Trading Calendar

     SET50 Index Options is a contract that gives the buyer the right, but not the obligation, to buy or sell SET50 Index at a specific price on or before a certain date. An option, just like a stock or bond, is a security. It is also a binding contract with strictly defined terms and properties. The advantage of options is that you aren't limited to making a profit only when the market goes up. Because of the versatility of options, you can also make money when the market goes down or even sideways. SET50 Index Options is the second product on TFEX and was launched on October 29th, 2007.
