Taiwan's stock market jumped sharply on Tuesday, and foreign money flooded back in — good news for local shareholders, especially the 180,000 people holding Formosa Chemicals.

• The main index climbed 820 points, closing just short of the 47,000 mark, with 37 stocks hitting their daily limit.
• Foreign investors flipped from selling to buying, putting over NT$26 billion into Taiwanese shares.
• Formosa Chemicals was the standout buy, and its share price rose almost 9% on heavy trading volume.
• Banks and financial stocks also drew big foreign buying, along with old-economy names like Taiwan Cement and Formosa Plastics.
• The buying spread beyond tech, suggesting investors are rotating into cheaper, traditional companies.

Outlook: If foreign buying keeps up, the index looks set to test 47,000 in the coming sessions.
