StockQuantLabHow to evaluate stock news
News affects a stock when it changes expected cash flow, risk, or the valuation multiple investors are willing to pay. A positive headline can still lead to a negative price reaction if the market expected more.
Source discipline
StockQuantLab provides links to original publishers where available. Automated summaries and impact labels are screening aids. Readers should open the source article and verify material claims through company filings or official disclosures.
