Philosophy

Loomis Sayles strives to be a place where true investors can thrive. Although we do not subscribe to a single investment process, the same pillars underpin all of our strategies:

Every Loomis Sayles strategy starts with a solid foundation or “alpha thesis.” This alpha thesis seeks to identify market inefficiencies and the investment process necessary to exploit them.

In this information age, being well informed is no longer a competitive advantage. High-conviction, prudent risk taking requires deep insights that can only be generated through proprietary research. Tailored research, distinct to each alpha thesis, is an inextricable part of the investment process.

Investment processes must take an exacting, consistent approach to idea generation, portfolio construction, reward-to-risk assessment and decision-making in any market environment. But discipline should never mean dogma; each team continually evaluates and refines their investment process in line with the core tenets of their strategy.

Risk management is central to alpha generation, not ancillary. Our integrated risk management capabilities are customized to each investment strategy-an approach we believe helps optimize each team’s ability to identify, analyze and utilize risk.

Though our strategies have different return patterns and time horizons, they all seek strong risk-adjusted returns. Disciplined portfolio construction requires constant assessment of reward to-risk at the security and portfolio levels. Investment teams look for asymmetric reward-to-risk opportunities and minimize exposure when information is lacking or insufficient.

Our investment teams each use a tailored approach to incorporate ESG factors and engage with issuers and companies to meet our clients’ objectives. We do not view ESG as an overlay to our investment processes. We view it as an integral component throughout.

Alpha: a measure of risk-adjusted performance. A positive alpha indicates outperformance and negative alpha indicates underperformance relative to the strategy’s level of systematic risk. ā€œAlpha engineā€ alludes to efforts to promote positive risk-adjusted excess return.

Any investment that has the possibility for profits also has the possibility of losses, including loss of principal.

There is no guarantee that the investment objective will be realized or that the strategy will generate positive or excess return.
