This is trend follow or follow crowd. If there no news flow options create direction to Nifty.
Other factors like long weekend holidays whether nifty is at peak, or PCR is above 1.6 may lead to profit booking.
For this week we have good news on many fronts.
Due to reduction in excise for Fuel inflation may not raise so there may be rate cut in December.
Trade deficit is at seven months low. These data indicates economy has bottomed in Q1FY18 itself.
This year there is plenty of rains. So food inflation also will not rise much.
FII added more long contracts on Nifty Futures.
Their net long positions on Nifty is rising from 50% on last expiry to 59%.
We may see profit booking else there is no negative signals.
Whenever Nifty Scales all time high our media and Analyst talk about valuation and liquidity driven rally
When Nifty was going below 9700 every one was telling it will go to 9200.
But if you at ground level thing are positive. Still people think about DEMO and GST in negative tone. But they ( DEMO GST) were the reason for today’s All time high.
