The Vanguard FTSE Emerging Markets ETF (NYSEArca: VWO) is up 2.1% in the past month. Relative to a 7.1% year-to-date, VWO’s one-month performance is not too shabby. Since September 10, VWO  has pulled in $505.5 million in assets.

Again, that is pretty good compared to the $4.2 billion the fund has lost this year. VWO is, however, still the largest emerging markets ETF by assets. VWO’s scant 0.18% annual expense ratio means the fund is cheaper than 89% of rival products, according to Vanguard.

Those are not the most important numbers VWO has to contend with at the moment. VWO closed at $42.21 Wednesday, up 0.72% on volume that was slightly above average. To bring buyers off the sidelines, VWO might need to close above $43, something it has not done since May. [Return to me: Cash Flowing Back to EM ETFs]

However, $43 could be seen as more of psychological resistance. Firmer resistance for VWO is just beyond that point.

“I do see a congestion area between $44 and $45 which will present some resistance. It may take further momentum to move through that area,” said David Chojnacki, president of Street One Technical Analysis, LLC in an email exchange with ETF Trends.

VWO has not closed above $45 since January. The ETF’s 52-week high is in the $45.50 area.

“With VWO recently moving above it 200d-SMA($41.11),it appears to be developing longer term strength to the current move.  Short term it is above key short term averages and just recently saw Its MACD cross above signal, which is positive,” said Chojnacki.
