Edelweiss Securities in a note said that the much anticipated regulations on taxation on investments from tax havens which comes into effect from April 1 will have some bearing on the expiry session.
"On one side, the domestic arbitrageurs are willing to roll at lower levels, on the other short roll positions of FIIs are showing reluctance to roll at current low levels. Coming back to the taxation issue, some portion of long roll positions of FIIs have been converted into cash during the series.
