Stock price effect of high-yield debt issues

This paper investigates the common stock price reaction at the announcement of the issuance of high-yield straight debt. The two-day announcement period abnormal returns are not different from zero for the 164 bond issues in the sample. No difference is found between announcement period abnormal returns of firms with bonds that default and firms with bonds that do not default. Results from statistical tests indicate that the announcement period abnormal returns are not explained by issuance year, bond-rate class, underwriter, issuance size, takeover activity or prior high-yield debt issuance experience. The findings are not consistent with the models by Miller and Rock (1985), Jensen (1986), Myers and Majluf (1984) and Krasker (1986). However, results indicate that existing stockholders are not harmed or helped by the issuance of the high-yield straight debt.
