What is SSF Block Trade? And why should you invest in SSF Block Trade?


SSF Block Trade is a method of trading Single Stock Futures (SSF), which are futures contracts based on individual stocks. It helps solve the liquidity issue on the TFEX. Brokers act as counterparties to facilitate buying or selling SSFs at the desired price and volume.

It suits investors who want to profit from both long and short positions or hedge their portfolio. SSF Block Trade requires less capital than trading actual stocks (only 5–25% margin), has lower fees, and offers the chance to receive dividends if holding a Long position until the XD date. It is a flexible tool for portfolio management in all market conditions.

Risks of Block Trade

  • Losses may be greater than direct stock investment if the market moves in the wrong direction.
  • Block Trade contracts have an expiration date.
  • The broker may not have shares available for short selling.

The minimum contract size for Block Trade transactions varies by underlying stock, as specified by TFEX—set at 20, 100, 500, or 1,000 contracts.
Investors must trade at least the minimum contract size, but do not need to trade in multiples of that number. For example, if the minimum for PTT is 100 contracts, investors can place orders of 100, 101, or 102 contracts, and so on.

When a Corporate Action occurs—such as a Right Offering, Stock Split, Reverse Stock Split, Stock Dividend, or Special Cash Dividend—TFEX will adjust the contract specifications of the Single Stock Futures to ensure investors are either not affected or affected as little as possible. Adjusted contracts will have a suffix added to the original contract name:
  • "X" for the first adjustment
  • "Y" for the second adjustment
  • "Z" for the third adjustment

SSF Block Trade can be placed only through an investment consultant.

No. Investors must close their positions by 4:00 PM on the contract's expiration date.
