1. Heloïse Greeff: An AI Expert with a Passion for Investment
Heloïse’s journey into the world of finance began with a deep interest in artificial intelligence (AI) and machine learning. With a PhD in Machine Learning and an MBA from the prestigious University of Oxford, Heloïse’s academic credentials are a testament to her expertise in both AI and finance. Her career began in the world of computational health informatics, where she co-invented the Oxford Smart Handpump, a pioneering technology aimed at monitoring rural health conditions.

2. Heloïse’s Investment Philosophy: Data-Driven, Long-Term Growth
Heloïse’s investment strategy is built around a combination of fundamental analysis and data-driven methodologies. At the core of her approach is the belief that AI and machine learning can be used to analyse megatrends, identify market inefficiencies, and perform valuations that traditional analysis may overlook. Her strategy prioritises long-term growth with a focus on assets that show sustainable potential over the next 5-10 years.
Key Elements of Heloïse’s Strategy:
AI and Machine Learning Algorithms: Heloïse applies bespoke machine learning algorithms to analyse financial data, identify trends, and predict future market movements. These algorithms help her make more informed, data-backed investment decisions and manage risks effectively.

Diversified Portfolio: Heloïse maintains a well-diversified portfolio that includes not only equities but also cryptocurrencies and ETFs. This diversification allows her to balance growth and risk, ensuring that her investments are positioned to withstand market fluctuations while capturing opportunities in different asset classes.
Long-Term Focus: Heloïse's approach is oriented toward long-term value creation. She recommends a minimum investment horizon of 12 months for those copying her strategy, allowing enough time for her algorithm-driven approach to realise the growth potential of the assets in her portfolio.
Risk Management: Heloïse’s strategy is considered medium-risk (rated 3/4), ensuring that the portfolio is balanced and less vulnerable to significant market shifts. She manages risk by diversifying across sectors, monitoring market conditions, and using AI to make adjustments when necessary.
Leveraging AI for Investment Success
What sets Heloïse apart is her ability to use AI to find investment opportunities that may not be obvious through traditional analysis. Her algorithms are trained to track global economic trends, market sentiment, and company fundamentals, enabling her to identify undervalued assets with high future growth potential.
