ZURICH, April 26 (Reuters) - German financial watchdog BaFin warned investors on Thursday about emails recommending the purchase of shares in Swiss social network operator ASMALLWORLD , saying they may contain misleading information or conceal conflicts of interests.
BaFin has started an investigation into suspicion of market manipulation of the shares, which are listed in Germany as well as Switzerland. "At the Frankfurt am Main trading venue (including Xetra), price determination was suspended until further notice with effect from 3 April 2018," it said.
Shares in Switzerland, which made their debut in March, were last down 19.7 percent at 17.75 Swiss francs.
