The Security and Exchange Board of India, SEBI is considering framing a policy for the stock exchanges to go through a stress test. The test will help these exchanges to prepare them for handling crash-like situations, where a sharp plunge in some stocks leads to across-the-board panic sale. Official sources said, the proposed stress test would prepare the bourses for handling situations where any sharp fall in share prices of one stock, possibly because of a freak or wrongly-entered trade order, can result in panic-selling by investors. In addition to freak trades, the stress test would also measure the stock exchange's preparedness for situations when any sharp plunge in any one stock, due to reasons like negative news flows such as frauds and scams, can affect the broader market sentiment. The Indian market already has circuits in place to avoid any large-scale fall. These circuits come into effect at a relatively high level of at least 10 per cent movement in the case of indices. There are no circuits at all for blue chip stocks.
