Let's say that the Dodgeball Supply Co. (ticker: WHAPP), trading at $50 per share, has reported $2.50 per share in earnings for the last year, and pays a $1.50 annual dividend. If it splits 2-for-1, the number of shares outstanding will suddenly double and will trade around $25 each. (Shareholders will own twice as many shares valued at about half their pre-split price). The company's previous earnings per share (EPS) of $2.50 will also be halved, to $1.25, and its annual dividend will be adjusted downward, from $1.50 to $0.75.
If the stock's fair value had been $60 pre-split, it will be about $30 post-split. Its price-to-earnings ratio shouldn't change, as both the price and the EPS components have decreased in the same proportion. Its total market value is also unchanged.
