Pear Tree Essex Environmental Opportunities Fund

The PEAR TREE ESSEX ENVIRONMENTAL OPPORTUNITIES FUND operates at the nexus of environment and finance, investing in companies that enable greater natural resource and energy efficiency.

Investment Process

The Fund invests in companies the management team believes solve environmental and related social challenges, seeking to provide attractive financial and social impact returns. The Fund invests in public equities with full alignment to the U.N. Sustainable Development Goals. Investments are made across nine environmental themes, providing clean technology diversification in companies with revenue and earnings growth greater than the broad equity market, in companies exhibiting effective capital allocation and strong profitability.

Buy and Sell Discipline

The Fund is concentrated, typically owning 35-45 equity holdings, in growth companies which provide solutions to the world's environmental challenges. Stock selection is based on rigorous fundamental company analysis and a valuation process that is informed by the portfolio management team’s thematic industry assessment. The Fund is generally lower turnover, with half from existing positions. Position sizes average 2-3%, and are diversified across themes, geographies and industries. Risk management and assessment is integral to portfolio construction, with position sizes determined by industry maturity, liquidity, individual security volatility and the management of price and profit expectations.

Portfolio Management

The Fund is managed by William Page and Robert Uek of Essex Investment Management, LLC. Essex is an independent, employee-owned firm with over a 40-year history of growth equity investing. Page and Uek have almost 60 years of combined institutional investment experience. The portfolio management team has been managing clean technology portfolios for over 16 years, with the first listed impact strategy in North America.

For the Quarter ended March 31, 2024

The Pear Tree Essex Environmental Opportunities Fund’s Ordinary Shares (the “Fund”) underperformed its benchmark, MSCI World Index (the “Index”).  The Fund achieved a return of (1.47%) at net asset value compared to 9.01% for the Index.¹

Market Conditions and Investment Strategies

Fund performance was hindered early in the quarter as market sentiment continued to favor large market capitalization stocks, primarily the Information Technology sector. Investors remained risk averse in our opinion and this will continue until investors observe the Federal Reserve initiating lower interest rates. Fund performance improved during the remainder of the quarter, relative to the Index, driven by a generally favorable fourth quarter earnings season for the Fund’s holdings.

Portfolio Changes

Fund positions were sold where declining fundamentals were anticipated, such as Aptiv, designer of electric vehicle systems, and Bloom Energy, whose profitability we believe is at risk. Trimble was purchased, which delivers technology used in agriculture, construction and surveying, with the precision agriculture business the fastest growing segment, enhancing farmer returns on investment and reducing inputs as well as harmful nutrient runoff using precise fertilizer applications. Watts Water Technologies was sold based on a high valuation, and Xylem was purchased, the diversified water solutions company, based on what we believe
will be higher sales to commercial and municipal channels. Later in the quarter we initiated a small position of the electric vehicle manufacturer Rivian. While the electric vehicle industry is experiencing some growth challenges currently, we believe the trend is intact longer term and Rivian has the potential to be differentiated with strong product offerings. MYR Group was purchased, given our high conviction for increased spending to shore up and modernize the electrical grid. MYR Group is well positioned, we believe,
as a market leader in electrical construction services.


One of the Fund’s themes in which we have high conviction is companies enabling a more efficient electrical grid in the Fund’s power technology theme. The companies enabling electricity delivery and grid modernization have done well over the past several years, but there is a step change happening now. The demand drivers such as onshoring industry, and the rise of solar power are rapidly increasing the need for an enhanced grid, and this trend we expect will accelerate. The Fund has extensive exposure to our
power technology theme, and while these companies drove performance for the first quarter of 2024, we believe we are still in early innings. There are two primary drivers in place that are leading to the step change in spending of our electrical grid, and we believe they are multi-faceted. While data center electricity needs have increased marginal demand the past few years, artificial intelligence will compound it by over 60% in the next several years. Boston Consulting Group estimates that data centers will soon use as much power as 40 million homes – more than residential demand in California. The second driver is onshoring: the new mantra, echoing from shore to shore in bipartisan fashion is build it here in America. According to Fund power technology holding Primoris Services, almost 70% of US manufacturers surveyed have begun reshoring efforts in the past year. This trend has been catalyzed by the Inflation Reduction (IRA) and Chips Acts, which incentivize US-based manufacturing with state and local tax incentives. While AI is an exciting technology that will transform our economy, it is not feasible without electricity, and is just one of the many catalysts in the power technology theme.
