Article preview: In our latest monthly investment update for May 2019, we look at how the investment markets, the global economy and commodity prices are performing. The FTSE 100 index of leading UK company shares finished closed at the end of April at 7,418.22 points, experiencing yet another positive month, rising 139.03 points or 1.91% during the month. European markets experienced a fourth consecutive month of gains, with the STOXX 600 index up by 3.2% in April, representing its longest winning gain streak since May 2017. Markets have been driving higher by a combination of rising oil prices and positive economic data in the eurozone. These factors helped to buoy investor sentiment, despite weaker than anticipated factory data from China, which cast doubts over prospects of continued global economic growth.
