Mmmm, only for short-term investors. The market's perception of value or price of shares may (or may not) increase, but the actual value of shares stems from the value of the underlying business which does not change one iota due to a stock split. The only instance where the "value" of a stock changes after a split is if it is traded. Why would you do that when you can realize further gains from holding a stock, particularly a bank stock, for long periods and defer taxes while doing so?
