GitHub Actions runs MegaCap_update_prices.py daily. It fetches live prices, 1D/1W/1M/YTD returns, P/E, short interest, analyst scores and up to 5 recent headlines with sentiment scores for all 50 mega-cap stocks via Yahoo Finance.
Before ranking, the model is directed to search online for the latest news on the top 10 highest-momentum stocks — surfacing earnings beats, product launches, AI infrastructure spending, M&A activity, regulatory developments, and macro rate moves.
MegaCap_generate_signals_local.py sends the full dataset to deepseek/deepseek-v4-flash via OpenRouter with the web search plugin enabled. The model scores each stock across momentum, fundamentals, analyst consensus and live news sentiment, then returns a ranked top 10 in JSON.
The full pipeline runs automatically every Monday, Wednesday and Friday. You can also trigger it manually from the GitHub Actions tab, or run python MegaCap_generate_signals_local.py locally to generate fresh signals on demand.
