Dont you remember, the news, the BEST quarter in 3 years, GST, broad based buying, and so on.
we are carried away with doubt and surprise,then question upon questions, when we are not able to move with the market. So be aware of the main trend.
BN or any other index or market followed the same pattern many a time in the past. see the chart for early 2016 to sep 2016.
I expect 22900 next week that is our monthly resistance area. further we will see on weekly closing....For monthly target even 23000 also possible.
I was away and am not available in the market hours. :D
