What You Can Use Taiwan Foreign Ownership For

Track foreign flows into a Taiwan name at daily resolution. See how close a security sits to its foreign-ownership ceiling. Cross a foreign-ownership build against monthly revenue or a price move.

The Ceiling Is Not the Holding

foreign_limit_pct is the regulatory ceiling for that security, not the amount held. It is usually 100 and lower for the restricted industries.foreign_held_pct is the amount actually held. The two are different facts and are routinely confused.

Key Taiwan Foreign Ownership Fields

Shares issued and shares held by foreign investors give the raw counts. foreign_held_pct is the percentage held and foreign_limit_pct is the ceiling. Both percentages are on a 0-to-100 scale, not fractions.
