These revisions are part of a periodic exercise aimed at keeping the contract value in the ₹5-10 lakh range
On the NSE, the lot size of 43 stocks will be revised upward, while that of 5 stocks will be reduced. In the case of 2 stocks, the revised lot size will decline, but the new size will not be a multiple of the existing lot. The remaining 151 stocks in the derivatives segment will continue with the current lot size.
Likewise, on the BSE, 43 stocks will witness an increase in lot size and 5 stocks will see a reduction. In addition, 1 stock will have its lot size cut, although the revised size will not be in the multiple of the current lot. The lot size of the remaining 150 stocks will remain unchanged.
It must be noted that HUDCO, Piramal Pharma, Tata Technologies and Torrent Power are not part of this revision, as these stocks are being excluded from the F&O segment. Hence, April will be the last available expiry for trading in these contracts.
As for implementation, the revised lot sizes will take effect from the July series on the NSE, whereas on the BSE, the changes will come into force from the May series.
These revisions are part of a periodic exercise aimed at keeping the contract value in the ₹5-10 lakh range. Therefore, stocks whose contract value has moved above ₹10 lakh will see a reduction in lot size, while those that have fallen below ₹5 lakh will undergo an upward revision.
