Abstract

fetched live from OpenAlex

Stock prediction has been a popular research topic and researchers have done a lot of work in this field. Due to its stochastic nature, predicting the future stock market remains a very difficult problem. This paper studies the application of attention-based LSTM deep neural network in future stock market movement prediction. We also build stock aggregate dataset and individual dataset including stock history data, financial tweets sentiment and technical indicators in the US stock market. The experiment studies the time sensitivity of finance tweet sentiment and methods of collective sentiment calculation. This paper also experiments on conventional LSTM and attention-based LSTM for performance comparison. We find the finance tweets that are posted from market closure to market open in the next day has more predictive power on next day stock movement. The weighted sentiment on max follower on StockTwits also outperforms other methods. In our experiment, the result on our individual stock dataset shows a similar pattern like normal distribution.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
