(Yicai Global) Jan. 9 -- The Shenzhen Stock Exchange's primary and growth  benchmarks hit 21-month highs today as investors regained confidence in the future  after Middle East tensions ratcheted down when US President Donald Trump shrugged off  Iranian rocket attacks on American military bases in Iraq.

 The Shenzhen component index closed 1.79 percent higher at 10,898.17 at the final bell, while the ChiNext Price Index, which tracks growth enterprises listed in Shenzhen, shot up 2.71 percent to finish off at 1,913.14. The Shanghai Composite Index was up 0.91 percent at 3,094.88.

Tehran "appears to be standing down," Trump said yesterday at the White House, after reporting that the Iranian attack, retaliation for the US killing one of its major generals, did not harm US troops and inflicted only minor damage on facilities.
