How to Read Taiwan Stock Margin and Short-Selling Balance
Margin BalanceMargin balance (融資餘額) measures the total leveraged long positions in a stock — rising margin indicates retail bullishness but also adds downside risk, as falling prices trigger forced sell-offs. Short balance (融券餘額) tracks shares sold short; a high short ratio combined with a rising price can create short-squeeze conditions. Blave provides daily and historical margin and short data with trend charts.
