Reliance Industries 2008 – 11 crore fine Raj Rajaretnam in 2011– 600 crore Rajat Gupta (2011) -130 crore Mathew Marthoma in crore Powered by undisclosed price sensitive insider information. Raise question about the trustworthiness and effectiveness of legal framework and the market as a whole
INFORMATION ASYMMETRY A state of disparity between Insiders and Outsiders in possession of information. He et. al (2011) It can’t be eliminated! It can only be reduced and check illegal usage. Aboody and Lev (2000) Insider trading backed by undisclosed price sensitive information is a by product of information asymmetry. Frankel and Li (2004) It is difficult to identify an illegal insider trade. Frankel and Li (2004)
REVIEW OF LITERATURE Information asymmetry affects the trustworthiness of market. Akerlof (1970) Informational superiority of insiders for market gains. Seyhun (1986), Seyhun (1992), Ke et, al, (2003), Frankel and Li (2004) and Cohen et, al, (2012 Core insider trades are excessively profitable. Frankel and Li(2004) Analyst follow up, media coverage and R&D investment are contributing to high information asymmetry. Frankel and Li (2004)
REVIEW OF LITERATURE Insider trading profits are reaped around six months after the trade with highest profitability for core insiders. Seyhun (1998) Legal frameworks are a failure in checking the abnormal profitability of insider trade in US. Seyhun (1992) 7% of total insider trades are excessively rewarded in the US market. Seyhun (1992)
DATA AND VARIABLES Insider’s trading dates, No of insider trades. Dividend adjusted buy and hold return. Book value, market cap, market return and 3M T-bill rate for calculation of Fama & French factors. Analysis ranges from January 2005 to December 2013 Data collected from Bloomberg.
METHODOLOGY Profitability of insider trading – proxy for information asymmetry. Frankel and Li (2004) Six month trade window. Seyhun (1998) Comparison of time-specific common expected return with actual insider return. Frankel and Li (2004) Dividend adjusted buy & hold return = [(P 1 – P 0 ) + D]/P 0 Fama and French(1993) model to calculate expected return. [R = Rf + β(Rm – Rf) + βHML + βSMB]
METHODOLOGY Portfolios created – SL/SM/SH/BL/BM/BH Fama and French (1993) All insiders were included. Based on SEBI definition Profitable insider trades. Frankel and Li (2004) For Purchase:- Actual insider return is higher than common expected return. For Sales:- Common expected return is higher than actual insider return. Insider trading trend of a month was decided based on Net purchase. Frankel and Li (2004) Net purchase = Total number of insider purchase - Total number of insider sales.

THE STATE OF INFORMATION ASYMMETRY IN INDIA The level of information asymmetry in India proxied by profitability of insider trade is alarmingly vulnerable. Mid cap companies followed by large cap and small cap companies are mostly affected by the problem of information asymmetry. Size of Companies Excess profit firm- months for Purchase Excess profit firm- months for Sale Excess profit firm- months in Aggregate Small Cap 55.42%40.28%49.74% Mid Cap 55.02%55.74%55.43% Large Cap 52.33%51.06%51.46% Total Companies 54.25%49.02%52.46%
SUMMARY RESULT
CONCLUSION Evidence shows that level of information asymmetry in Indian equity market is very high. About 52.46% of insider trade firm-months are excessively profitable. Purchase insider transactions are more profitable than sales insider transactions. Mid cap companies followed by large cap and small cap companies are very vulnerable to this market imperfection. It also points to the deficiency of the existing legal frame work and need for strong and effective laws.
