BSE stock price can crash 19% as Sebi okays expiry day switch

Technical chart shows that BSE stock is likely to trade with a negative bias as long as it sustains below ₹2,924 levels. Here are the key support levels to track.

Shares of the Bombay Stock Exchange (BSE), listed on the National Stock Exchange (NSE) declined up to 6.2 per cent in intra-day deals on Wednesday to a low of ₹2,500 after the Securities Exchange Board of India (Sebi) approved to switch the derivatives expiry day of both the stock exchanges.  Derivatives contracts on the NSE will now expire on Tuesdays from September onwards, moving from the current Thursday expiry. Conversely, BSE contracts will expire on Thursdays, shifting from the current Tuesday expiry.  In May, the market regulator issued a circular restricting expiries to just two days a week and asked each exchange to select one. The current expiry days will remain in effect until August 31. Analysts believe BSE could cede some market share owing to the shift in expiry days.
