im tired of beating this dead horse...last posting im doing on this topic so heres some more documentation
"
(NYSE) Rule 118 and American Stock Exchange (AMEX) Rule 132, which dictate how open ("good-till-canceled") limit orders to buy and sell stock are handled on ex-days. On both exchanges, open limit orders to buy stock must be reduced by the cash dividend amount on ex-cash dividend days. If the resulting price is not a multiple of an eighth of a dollar, then an ex-cash dividend limit buy order price is reduced to the next lower eighth. Limit orders to sell are not changed by the ex-cash dividend event.(5) In addition, patterns in ex-day abnormal returns are shown to arise because trading is done at discrete price intervals (normally $1/8 for stocks selling above one dollar per share), while cash and stock dividends paid per share are usually not multiples of eighths.
On ex-stock distribution days, NYSE Rule 118 and AMEX Rule 132 require a specialist to reduce all outstanding limit buy orders. The new limit order price equals the original limit order price divided by 100% plus the percentage value of the stock distribution. For example, a limit order price will be divided by 101% when there is a one percent stock dividend. If the resulting price is not a multiple of an eighth of a dollar, then the limit buy price is reduced to the next lower eighth. Outstanding limit sell orders for NYSE stocks are not reduced; however, AMEX limit sell order prices are reduced by 100% plus the percentage value of the stock distribution, and rounded down if necessary, when a stock trades ex-distribution
case closed..if you think your getting something extra when you get a dividend that you didnt have before the dividend then keep believing it .
if you believe the dividend is just a wash ,nothing gained or lost from the dividend payment its self then you are correct....there may be associated action in the market related to the dividend payment moving the stock up or down but thats not what we are refering to in this discussion..
its the dropping of all the offers by the dividend amount that translates into the stock price dropping by the dividend amount......
