8 matches, ranked by market cap as of 2026-10-02. Refreshed at the open, midday and close.
The mirror image of the gainers page: the largest US companies that lost the most ground over the past week. Some readers treat it as a shortlist of good businesses that sold off with the tape; others use it as a risk check on positions they already hold. A sharp weekly drop can equally be the first leg of a longer slide, so the list is somewhere to begin reading rather than a verdict.
Large-cap names with the biggest down-moves this week — watchlist fodder for oversold mean-reversion or risk monitoring.
