Financial Investment Decision Based on Topological Data Analysis
This paper explores a financial investment decision making methods based on Topological Data Analysis (TDA), aiming to uncover the intrinsic structures and patterns within financial market data through TDA, thereby enhancing the accuracy and efficiency of investment decisions. With the advent of the big data era, the complexity and volume of financial market data have increased dramatically. Traditional investment analysis methods face limitations when dealing with high-dimensional, nonlinear, and complex data. As an emerging data analysis approach, TDA can identify features such as clusters, voids, and connectivity within data, revealing the topological structure of data at different scales. This provides a new perspective for financial investment decision-making.
Executive Impact Summary
This paper presents a novel approach to financial investment decision-making by leveraging Topological Data Analysis (TDA). TDA uncovers hidden structures and patterns in complex financial market data, overcoming limitations of traditional methods. The proposed TDA-based model, incorporating Golden Cross and Death Cross strategies, demonstrated promising performance in backtesting, achieving stable asset appreciation and providing robust support for investment decisions, particularly during high volatility periods.

Uncovering Market Dynamics with Takens' Embedding
Takens' embedding is a fundamental technique for reconstructing the state space of a dynamical system from a single-variable time series. This method transforms financial time series data into a multidimensional point cloud, where specific geometric patterns emerge if the original series exhibits periodic or chaotic characteristics. This transformation is crucial for TDA as it provides a suitable geometric representation of the data, allowing for the subsequent analysis of its topological features. It enables a shift from one-dimensional time series to higher-dimensional spaces where intrinsic structures become discernible.
Stable
Topological Feature Representation
The persistent landscape offers several advantages over persistence diagrams, including forming a Hilbert space and being inherently stable. By representing topological features as functions, it eliminates the need for parameter tuning and reduces computational time, making it a robust and efficient tool for analyzing the lifecycle of topological features in financial data.
TDA Norm for Enhanced Volatility Measurement
| Feature | Traditional Std. Deviation | TDA Norm |
|---|---|---|
| Volatility Capture | Brief fluctuations | Prolonged high volatility |
| Outlier Robustness | Sensitive to outliers | Greater robustness |
| Market Signals | Less precise | More accurate during collapse cycles |
| Mathematical Basis | Descriptive statistics | Algebraic structures |
| Interpretation | Magnitude of price changes | Topological changes in data structure |
The TDA norm provides a more robust and accurate measure of market volatility compared to traditional standard deviation. It effectively captures prolonged periods of high volatility and is less sensitive to outliers, particularly during financial collapse cycles, offering a deeper insight into market signals based on the algebraic structures of return series.

Golden Cross and Death Cross Model with TDA Norms: Enhanced Trading Signals for WMT
This case study demonstrates the application of the Golden Cross and Death Cross model, integrated with TDA norms, to the stock WMT. Traditional models often show funds in a loss state during volatile periods. However, by leveraging TDA norms, the model achieves more stable asset appreciation and provides robust buy-sell signals, indicating improved performance compared to conventional approaches. The filtering strategy ensures that assets susceptible to significant losses are avoided, leading to more resilient portfolio construction. This integration offers a new perspective on capturing medium-term market trends with enhanced accuracy.
