The stock is already at a 52 week low and has fallen from Rrs.141 to Rs.61. Most private banks have been de-rated after the crisis in Yes Bank as most investors are worried about the health of these banks. Also Karnataka Bank was seeing higher value after there were talks about a takeover. However, now that appears to be unlikely after the episode of Yes Bank. Hence you need to be careful. Most of these banks used to enjoy high ROE at one point of time. But bad assets have taken their toll and that makes these banks fairly dangerous to be invested in. You must be cautious while investing in such banks as liquidity is quite a constraint and cost of funds is going up sharply. Position your trade accordingly.
