The current 28 holdings place a heavy weighting on energy, materials, and financial names, most of which have small or middling market caps. The fund is expected to be in high demand as Vietnamese shares have been among the best performing in the world this year. The benchmark VN Index - which is broader than the one VNM tracks - is up 61% this year. Investors will pay a premium for access, however, as the fund carries a .99% expense ratio. By contrast, European investors pay only .85% for the db-x trackers FTSE Vietnam (XFVT).
