The sample used is purposive sampling based on certain criteria, namely the troubled shares owned PT. Jiwasraya for the 2017-2020 period.

There are 23 out of 24 stocks that provide a return below the expected return such as the BNBR stock return, namely (0) with an expected return (0,00387) which means that the return obtained by PT. Jiwasraya is not as expected.
