18.5 Position Limits
18.5.1 Members Prohibited from Opening Transactions that would Violate Individual Position Limits
Except with the prior written approval of SGX-ST in each instance, no Trading Member shall, for any account in which it has an interest or for the account of any customer, effect an opening transaction in an Option of any Class dealt on SGX-ST if that Trading Member has reason to believe that as a result of such transaction the Trading Member or its customer would, acting alone or in concert with others directly or indirectly, hold or control or be obligated in respect of an aggregate position (whether short or long) in excess of the individual position limits set out as follows:—(1) 2,000 Options on the same side of the market where the issued capital of the issuer of the underlying securities is less than 400 million shares. The aggregate position limit for both sides of the market shall accordingly be 4,000 Options.(2) 3,000 Options on the same side of the market where the issued capital of the issuer of the underlying securities is between 400 million and 600 million shares (both numbers inclusive). The aggregate position limit for both sides of the market shall accordingly be 6,000 Options.(3) 4,000 Options on the same side of the market where the issued capital of the issuer of the underlying securities is more than 600 million shares. The aggregate position limit for both sides of the market shall accordingly be 8,000 Options.
18.5.2 Market Position Limits
Notwithstanding Rule 18.5.1 the total number of outstanding Options on both sides of the market of any underlying security shall not exceed 15% of the issued capital of the issuer of the underlying security. This limit shall be known as the market position limit.
18.5.3 Position Limits Subject to Change
SGX-ST may from time to time vary the individual position and market position limits in Rules 18.5.1 and 18.5.2 respectively by a circular issued to all Trading Members, such new position limits to take effect on such date specified therein. Such new position limits shall not, unless otherwise stated, affect existing Options positions.
18.5.4 Definition of "Control"(1) For purposes of aggregation of Option positions under Rule 18.5.1, control may be presumed by SGX-ST:—(a) when a person has the power or ability to make investment decisions for an Options trading account; or(b) when a person has the power or ability to influence directly or indirectly the investment decisions of any person who makes investment decisions for an Options trading account. A person who has such power or ability shall be presumed to control such account unless and until the presumption is rebutted by evidence and a determination to the contrary has been made by SGX-ST.(2) Control will be presumed in the following circumstances:—(a) among all parties to a joint account who have authority to act on behalf of the Options trading account;(b) when a person holds an ownership interest of 10% or more in a Corporation (ownership interest of less than 10% will not preclude aggregation);(c) when Option trading accounts have common directors or management; or(d) where a person or entity has the authority to execute transactions in an Options trading account.
18.5.5 Reports Relating to Position Limits(1) Each Trading Member shall, when required to do so or if it comes to their knowledge, file with SGX-ST a report, in such form as may be prescribed, giving the name and address of any customer who, on the previous Market Day, holds aggregate long or short positions on the same side of the market in excess of the individual position limits fixed by SGX-ST from time to time. The report shall indicate the number of Options comprising each such position.(2) In addition to the reports required under Rule 18.5.5(1), each Trading Member shall report promptly to SGX-ST any instance in which it has reason to believe that a customer, acting alone or in concert with others has exceeded or is attempting to exceed the individual or market position limits established by SGX-ST from time to time.
18.5.6 Closing Off Positions
Whenever SGX-ST shall determine that a person or group of persons acting in concert holds or controls, or is obligated in respect of, an aggregate position (whether long or short) in all Options of 1 or more Classes or Series dealt in on SGX-ST in excess of the applicable position limits, it may order all Trading Members carrying a position in Options of such Classes or Series for such person or persons to enter into closing transactions in respect of such outstanding positions as expeditiously as possible consistent with the maintenance of a fair and orderly market. Whenever such an order is given, no Trading Member shall accept any order to write, purchase or exercise any Option for the account of the person or persons named in the order, unless in each instance express approval therefor is given by SGX-ST, or until such order is rescinded.
18.5.7 Trading Member's Duty to Inform Customers of Position Limits
It shall be the responsibility of each Trading Member and Trading Representative accepting orders for opening transactions (purchase or written) in Options to inform customers of the applicable position limits and not to accept orders from any customer if the Trading Member or Trading Representative has reason to believe that the customer, acting alone or in concert with others, has exceeded or is attempting to exceed such position limits.
18.5.8 Limit on Uncovered Short Positions
Whenever SGX-ST or the OCC shall determine in light of current conditions in the Options Market or in the Equity Market that there are outstanding an excessive number of percent of uncovered short positions in Options of a given Class dealt in on SGX-ST, SGX-ST or the OCC may prohibit any further opening written transactions in Options of that Class unless the short position is created by a Scrip-Covered Call Option and it may prohibit the uncovering of existing Scrip-Covered Call Options in 1 or more Series of that Class as it deems appropriate in the interests of maintaining a fair and orderly market in such Options or in the underlying securities, or otherwise deems advisable in the public interest or for the protection of investors.
18.5.9 Other Restrictions on Option Transactions and Exercises
SGX-ST or the OCC shall be empowered to impose, from time to time in its discretion, such restrictions on Option transactions or the exercise of Options in 1 or more Series of Options of any Class dealt in on SGX-ST as SGX-ST or the OCC deems advisable in the interests of maintaining a fair and orderly market in Options, or in the underlying securities or otherwise deems advisable in the public interest or for the protection of investors. During the effectiveness of such restrictions, no Trading Member shall, for any account in which it has an interest or for the account of any customer effect any Option transaction or accept Exercise Notices to exercise any Option in contravention of such restrictions.
