Day 2 of 30: AMZN ML Prediction Challenge

StrangeArugala · 2026-05-27T04:39:29+00:00

=== SUMMARY === - Post is a daily 30-day challenge where the author uses a LightGBM model to predict the next-day close direction for AMZN (higher or lower). - The model correctly predicted Day 1 (lower close) and now predicts Day 2 will also be lower than the prior close of $265.29. - The author is publicly tracking results with a transparency sheet; the post is a live experiment, not financial advice. - Quality assessment: This is a low-confidence, single-asset algorithmic trading diary. While the setup uses technical features and walk-forward testing, the sample size is tiny (1 day correct) and the stated confidence is only 46%, making it closer to speculative noise than well-researched DD. === SENTIMENT === BEARISH === TRADE IDEAS === AMZN - SHORT | confidence: 0.46 | sentiment: -0.3 Speaker: u/StrangeArugala Thesis: 1. THE FACT: The LightGBM model predicts AMZN’s next trading day close will be lower than the previous close of $265.29. 2. THE BRIDGE: If the model’s signal is correct, a short position entered near the prior close could capture the predicted decline. 3. THE VERDICT: Trade is based solely on a low-confidence (46%) daily ML signal with technical indicators (SMA/EMA) and walk-forward validation, not on fundamental or macro analysis. 4. RISKS: Extremely low confidence, overfitting risk with daily data, no position sizing or stop-loss details provided, and a sample of only one correct prediction. Timeframe: short-term (intraday or next close) Key Points: - Model uses SMA 10/100/200, EMA 10/100/200 + MinMax normalization. - Confidence only 46% – nearly coin-flip. - Only one prior correct prediction (Day 1). - No explicit risk management or position size. - Author explicitly states “not financial advice.”
