National Stock Exchange reviews on a periodic basis the contract size/value of derivative contracts based on prescribed minimum value of INR 200,000 as per SEBI circular no. SEBI/DNPD/CIR-20/2004/02/23 dated February 23, 2004. It is proposed to carry out revision of market lots for derivatives contracts.
The Underlying whose Derivative contract size /value is Higher than INR 400,000 effective December 26, 2008 will be divided by 2 and reduced to half its current size. The Underlying whose Derivative contract size /value is Lower than INR 200,000 effective December 26, 2008 will be multiplied by 2 times the existing lot.
The March 2009 expiry contracts will be revised with new market lots. All subsequent contracts (i.e., March 2009 expiry and beyond) will have revised market lots.
