Harbor Capital Advisors, Inc. ("Harbor"), the asset manager that curates a select suite of predominantly actively managed ETFs, mutual funds, and collective investment trusts, celebrates three years since launching the Harbor International Compounders ETF (OSEA).

“We began our partnership with C WorldWide over three years ago, culminating with the launch of OSEA. We are steadfast in our belief there is a critical role in portfolios for international markets exposure and partnering with C WorldWide, a firm that runs a long-term thematic 30-stock concentrated portfolio, has historically provided a framework for long-term compound capital over time,” said Kristof Gleich, President and CIO of Harbor Capital Advisors.

Gleich continued, “We partnered with C WorldWide to help bring a long-term active manager from Copenhagen to intermediaries in the U.S., and we are just getting started. Despite the fact that quality has significantly underperformed broader markets over the past 18 months, or perhaps, because of; I maintain the view that longer-term clients could be positioned for potential rewards."

For long-term oriented advisors seeking attractive opportunities, OSEA may offer a compelling option. Its unique composition of high-performing “compounders,” selected by a world-class team of investors using a disciplined process and supported by enduring themes, seeks to provide exposure to a rigorously researched and focused pipeline of what we believe are some of the best companies in the world – those built to sustain consistent growth levels well into the future.

We believe OSEA makes a good case for compounding. We believe OSEA may appeal to clients seeking long-term exposure to world-class franchises that have historically benefited from secular trends, demonstrated growth potential, and generated cash flow. OSEA’s portfolio is about companies, not necessarily countries.

All investments involve risk including the possible loss of principal.

Unlike mutual funds, ETFs may trade at a premium or discount to their net asset value.

Shares are bought and sold at market price not net asset value (NAV). Market price returns are based upon the closing composite market price and do not represent the returns you would receive if you traded shares at other times.

There is no guarantee that the investment objective of the Fund will be achieved. Stock markets are volatile and equity values can decline significantly in response to adverse issuer, political, regulatory, market and economic conditions. Investing in international and emerging markets poses special risks, including potentially greater price volatility due to social, political and economic factors, as well as currency exchange rate fluctuations. These risks are more severe for securities of issuers in emerging market regions. A non‑diversified Fund may invest a greater percentage of its assets in securities of a single issuer, and/or invest in a relatively small number of issuers, it is more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio.
