The short version
Harbor Osmosis Emerging Markets Resource Efficient ETF (EFFE) is an actively managed fund. It holds about 90 large and mid-sized emerging-market companies, chosen by a computer model that favors firms that emit less carbon, use less water and create less waste than their sector peers. Its 0.69% expense ratio is about three times the 0.23% average of similar funds. Its record is short, since it launched in December 2024.

How it works
EFFE is actively managed, not an index fund. Its subadvisor, Osmosis Investment Management US LLC, scores companies on their publicly reported carbon emissions, water use and waste. Each company is compared only with others in its own sector, so an automaker is ranked against other automakers. Osmosis believes these Resource Efficiency Scores help predict which companies will beat the MSCI Emerging Markets Index, the fund's benchmark. The prospectus says this outcome is not guaranteed.
An optimizer, a program that balances several goals at once, sets the holdings and their weights. It leans toward high scorers while keeping country, sector and factor weights close to the benchmark. Factors are traits such as quality, volatility, debt levels and earnings yield. At least 80% of assets must go to benchmark companies whose scores rank in the top three-fifths of their sector. Financial companies are not scored. They are added to keep the portfolio's overall balance. Up to 20% can go to other holdings to stay close to the benchmark. Companies without enough data to score are left out.
The fund usually holds 70 to 90 stocks and rebalances monthly. It excludes tobacco companies, makers of cluster munitions and anti-personnel mines, and companies that breach the United Nations Global Compact's principles. Osmosis follows the model's buy and sell output except in very limited circumstances. The prospectus reports portfolio turnover of 123%. Trading costs from that turnover are not included in the expense ratio.
What it really costs
- EFFE charges 0.69% a year, versus an average of 0.23% for the similar funds below (4th of 4, cheapest first).
- Using the prospectus's standard example, $10,000 invested would cost about $70 in the first year and $859 over 10 years (assuming a 5% annual return).
| Cost of $10,000 (SEC example) | 1 yr | 3 yrs | 5 yrs | 10 yrs |
|---|---|---|---|---|
| EFFE | $70 | $221 | $384 | $859 |
In a retirement portfolio
It is a concentrated, higher-cost emerging-market stock fund with sharp price swings and less than two years of history, so it fits better as a small add-on than as a foundation.
EFFE could add emerging-market stocks with an environmental tilt to a portfolio built mainly on broader funds. It launched on December 17, 2024, so it has no record from the 2008, 2020 or 2022 downturns. Its only full calendar year, 2025, returned 22.12%. Its deepest drop was 16.3%, from June 2 to July 29, 2026, and it had not regained that peak as of October 27, 2026. Volatility, a measure of how much the price swings, was 25.9% over the year to that date. Anyone who may need to sell in a bad year could end up selling after a drop like that. The trailing 12-month yield was 4.22% as of October 27, 2026, paid once a year. In the SEC's standard example, $10,000 invested costs $70 in the first year. Past results don't predict the future, and a plan should look at the whole portfolio, not one fund.
Who it may suit — and who should look elsewhere
May suit
- Investors who want emerging-market stocks tilted toward companies with lower carbon, water and waste, with tobacco and controversial weapons excluded.
- Those comfortable with a rules-driven, actively managed approach that aims to beat the MSCI Emerging Markets Index but may fall short.
- People seeking a small, higher-risk slice who accept heavy weights in Taiwan (25%) and South Korea (22%) as of July 31, 2026.
Look elsewhere if
- Cost-focused investors: the 0.69% expense ratio compares with 0.26% for ESGE, 0.32% for NTSE and 0.10% for VSGX.
- Anyone who wants a long track record. The fund launched in December 2024 and has never been through a major bear market.
- Retirees who need steady income. The 4.22% trailing yield as of October 27, 2026, is paid only once a year.

Is EFFE an index fund?
No. EFFE is actively managed. Its subadvisor, Osmosis Investment Management US LLC, uses its own Resource Efficiency Scores. These rate companies on carbon emissions, water use and waste compared with sector peers. An optimizer then picks about 70 to 90 stocks and sets their weights, keeping country and sector exposure close to the MSCI Emerging Markets Index. That index is a benchmark the fund tries to beat, not one it copies. The portfolio is rebalanced monthly.
What are EFFE's top holdings?
As of July 31, 2026, the five largest holdings were Wistron (4.0%), Wiwynn (3.8%), Kia (3.7%), Taiwan Semiconductor Manufacturing (3.6%) and Lenovo (3.6%). The fund held 90 stocks, and the top 10 made up 33.6% of assets. By country, Taiwan was 25.2%, South Korea 22.3%, China 14.4% and India 11.7%. Net assets were about $135.7 million.
What's the difference between EFFE and ESGE?
Both own emerging-market stocks with an environmental or ESG angle, but they overlap by only 17%. The iShares ESG Aware MSCI EM ETF (ESGE) charges 0.26% a year, compared with 0.69% for EFFE. ESGE also had about $6.9 billion in assets, against EFFE's $135.7 million. Over the year to October 27, 2026, ESGE returned 15.2% and EFFE returned 8.7%. EFFE uses its own resource-efficiency scores to pick about 90 stocks.
Does EFFE pay dividends?
Yes, but only once a year. Over the 12 months to October 27, 2026, it paid $1.08 per share, a trailing yield of 4.22%. A single yearly payment means income arrives in one lump rather than monthly or quarterly. Payments from emerging-market companies can also change from year to year with their profits and with currency moves against the US dollar.
How has EFFE performed since launch?
EFFE returned 22.12% in 2025, its first full calendar year, according to its prospectus. Its share price was up 10.8% for 2026 through October 27, 2026, and up 17.3% in total since its December 2024 launch. Over the year to October 27, 2026, its 8.7% return ranked last among the four similar funds compared here. Its deepest drop was 16.3%, between June and July 2026.
