5. How this was built

Warrants and leveraged ETFs were removed before grouping — they crowd out the underlying names they track. 50 tickers survived that filter. Every number here comes from market data. The theme names and the one-line explanations are written from the day's headlines — where a group moved with no headline behind it, we say so rather than inventing a reason. This is an observation of what moved, not advice and not a recommendation. This tells you where attention went today; it does not tell you what happens next.
