From January 1, 2016, shares of four companies - Jet Airways, Godrej Consumer Products, Container Corporation and Torrent Pharma – will be the part of the derivatives segment on the NSE. Jet Airways, which was removed from the F&O segment in 2012 is making a re-entery, thanks to the sharp rise in its share price. Though all these shares witnessed higher activity on Thursday, the actual inclusion would pep up volumes further.
