Recommended Stock Choices

While our APIs are flexible for all stocks, we recommend focusing on stocks within the consumer goods sector, such as Procter & Gamble (PG), Johnson & Johnson (JNJ), Coca-Cola (KO), and Walmart (WMT). These companies tend to follow macroeconomic indicators and exhibit consistent performance patterns, making them ideal candidates for predictive models.

Features Used in Our Models

Our predictive models incorporate a wide array of features to capture various factors influencing stock performance:

Incorporating Market Sentiment

Market sentiment plays a crucial role in stock price movements. We incorporate sentiment scores derived from AI-powered analysis of financial news and social media as well as Put/Call Ratios. This allows our models to factor in public perception and user mood, which can significantly impact stock performance.

Our Predictive Models

We utilize XGBoost for binary classification to predict whether a stock's price will increase or decrease over the next X days. XGBoost is chosen for its ability to handle non-linear relationships, robustness to outliers, and exceptional performance on tabular data.

Why Binary Classification?
  • Simplifies investment decisions with clear directional forecasts.
  • Focuses on price movement direction rather than exact values.
Advantages of XGBoost:
  • Handles complex, non-linear data effectively.
  • Provides feature importance for interpretability.
  • Optimized for speed and performance.

For predicting exact returns X days into the future, we employ the Seasonal Autoregressive Integrated Moving Average with Exogenous Regressors (SARIMAX) model.

Why SARIMAX?
  • Incorporates exogenous variables (e.g., economic indicators, technical data) without data leakage.
  • Captures autocorrelation and seasonality in time series data.
  • Offers interpretability through model parameters and diagnostics.
Benefits:
  • Suitable for small to medium datasets.
  • Avoids overfitting by balancing model complexity.
  • Efficient and widely accepted in financial forecasting.

Model Evaluation and Validation

We understand that users need confidence in the models they rely on. To ensure the reliability and accuracy of our predictions, we employ rigorous model evaluation techniques:

Cross-Validation

We use cross-validation methods to assess model performance on unseen data, reducing the risk of overfitting.

Performance Metrics

For classification models, we evaluate:

  • Accuracy
  • Precision
  • Recall
  • F1-score
  • ROC-AUC

For regression models, we assess:

  • RMSE
  • MAE
  • MAPE
  • Confidence Scores
Feature Importance Analysis

By analyzing feature importance, we ensure that our models make decisions based on meaningful predictors, enhancing interpretability.

Preventing Data Leakage

We strictly separate training and testing datasets in time series to prevent future information from influencing model training.

User Insights

We anticipate that users may have questions about the robustness of our models and the strategies employed to ensure their reliability. Our commitment to transparency means we provide detailed insights into our modeling process, including the features used, model selection rationale, and evaluation methods. This allows users to make informed decisions based on our predictions.
