Ability to predict the future provided by use of book-to-market ratio can be used to making relevant decision and show whole estimation about real value of company's shares at a given point in time[1].
The meaning of Book-to-market-ratio
Many of economists or other people making actions in the area of finance over the years looked for a tool or method to predict financial future of a company. Bunch of experts conduct a researches to find a relevant variable, which may become proper base to predict a stock return by analize past actions of company's historical cost or estimating account value[2]. In 1992 in literature there was defined a two different variables by Fama and French, which can be described as market equity (ME) and book equity (BE). What is more, a few years later following studies allow to detect fact, that these variables are also sensitive to a size of analyzing company[3].
Book-to-market ratio, based on previous studies, can be framed in following formula[4]:
In the cited formula, book-to-market ratio is a result of comparing book equity (BE) to market equity (ME). When book-to-market ratio is low, what can be expected when book equity is much lower than market equity, it means that market value of the share is overvalued[5]. Similarly when it turns out that book equity is much higher than market equity, shares are undervalued. Whole use of tool refers to real value of share at a given point in time. Using a ratio to change the price results in correcting underpriced or overpriced value and allows to implement real price to the market[6][7]. However, BE/ME is only a tool refers to checking expected returns, which can fill the economic void but unfortunately, it cannot show complete economical situation and this is only a part of complicated analysis. Despite this fact, it is worthy to use for share price establishment and future actions[8].
