The future of AI in personal finance
Joy Wallet: How do you envision AI transforming personal finance and investment planning in the near future?
Martin: Many financial service providers (e.g., banks, stock trading platforms, private banking institutions) now offer programmable interfaces through APIs, allowing individuals to integrate AI features into their financial decision-making processes, such as stock trading, savings, and retirement planning. These autonomous interventions are expected to become increasingly available, benefiting both individuals and the industry. This accessibility simplifies access to financial services, especially for those less familiar with financial information.
Navigating volatility
Joy Wallet: Could you explain how reinforcement learning and AI can enhance investment strategies, particularly during times of market volatility?
Martin: In my research paper, Development of an AI Framework Using Neural Process Continuous Reinforcement Learning to Optimize Highly Volatile Financial Portfolios, I do not claim that reinforcement learning models will replace conventional portfolio management processes.
Instead, we propose that allowing an RL agent to select the appropriate portfolio optimization methods by learning from the capital market environment offers advantages over solely using machine learning.
While machine learning is potentially more effective than traditional statistical methods for understanding volatility due to its capacity for handling high-dimensional data, portfolio management decisions should incorporate conservative, mathematically rigorous approaches that account for parametric, analytical, or continuous factors to ensure both stability and profitability. In this respect, conventional statistical methods often outperform machine learning. The integration of hybrid methods presents a novel investment strategy for the financial industry.

AI for beginners
Joy Wallet: For someone new to personal finance, what advantages could AI bring to their investment decisions?
Martin: For someone new to personal finance, AI offers significant advantages in investment decisions by providing accessible and user-friendly platforms that simplify complex financial concepts and are available 24/7. AI delivers personalized investment advice by analyzing an individual's financial situation, goals, and risk tolerance to tailor strategies while adapting to changing circumstances through continuous learning. It performs comprehensive data analysis, processing vast amounts of market information to identify trends and forecast outcomes, enabling more informed decision-making. This automation leads to cost-effectiveness with lower fees compared to traditional advisors.
Furthermore, AI offers scalability and flexibility, adjusting investment strategies as market conditions or personal finances change, making sophisticated investment tools accessible and manageable for beginners. This means that investors could have a better chance to generate more profits.
Tailoring to risk
Joy Wallet: How can AI-based financial tools account for individual risk tolerance when making investment recommendations?
Martin: AI-based financial tools can effectively account for individual risk tolerance by leveraging their ability to perform fast and accurate predictions, which are essential for minimizing investment risks. These tools begin by gathering comprehensive data on an individual’s financial situation, investment goals, and risk preferences through questionnaires and behavioral analysis. AI can rapidly analyze this data alongside vast amounts of real-time and historical market information to identify patterns and forecast potential market movements.
By accurately predicting market trends and volatility, AI tools can tailor investment recommendations that align with the user’s risk tolerance, ensuring that portfolio allocations are optimized to balance potential returns with acceptable risk levels.
AI continuously monitors market conditions and the individual’s portfolio performance, allowing for dynamic adjustments that respond swiftly to any changes, thereby mitigating risks proactively. This real-time adaptability, combined with precise predictive capabilities, enables AI-based financial tools to provide personalized, resilient investment strategies that cater to each user's unique risk appetite, ultimately fostering more secure and confident investment decisions.
Overcoming skepticism
Joy Wallet: What advice would you give individuals who may be hesitant to use AI-driven tools in their financial planning?
Martin: Even if you are hesitant to use AI-driven financial tools, chances are you’re already benefiting from them without realizing it. Media outlets, banks, credit card companies, and other financial institutions continuously collect and analyze your data, indirectly exposing you to AI-driven insights and services. While technological apprehension is understandable, rejecting AI tools entirely is impractical today, similar to arguing for eliminating television simply because you believe the subscription fee is a waste.
Instead of avoiding AI, consider embracing it by starting with small, low-risk investments using reputable AI platforms, educating yourself about how these tools work, and choosing services that prioritize data security and transparency. This approach allows you to leverage the advantages of AI in financial planning while maintaining control and confidence in your investment decisions.

