Are there any reasons for you sensing such downside Siddhant sir? Aside from factors mentioned by ST ji.
The bull run was quite long this time. In fact, some consider that it's been running since 2009!
If you look at many banking/finance sector companies chart, you will see that some are going up on steep hill which defies gravity! Combine this with higher PE ratio for Nifty, world market in turmoil, political situation between US/China/Saudi/Brexit, USD/INR there are no good news anywhere to aid the bull .
Few words you will keep hearing soon in market 'running out of steam', 'what goes up has to come down'..
just my 2 cents!
You will get lots of buying opportunities soon, but just remember to do SIP for stocks picking like S_T da suggested. I did mistake in 2008 by investing all backup fund after my portfolio went 10% down and was left with negative portfolio for 3 years. And remember what's lucrative now may become penny stock within 1 year. Suzlon, RCOM, Punj Lloyd, Unitech, Idea, DLF, were once blue chip stocks.
