The efficient market hypothesis (EMH) was promoted by Eugene Fama in the 1960. In his classic paper Fama (1970) defined market in which prices always fully reflect available information as “efficient”.While

According to USFDA, a combination product is one composed of any combination of a drug and device; biological product and device; drug and biological product

this definition reflects the main idea of the EMH it might be extended to explain the underlying assumption. For example Malkiel (1992) proposed the following definition:

A capital market is said to be ef

Examples of combination products may in

As it follows from the Malkiel (1992) definition if the market is efficient the company market value should be an unbiased estimate of the true value. Nevertheless it is important
