Top stock losers today
These are the stocks with the biggest falls today across the four markets we cover: US large caps, Borsa Istanbul (BIST), Tokyo and China/Hong Kong, ranked by their change against the previous close. Each exchange keeps its own hours, so the label under each name tells you where the stock trades. A sharp drop often follows earnings, guidance or company news, but it can also reflect a broad sell-off — check the stock's chart and analysis before drawing conclusions.

Frequently asked questions
How is this list calculated?
We take the stocks on our US, BIST, Japan and China/Hong Kong lists, leave out index quotes, and sort the rest by their change against the previous close. Up to 25 stocks that fell are shown.
Is a big drop a buying opportunity?
Not necessarily. A falling price can keep falling, and the reason for the drop matters more than its size. Look at the company's chart, news and fundamentals and consider your risk tolerance — nothing here is investment advice.
Not investment advice.
