in Monday's morning session, the first trading day after the weeklong National Day holiday.

The bullish performance, a rise of more than 3 percent from the previous close, came treading on the heels of the rises on neighboring markets during the National Day holiday period that ran from October 1 to 7.

The index started sharply higher at 5,683.31 points, up 131.01 points or 2.36 percent from the previous close, only slightly dipped after profit taking in the first 15 minutes and then moved all the way up to finally stay at 5,718.49 points at morning close.

The rises were driven up by bank shares with the heavyweights such as the Industrial and Commercial Bank of China and the Industrial Bank reporting increases close to the daily rise ceiling of 10 percent.

Many companies that have registered increases in the prices of their H shares during the past week have also reported noticeable advancement with the China COSCO Holdings Company Limited growing by the highest 10.01 percent to 49.57 yuan per share. China life followed with a rise of more than 9 percent.

The share price of CCTIC Securities has broken the 100-yuan level, stimulating the growth of the securities sector.

The newly-listed China Oilfield Service Limited shot up by more than 4 percent after opening lower at 37.58 yuan per share.

Retailing and hotel sectors which saw a business boom during the holiday season found their share prices dipping slightly.

The Component Index on the smaller Shenzhen Stock Exchange continued to pick up on expanded turnover, approaching the day's morning high of 19,374.36 points.
