(Yicai Global) Feb. 14 -- China's stock markets were a jumble during the morning session.
 

Investors adopted a wait-and-see approach as a new round of high-level China-US trade talks kicked off in Beijing this morning.
 

They  are also chary as they await the newest economic data to validate their  recent optimism about the businesses of the listed companies they have bet so heavily on of late.
 

The Shanghai Composite Index was down 0.32 percent to 2,712.43 points at the lunch bell. The Shenzhen Component Index rose 0.06 percent to 8,176.31 points, while the ChiNext Price Index of Shenzhen's growth companies inched up 0.03 percent to 1,357.26 points.
 

The three major indexes have been in a jovial mood recently, with the Shanghai Composite Index climbing 5.6 percent, the Shenzhen Component Index gaining 9.4 percent in the past five trading days, and the tech-centric ChiNext Price Index grabbing a 10.6 percent gain in the past four trading days.
 

Chinese and US officials are trying to hammer out a trade compromise before higher tariffs on both countries' exports activate on March 2.
 

Markets will thus remain on tenterhooks until the outcome of these discussions is forthcoming tomorrow.
