Many might feel that this bull run is going to end soon however beware that it has just started. There might be some corrections in the market in the coming weeks however after that a new high should be made. The market is going to be in bull run for next couple of years seeing Indian position in the world market. Notice that FIIs are keep investing for last several weeks and they are going to be here for long term.
So whenever dip comes, invest in quality stocks and keep it for long term. "Invest in India, India ka bhav badne wala hai" hahaha.
Do not get lured with the junk stocks making 52 weeks high and going to upper circuit daily, just ignore them, they are to trap a normal retailers like us. Invest in known companies with good past track record and good potential for future in business, and good and known promoter.