High-risk, high-reward portfolios
Joy Wallet: In your research, what are the most effective ways AI can help manage high-risk, high-reward portfolios?
Martin: Across my research, I have argued that AI enhances high-risk, high-reward portfolio management by providing dynamic market prediction and adaptability, enabling the model to react swiftly to market shifts. AI leverages high-dimensional data analysis to accurately assess risk and optimizes portfolios, balancing returns with risk tolerance and tailoring strategies like hedging and diversification to market conditions. Automated decision-making and rebalancing allow AI to manage portfolios efficiently in volatile environments, reducing the need for manual intervention.
Scenario analysis further strengthens this approach by preparing the model for extreme market conditions, while integration of diverse data sources, such as economic indicators and market sentiment, allows AI to construct a comprehensive risk assessment. These capabilities together support a proactive, data-driven portfolio management approach that aligns with the objectives of high-risk, high-reward investing in investment decision-making.
Challenges in unpredictable markets
Joy Wallet: Could you discuss any specific challenges AI faces in adapting to unpredictable financial markets?
Martin: One of the primary challenges AI faces in adapting to unpredictable financial markets is the highly volatile nature of financial time series data, which often updates at different rates across various assets and indicators. This inconsistency in update speeds and volatility complicates accurate predictions for machine learning models.
Many researchers, including myself, have been working to address these issues by developing models that can handle such irregularities and better align with the unique dynamics of financial markets. Unlike more predictable fields such as inventory or demand forecasting, financial time series require approaches tailored to extreme uncertainty. This means researchers must specifically craft AI models to adapt to diverse market conditions, allowing them to respond flexibly to the distinct unpredictable patterns inherent in financial data.
AI vs. traditional advisors
Joy Wallet: Do you think AI and machine learning will eventually replace traditional investment advisors, or will it remain a complementary tool?
Martin: AI and machine learning have already taken on a dominant role in financial markets, effectively functioning as key drivers behind much of today’s trading activity. For example, around 60–80% of total trades in the US stock market are now algorithm-driven, while in the global foreign exchange market, roughly 20% of trades are conducted through algorithmic systems. This trend reflects the depth of AI's integration into finance, where machines are frequently relied upon to execute large-scale, high-frequency trades more efficiently than humans.
However, in areas like personal investment advising and customized financial planning, AI remains more of a complementary tool rather than a replacement for traditional advisors. While AI excels in processing vast datasets and providing predictive analysis, human advisors bring essential elements of judgment and relationship management that machines cannot fully replicate. This synergy allows for more balanced financial decision-making, leveraging the strengths of both AI and human expertise.

AI-optimized strategies
Joy Wallet: Are there specific investment strategies you believe could benefit most from AI technology?
Martin: Yes, high-frequency trading, risk management, and portfolio optimization are investment strategies that benefit significantly from AI. AI excels at analyzing large data sets in real time, allowing it to identify patterns, predict trends, and manage risks more effectively than traditional methods, making it ideal for these fast-paced and data-intensive areas.
Achieving long-term goals
Joy Wallet: How might AI assist investors in achieving long-term financial goals, such as retirement planning?
Martin: AI can play a crucial role in helping investors achieve long-term financial goals, such as retirement planning, by providing a personalized, adaptive, and data-driven approach.
For instance, AI assesses an investor’s unique financial profile, including income, spending habits, and savings potential, alongside factors like risk tolerance and anticipated retirement age. Using this information, AI-driven platforms can create tailored investment strategies aligned with the investor’s long-term objectives, such as wealth accumulation or steady income generation.
In addition, AI continuously monitors market conditions and adjusts portfolios as needed, automatically rebalancing investments to optimize performance based on real-time market data and economic forecasts.
Considerations before adoption
Joy Wallet: What should individuals consider before integrating AI-driven tools into their financial plans?
Martin: Before integrating AI-driven tools into their financial plans, individuals should prioritize building a foundational understanding of financial concepts. Many people find financial information and terminology intimidating, as it often appears complex and math-heavy. However, financial principles are actually quite intuitive and accessible once you invest the time to learn them. By patiently developing a basic knowledge of finance, individuals can gain confidence in navigating AI tools and making sense of their investment strategies.
Financial knowledge is invaluable and remarkably straightforward compared to other fields; there are few areas that are as universally beneficial and easy to grasp over time. A strong grasp of these fundamentals enables individuals to use AI-driven tools more effectively, making well-informed decisions that align with their personal financial goals.
Day-to-day decisions
Joy Wallet: What potential do you see for AI in helping people make everyday financial decisions, like budgeting and saving?
Martin: AI has the potential to be your financial sidekick, helping you make everyday decisions like budgeting and saving with the finesse of a digital “money whisperer.” Imagine having an assistant that gently reminds you that maybe, just maybe, five coffee subscriptions and a streaming service for each genre are a bit much.
AI-driven tools can track your spending habits and, without judgment (okay, maybe a little), nudge you toward sticking to your budget or finding clever ways to save without cramping your style.
Need to save for that emergency fund? AI’s got your back, suggesting small but steady savings moves that won’t make your wallet cry. It can even flag those sneaky fees and high-interest payments, saving you money in ways you never thought possible. In short, AI brings a bit of order to financial chaos, making saving and budgeting feel less like a chore and more like having a financially savvy friend who’s always looking out for you.

Finding joy
Joy Wallet: What brings you the most joy in life?
Martin: As an AI, finance, and security researcher, you might think my greatest joy comes from debugging code at 3 am or spotting patterns in chaotic financial data — and you’d be right, in part! But when I'm not knee-deep in algorithms and market models, my idea of fun is almost normal. I love the thrill of teaching AI to solve complex problems like a proud parent watching their “robot child” take its first steps into uncharted datasets, especially when I see neural networks successfully grasp complex non-linear patterns.
There’s also something hilarious about using my cybersecurity skills to secure my passwords — encrypted 50 times over — which leaves my colleagues wondering if I'm harboring state secrets (who knows, maybe I am). Of course, nothing tops the excitement of breaking down complex research findings for people who, if we’re honest, are mostly here for the pizza. Life’s real joy? Watching people realize AI isn’t scary — unless, of course, it’s finally helping me automate my protein shake orders.
