For all those investors whose portfolio is titled in favour 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. Second, which is more important, be careful when taking fresh exposure to this segment of the market and apply checks and balances when investing and even after that be ready for some drawdown in the value of the stocks. How does one put checks and balances? Simple, have a look at fundamentals and it is not very tough, having a look at some of the critical ratios like ROE and ROCE would help in avoiding silly mistakes which are common in bullish markets.
