From my article:
Meanwhile, the value of foreign investor’s holdings of Taiwanese stocks, bonds, and Taiwan dollar-denominated deposits as of the end of September rose US$4.9 billion from a month earlier to US$489 billion.
USD 4.9 billion foreign investor money in 1 month.
From your article:
Taiwanese investors overseas have returned NT$210 billion (US$7.32 billion) to the island nation since August 2019
USD 7.32 billion in more than a year from Taishang. Not so much.
