Banknifty is consolidating from the past 4-5 months and now at very good resistance level (Black line). If this breaks then can be good signs of accumulation stage.
When compared with nifty we have seen a decent move upside and Banknifty is bit lagging from the past year due to uncertainty.
I would suggest you to long and hold Banknifty for a few months. #Positional targets 40k++ The best way to do that is buy a ETF which has no expiry and investment can be as low as 350-360 Rs.
