Frequently Asked Questions

What does Ecofi Investissements Sa invest in?
Ecofi’s investment strategy is fundamentally driven and explicitly anchored in ESG and SRI principles. At the group level, the firm manages diversified strategies across asset classes, but the sleeve visible in Form 13F is the long-only U.S. equity component within its global and regional equity mandates and multi-asset funds. For equities, Ecofi typically applies a two-step process: 1. **ESG and SRI filtering:** The investment universe is screened using exclusion criteria (e.g., controversial weapons, severe environmental or social controversies), sectoral and norms-based exclusions, and positive selection based on ESG ratings or proprietary assessments. This yields a universe of issuers aligned with the firm’s sustainability standards or SRI labels. 2. **Fundamental bottom-up selection:** Within the ESG-screened universe, portfolio managers and analysts conduct detailed company analysis. They focus on business quality, competitive positioning, balance-sheet strength, cash-flow durability, and governance, integrating financially material environmental and social risks into valuation work. Emphasis is placed on: - Understandable, cash-generative business models. - Sensible capital allocation and shareholder alignment. - Visibility on growth drivers and margins. In practice, this leads to portfolios that are diversified across sectors but structurally tilted toward quality issuers and ESG leaders. Sector weights in the U.S.-listed sleeve emerge from stock-by-stock decisions rather than top-down sector targets. Ecofi’s holding periods tend to be multi-year, reflecting its long-term, responsible-investor stance. Turnover in the U.S. equity sleeve, as inferred from 13F filings, is generally low to moderate: core positions often persist across multiple quarters, while changes mainly arise from valuation discipline, fundamental reassessments, or index and liquidity considerations. Beyond standalone equity mandates, Ecofi embeds equities within multi-asset and balanced strategies. In those cases, the U.S.-listed holdings that appear in 13F filings represent the equity building blocks of broader portfolios that also include euro and global bonds, money market instruments, and potentially alternative exposures, none of which are visible in the 13F dataset. Within a Portfolio Simulator or Backtesting Service, Ecofi’s disclosed holdings can be mapped to market prices and normalized to a user-defined notional to construct an approximate **Historical Track Record** for the U.S.-listed sleeve. This enables allocators to analyze how Ecofi’s combination of fundamental selection and ESG integration would have interacted with different U.S. equity regimes, while recognizing that non-U.S. and fixed income exposures, along with intra-quarter trading, are outside the 13F lens.
