BSE-Price Monitoring

Price Monitoring Cell
The function of this Cell is to detect potential market abuses at a nascent stage to reduce the ability of the market participants to unduly influence the price of the scrips traded at BSE by taking surveillance actions like reduction of circuit filters, imposition of special margin, transferring scrips on a trade-to-trade settlement basis, suspension of scrips/ members, etc.

These pro-active measures are taken based on the analysis/ processing of alerts generated based on various parameters and other inputs like news, company results, etc. The broad parameters considered for generation and analysis of alerts are price movement, top 'n' turnover, scrips traded infrequently, scrips hitting new high/ low, scrips picked up for rumour verification, etc.

The scrips picked up based on the preliminary analysis/ enquiries are forwarded to the Investigation cell for further examination/ investigation.

The detail rationale of the surveillance actions taken by BSE from time to time are as follows :

Special Margins

Special margins are imposed on such scrips which have witnessed an abnormal price/ volume movement. Special margin is imposed by BSE @ 25% or 50% or 75% as the case may be, on the client wise net outstanding purchase or sale position (or on both side).

Reduction of Circuit Filters

The circuit filters are reduced in case of illquid scrips or as a price containment measures. The circuit filters are reduced to 10 % or 5 % or 2 % as the case may be, based on the criteria decided by the Surveillance Department. No circuit filters are applicable on scrips on which derivative products are available. However, BSE imposes 10% dynamic circuit filter on these scrips to avoid punching errors, if any.

A list of equity stock on which dynamic circuit filter applied is attached.

Circuit Filter of 20 % is applicable on other scrips which are not included in the above-mentioned category.


If a scrip is shifted for settlement on Trade-to-Trade basis, selling/ buying of shares in that scrip results into giving/ taking delivery of shares at the gross level and no intra day netting off/ square off facility is permitted. The scrips which form part of the 'Z group' are compulsorily settled on a trade-to-trade basis.

As a part of Surveillance measure the Exchange transfers various scrips for settlement on a Trade-to-Trade basis. The said action is reviewed at periodic intervels (Fortnightly & Quarterly) based on market capitalization, price earnings ratio, price variation vis-à-vis the market movement, volatility, volume variation, client concentration and number of non promoter shareholders etc. The criteria for shifting scrips to/fro for settlement on T2T basis are decided jointly by the stock exchanges in consultation with SEBI and reviewed periodically. Scrips on which derivatives products are available are not considered for transfer to Trade for Trade segment.

The Fortnightly and Quarterly review calendar for the year 2014 is attached for reference.

In order to bring greater transparency and to eliminate various allegations about manner of shifting of scrips to/from the T2T segment criteria for shifting scrips to/fro Trade for Trade segment is given below :

Fortnightly Review Criteria

The detailed fortnightly review criteria for shifting of scrip to T2T segment is given below. The securities satisfying all the Criteria I, II and III shall be transferred to Trade for Trade segment.
  • Criteria I
    • PE Multiple Criteria
      • If SENSEX PE Multiple on the relevant date is in the range of 15-20 then scrips having PE greater than 30 will be considered.
      • If SENSEX PE Multiple on the relevant date is greater than 20 or less than 15 than difference will be rounded off to nearest number and same will be added subtracted from 30. However, minimum base of PE Multiple shall be 25. Accordingly scrips having PE greater than this bench mark will be considered.

    The Surveillance Department liaises with the Compliance Officers of the listed companies to obtain their comments on various price-sensitive corporate news items appearing in the media. Comments received from the companies are disseminated to the market by way of BOLT Ticker and/ or Notices on the BSE website. If the company denies the news / information, a letter is sent to the company asking them to take up the matter with the concerned media.
