- Boston Partners Long/Short Research Fund (BPIRX) is an institutional class mutual fund managed by Boston Partners Global Investors, Inc., which employs a long/short equity strategy focused on undervalued long positions and overvalued short positions across large-, mid-, small-, and micro-cap companies; the fund also invests in equity securities and convertible instruments, with proceeds from short sales allocated to short-term cash instruments yielding just below the federal funds rate. Launched on September 29, 2010, the fund targets institutional investors with a minimum investment of $100,000 and carries an expense ratio of 1.40%, operating primarily in U.S. equity markets through a blend style approach. Boston Partners, the fund's adviser founded in 1995 and headquartered at One Beacon Street, 30th Floor, in Boston, Massachusetts, manages a range of value equity strategies including U.S., global, international, emerging markets, long/short, and small/micro-cap products for institutional and intermediary clients.
The fund's core offerings emphasize bottom-up fundamental research to identify stocks with attractive valuations, strong business fundamentals, and positive momentum, maintaining a market-neutral profile through balanced long and short exposures. It provides institutional class shares (BPIRX) alongside investor class (BPRRX), with distributions including dividends and capital gains, such as a 10.03% trailing twelve-month yield in recent periods. Geographically, the strategy centers on U.S.-listed equities but may include global exposure via holdings, serving endowments, foundations, corporations, Taft-Hartley plans, and financial intermediaries.
Recent developments at Boston Partners include strategic hiring expansions in 2025 to support continued client growth and acquisitions, such as additions to the client relations, equity research, trading, and investor relations teams; key hires feature specialists in energy, healthcare, emerging markets, and private wealth services. In January 2025, the firm bolstered its account consultant team amid unprecedented growth, while July 2025 announcements highlighted new client wins and operational enhancements. Portfolio adjustments, like increasing stakes in holdings such as Nomad Foods in August 2025, reflect ongoing active management, with no major acquisitions, funding rounds, or structural changes reported for the fund itself in the past 1-2 years.
