A convertible security is a financial instrument whose holder has the right to convert it into another security of the same issuer. Most convertible securities are convertible bonds or preferred stocks that pay regular interest and can be converted into shares of the issuer's common stock. Convertible securities typically include other embedded options, such as call or put options. Consequently, determining the value of convertible securities can be a complex exercise.[1] The complex valuation issue may attract specialized professional investors, including arbitrageurs and hedge funds who try to exploit disparities in the relationship between the price of the convertible security and the underlying common stock.[2]
