Essex Investment Management

The Global Environmental Opportunities Strategy invests in listed equities across nine environmental technology themes. It is a global, all-cap, long-only strategy with about 40 holdings focused on clean technology and energy infrastructure.

The Essex Micro Cap Growth, Small Growth and SMID Cap Growth strategies seek under-followed, under-owned and under-appreciated companies and industries in early stages of acceleration. Their shared investment philosophy is based on the belief that the small-cap asset class is inefficient.

The Essex Research Strategy is co-managed by investment professionals seeking growth equity opportunities across an all-cap universe. The team combines top-down economic and sector analysis with bottom-up stock picking to identify candidates regardless of market capitalization.

The Essex SMID Cap Growth, Small Growth and Micro Cap Growth strategies share an investment philosophy and process focused on companies in inefficient market sectors at inflection points where growth is improving.

Essex’s CO-CEO, Nancy Prial, recently was featured on CNBC Worldwide Exchange to discuss big bank earnings along with their potential deposit and loan growth as well as the impact of inflation and Fed rates. To view the entire video, please click here. Please find important disclosures here.

GEOS performance weakened in January 2024 after strong performance in November and December. The update says market sentiment favored mega-cap technology, which drove the equity market the previous year.

The company criticizes Plug Power’s announced capital raise, saying the company’s behavior harms the cleantech investment case. It says it is not invested in Plug Power.

The GEOS review says clean technology equities rallied early in the year before selling off in late July amid interest rate pressures from rising ten-year Treasury yields.
