This guide helps readers evaluate a market announcement without assuming every subsequent price move was caused by the news. Each case connects to verified source material; a rigorous quantitative impact study also requires timestamped market data and a benchmark window.
Binance adds stock-linked derivatives
Measure trading activity after the listing, contract spreads and open interest only where reliable exchange data are available. Do not equate new listings with the issuance of company shares.
Solana tokenized equity milestone
Separate changes in holder addresses from new capital, actual trading activity and price reaction in SOL. Establish a comparison baseline before drawing conclusions.
October Federal Reserve decision
Compare Bitcoin and broad-risk-asset moves before and after the policy announcement, while accounting for other simultaneous news. The scheduled outcome has not been assumed in advance.
Methodology before publishing a numerical impact claim
Record the source release time in UTC and the announcement type; choose an observable instrument and price feed; compare pre-event and post-event windows; record market-wide benchmarks and volatility; disclose exchange, interval and data limitations. Without these inputs, a graph would risk implying false causality.
Market movements have multiple possible causes. We publish figures only when their source, instrument, observation period and calculation method can be checked.
