An extremely important aspect of our activities, ensuring we continue to enhance our services and contribute to the advancement of the industry.

P1’s research and thought leadership allows us to continually improve our investment solutions for the benefit of you and your clients. Our research predominantly covers ethical and sustainable investment, stress-testing and portfolio construction.


We conduct both qualitative and quantitative investment research making sure our investment solutions are leading the way. Our research is written for a broad audience from trustees and charities to financial advisers and wealth managers. The calibre of our research permits it to be published in leading industry titles across financial services and in peer-reviewed academic journals, again cementing our work as genuinely ground breaking.

Ethical Oversight Committee

P1 has taken the unusual step of appointing an external ethical oversight committee to guide its position on ethical and sustainable investment topics and policies. We are one of only a handful of wealth managers and fund houses in the UK to adopt external monitoring of this kind.

The Ethical Oversight Committee reviews ethical and sustainability issues, and topics posed to them by the investment team to ensure that every fund P1 selects has robust ethical investment policies.  The Committee meets regularly, engages on ethical and sustainability issues, raises difficult questions and audits our process.

The Ethical Oversight Committee, combined with P1’s proprietary research, ensures that P1 selects funds that meet the highest ethical and sustainable standards.  It also helps us to avoid funds that are “greenwashed”, merely seeking an ethical label for marketing purposes.

Our Research

Ethical Investment placeholder image

Ethical Investment

In our research, we look to raise awareness about the fundamental importance of ethical investment and increase familiarity with concepts and phrases such as ‘sustainable investment’, ‘Environmental, Social and Corporate Governance’ (ESG). We also consider the various approaches used for investing ethically. At P1 investment we work hard to reflect these values in our everyday culture.

Stress-testing portfolios placeholder image

Stress-testing portfolios

Often, conventional risk measures do not fully capture all risks inherent in a portfolio, particularly under difficult market conditions.  Portfolio stress testing helps identify and quantify risks within a portfolio and can reassure an investor as to how their portfolio might respond to specific market outcomes or other concerns.

Portfolio Construction placeholder image

Portfolio Construction

Portfolio Construction theory requires critical thought in the context of the theory of investment as applied to the management of private client funds, the tailoring of a portfolio to clients’ needs and much more.  It covers topics, including: Asset Classes, Asset Allocation,  Modern Portfolio Theory, Capital Asset Pricing, Ethical Investing and Behavioral Finance.

We provide ethical and sustainable investment consultancy for those needing it.
