Research Interests

Ethical and Sustainable 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 – 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 –  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.

Risk & Risk Management – Our research into risk looks to highlight potential vulnerabilities in traditional assumptions towards risk and how these can break down in cases of extreme market events.

Targeted Audiences

Our research is primarily designed to aid and optimize our portfolio management to provide the best possible service to our clients. In addition to this, it should also help professionals that work in the wealth management and financial services sector improve the quality of their service proposition. In addition to grouping articles by topic they have also been organised in terms of the different professions operating in financial services.

These include:

Independent Financial Advisers – Research and discussion points designed to support IFAs deliver the best possible solution to their clients.

Wealth Managers – For fellow wealth management professionals.

Trustees – For professional trustees, including accountants, actuaries and lawyers who are involved in the oversight of, or have fiduciary responsibilities for trust or pension assets.

Technical Practitioners – Advanced research and analysis, potentially involving more complex mathematics.
