XGBoost 5-Day Stock Price Predictor for Swing Trading

Author: mohan170802
Models: mohan170802/stock-price-predictor-xgboost

A production-ready XGBoost ensemble trained to predict 5-day-ahead stock price movements for swing trading. Two models per ticker:

Regression model: predicts log-return over next 5 trading days
Classification model: predicts probability that price goes UP over next 5 trading days

Supported Tickers

Ticker	Sector	Description
SPY	Broad Market	S&P 500 ETF
QQQ	Tech-heavy	Nasdaq-100 ETF
AAPL	Technology	Apple Inc.
MSFT	Technology	Microsoft Corp.
TSLA	Automotive	Tesla Inc.
NVDA	Technology	NVIDIA Corp.
AMD	Technology	Advanced Micro Devices

Model Architecture

Library: XGBoost 3.2.0
Type: Gradient Boosted Decision Trees (native Booster API)
Features: 66 engineered features per sample
Training data: 15 years of daily OHLCV (2011–2026)
Validation: Expanding-window walk-forward (5 folds, time-aware)

Feature Engineering

Category	Features
Lag features	Close & volume lags at 1,2,3,5,10,20 days
Returns	1d, 2d, 3d, 5d, 10d, 20d returns
Moving averages	SMA & EMA at 5,10,20,50 windows + price ratios
Momentum	RSI(14), MACD, MACD signal, MACD histogram
Volatility	Bollinger Bands (width, position), ATR(14), rolling std dev
Volume	OBV, volume SMA, volume ratio
Candlestick	Daily range, upper/lower shadow, body size
Calendar	Day-of-week, month, quarter, year, month-start/end flags

Performance Summary

Metric	Mean ± Std
Regression RMSE	0.0471 ± 0.0203
Regression R²	−0.0116 ± 0.0296
Directional Accuracy	0.5683 ± 0.0353
Classification Accuracy	0.4877 ± 0.0210

Key insight: Exact price prediction (R² ≈ 0) is extremely hard — the directional signal at ~57% beats random chance (50%) and is actionable for swing trades when combined with risk management.

Usage

Quick inference (single ticker)

python

import xgboost as xgb
import yfinance as yf
import numpy as np
import pandas as pd

# 1. Load model from Hub
from huggingface_hub import hf_hub_download
model_path = hf_hub_download(
    repo_id="mohan170802/stock-price-predictor-xgboost",
    filename="SPY_reg_5d.json"
)
model = xgb.Booster()
model.load_model(model_path)

# 2. Fetch latest data & engineer features
# (see stock_predictor.py in source for full feature pipeline)
# ...

# 3. Predict
X = xgb.DMatrix(latest_features, feature_names=feature_names)
predicted_log_return = model.predict(X)[0]
predicted_price = current_price * np.exp(predicted_log_return)

Batch inference with the inference script

bash

git clone https://huggingface.co/mohan170802/stock-price-predictor-xgboost
cd stock-price-predictor-xgboost
python inference.py --ticker SPY

Trading Notes

This is NOT financial advice. Models have ~57% directional accuracy — use strict stop-losses and position sizing.
Best used as one signal among many (combine with macro analysis, earnings calendar, options flow, etc.).
Retrain monthly as market regimes evolve; expanding-window CV already simulates this.
Regression model output is log-return; convert with price * exp(pred).

Training Details

Data source: Yahoo Finance via yfinance
Feature count: 66 (no leakage, all features computed from strictly past data)
Validation: Expanding-window walk-forward (5 folds)
Hyperparameters: shallow trees (max_depth=5), strong regularization (α=0.5, λ=1.0), learning_rate=0.03
Hardware: CPU (no GPU required)
Training time: ~5 minutes for all 10 tickers
