Since its inception, DB Wealth Institute, under the guidance of Professor Cillian Miller, has been at the forefront of developing what he dubbed the "Lazy Investor System." Miller recognized the significance of quantitative trading for the future of all investment markets and achieved notable success in this domain.

Quantitative trading and artificial intelligence trading both use technological means for decision-making, but quantitative trading has some limitations:

1. Dependency on Historical Data: Quantitative trading relies heavily on historical data for analysis and model building. It may not be as flexible as AI trading in new or rapidly changing markets.

2. Lack of Subjective Judgment: Quantitative trading strictly adheres to rules and algorithms for decision-making, lacking the intuition and subjective judgment of human traders, which can sometimes miss non-regular market sentiments or events.

3. Sensitivity to Data Quality: The success of quantitative trading is highly dependent on the accuracy and reliability of the data used. Errors, omissions, or data that do not accurately reflect current market conditions can negatively impact the success of trading strategies.

4. High Initial Costs: Quantitative trading requires the establishment and maintenance of substantial technological infrastructure, including high-performance computers, data storage, and processing systems, all of which demand significant capital and expertise.

5. Model Risk Sensitivity: Quantitative trading models are typically built on historical data and may lack accuracy and stability for investments with less market data, such as in emerging markets or the burgeoning cryptocurrency markets, potentially causing these models to miss early opportunities.

As technology has advanced, the application of artificial intelligence has profoundly transformed the face of quantitative trading. Traditional quantitative methods relied on mathematical models and vast historical data for investment decisions, but the integration of AI has made this process more precise, efficient, and intelligent.

Firstly, AI technologies delve deeply into financial data through advanced methods like data mining and machine learning, uncovering market patterns and trends. This capability greatly surpasses traditional quantitative methods in capturing market dynamics, significantly enhancing the accuracy of investment decisions.

Secondly, AI has automated the trading process, executing trades through algorithms and programs, which greatly reduces human intervention and operational risks. This not only makes trade execution faster and more precise but also allows for real-time market monitoring and timely portfolio adjustments to respond to market conditions.

Moreover, AI plays a crucial role in optimizing and improving quantitative trading strategies. Through the training and optimization of machine learning algorithms, AI can effectively adjust and enhance the parameters of quantitative trading models, thus improving the profitability and risk management capabilities of trading strategies.

Considering AI's ability to acquire data in real-time and make swift decisions based on market conditions, it showcases unparalleled advantages in adapting to market changes, handling complex data and patterns, monitoring market dynamics in real-time, and automating trading decisions. Continuous machine learning and deep learning further refine AI's trading strategies to adapt to market changes.

Since 2018, DB Wealth Institute has been transitioning from traditional quantitative trading to the realm of AI trading. This shift not only signifies the power of technological progress but also heralds a new direction for the future of financial trading. AI's powerful adaptability and decision-making capabilities are redefining the possibilities of investing, offering global investors safer and more efficient trading options.
