Abstract: TUsing the stock index data of financial sector spanned from January 2, 2009 to December 31, 2014, this study examines the effects of some policies on stock returns and volatility in Vietnamese stock market. The empirical results of EGARCH model reveal thattwo policies, namely, M&A and VAMC have an significantly positive impact on stock returns but they do not represent any effects on stock volatility. The third policy, regulatory reform, does not show any affection on stock return but it has an impact on the stock volatility.It implies thatinvestors should adjust and alter their portfolio accordingly when changing policies. Besides,policymaker needs to know when they should prioritize which policy to be issued because some policies sometimes can hurt the stock market if the stock market is efficient.
