Alex Mathew, head - research centre, Geojit Financial Services said, ``The overall trend for the market remains dull, ahead of F&O expiry. The rollover figures were not so encouraging. Nifty rollover was around 48% which is too low comparing with the previous rollovers. The low rollover is partly due to inflation figure, which is expected to be above 12.85%.``

``The Nifty futures volumes were also too low, may be participants are expecting subdued trend to continue for some more time. Nifty has support at 4,240, 4,168 levels. Resistance at 4,398 and 4,415. A break above or below can give a direction,`` he said.

``As far as small investors are concerned it is safe to increase cash positions at this juncture. Carry over of long positions is also not advisable. Shorting mini futures are helpful for hedging portfolios,`` he advised.
