For all the investors who have been focussing on the midcap segment, this was a week of reality check. The way midcap stock tumbled and the way market breadth panned out it was just a reminder of two things, never ignore valuations and secondly however good the stock might be when the correction takes place, even the best of the stocks can decline sharply. For all those investors whose portfolio is titled in favor of the mid-caps need to do two things in current market conditions. First, don't extrapolate what has happened in the last one quarter to the mid caps stocks. The reason: there might be some change in the ways the flows are coming to midcap funds due to recent SEBI advisory through AMFI to fund houses. Second, which is more important, be careful when taking fresh exposure to this segment of the market and apply checks and balances.
