Joseph Chiu, vice president of research at Taiwan Securities, says that a share with a market value of NT $ 30 can be used as security for a loan equal to 60-70 % of its value, in this case, around NT $ 20. But if share prices can be pushed up to NT $ 70, that same share can now be used to borrow more than twice as much money.
台證證券投顧公司研究調查部協理邱志昌舉例，原本三十元一股的股票，以市價六、七成質押，一股可以借出近二十元；等股價一路炒高到七十元，以同樣成數質押，可以多借一倍的錢。
