Bandhan Bk is has made huge business in Covid era when other banks where reluctant to finance small business and also Housing loans have increased for Bandhan Bank. I generally don't look into the Fundamentals but it can be an underlining factor. My picks are generally based on Open interest and Price action combination wherein Bandhan Bk also fits in. 280 is strong support as per open interest data. This view will be invalidated if it trades below 280 levels.
