Not financial advice.
Today's Movers
Semiconductor stocks with the largest single-day price change. Includes NYSE, NASDAQ, TWSE, KOSPI, and other major exchanges.
30-Day Movers
Price change over the trailing 30 calendar days. Useful for tracking momentum after earnings, technology milestones, or geopolitical events affecting chip supply chains.
Market-Moving Headlines
Recent semiconductor news the coverage pipeline flagged as market-moving: earnings surprises, capacity announcements, export controls and supply agreements that moved chip stocks. Sentiment is scored automatically and is a summary of the headline, not investment guidance.
Market Cap Ranking
The largest fab-owning semiconductor companies by market capitalisation, from trillion-dollar foundries and memory giants to specialised IDMs and emerging players. Converted to US dollars at rates refreshed alongside the prices.
3-Month Return
Share price change over the trailing three months, from the daily close series. The sparkline beside each row shows the full trailing twelve months, so a three-month gain inside a longer slide is visible rather than hidden.
Fabs Owned
Number of fabrication, assembly and test sites FabulousMap tracks for each listed company, at every lifecycle stage. A high count reflects a broad manufacturing footprint, not necessarily a large one: a single leading-edge megafab can outweigh a dozen mature-node lines.
