Stock Borrowing & Lending Process

Borrow Stock:

  • Open a short sell account with CHIEF;
  • Enquire CHIEF if the desired stock is available for short selling;
Short Selling:
  • Once stock borrowing is confirmed by CHIEF, you can contact designated staff to make short sell instruction;
  • Initial margin is required to deposit before 5:00pm on T day;
    (For example, 1000 shares of Tencent (#00700) are successfully sold (Selling price $100), initial deposit: 125%, where 25% of the transaction amount is $25,000 and 100% is principal of short sell)
  • The calculation of SBL Loan interest start at settlement day (T+2)
Example 1:

Maintenance Margin is 115% of market value

If Tencent (#00700) price rises to $110

Margin ratio = 114% [125,000 / (110*1000), lower than 115%]

Since the margin ratio is lower than 115%, Margin deposit is needed.

Deposit amount= $11,250 [1.25 * (109 * 1000) - 125,000]

Example 2:

If Tencent (#00700) price falls to $90

Margin Ratio = 139% [125,000 / (90 * 1000), larger than 115%]

No margin deposit is needed.

Stock Return:
  • You can buy back through Internet or our staff. After that, you must inform CHIEF, otherwise the return process will not be completed;
  • The loan fee will be deducted from the short sell account at settlement day (T+2).


  • Short sell order can only be made when stock borrowing is confirmed by CHIEF;
  • The short sell order must be conducted in continuous trading session, and the selling price must not be lower than the ask price;
  • If the price keeps rising, the client will bear unlimited floating loss;
  • If the dividend payment occurred, the company will deduct the dividend from your account at the Ex-Dividend date.
