Southeast Asia Stock Market Summary, 17-21 July 2017

Each week, we provide an overview of the percent returns of the primary indices in Southeast Asia and their currency appreciation or depreciation relative to the US Dollar.  We provide this information below.  We also capture this information, as well as the trailing four and twelve week movements, and plot the data in charts, which you can find on the “index charts” and “currency charts” pages.


During the week of 17 July, four indices in Southeast Asia advanced, while five declined. The Philippines Stock Exchange index (PSEi) led all gains, rising 1.32%. Of note, Myanmar’s Myanpix Index (YSX) increased 1.15% during the week and has gained 6.96% since 3 July, bringing its trailing four week return to 4.05%, the highest of the nine indices.

The Vietnam All Index (FTFVAS) declined the most over the week, falling 3.32% and reversing its trailing four week return to -2.57%, which is the greatest decline of the nine indices.
