Corrects name of broker in paragraph 4 to KBC
** Barco BAR.BR shares drop as much as 10% to their lowest since July 2016 after the visualisation technology group missed Q1 sales expectations and warned it may not be able to maintain its FY guidance
** KBC Securities says the Belgian co was hurt by a strong foreign exchange headwind, delayed order conversion and cautious customer decision-making in challenging market conditions
** "Sales were impacted by the ongoing geopolitical uncertainty, mainly in the Americas, while EMEA was more resilient, despite impact in the Middle East," the broker says
** KBC trims its price target to 12 euros from 13.2, sticking to its hold rating
** By 0729 GMT, stock off lows, down 6% at 9.1, bringing YTD fall to almost 23%
