WHY IS THERE A PRE-open MARKET SESSION?

If a major event or announcement occurs overnight before the market opens, such events are likely to cause significant volatility the following day when the market opens. Merger and acquisition announcements, credit-rating downgrades, open offers, debt restructurings, delistings and other special events like RBI credit policy, elections etc. can have a significant impact on an investor's wealth. To stabilise this, a pre-open call auction is held to determine the best price and reduce volatility.
