The BMO stock split is a rise in the number of outstanding shares by issuing more stocks to current shareholders. For example, two stocks are provided for each stock held by a shareholder in a 3-for-1 shares split.
A stock split is usually a good investment index, signaling the bank's stock price is rising. On the other side, a share split may not affect the attractiveness of securities in the future as opposed to fundamental factors.
The Bank of Montreal managed a two-for-one stock split on March 1, 2001 (BMO stock split history).
