Go to Yahoo Interactive charts (column on left) pull up the 2 yr for VZ. activate the dividends in the Events box above.
You will see the price rise just before x-div to a high point. People are "buying the dividend". Then there is usually a quick drop as sellers take their $. Sellers want the highest $ and don't care about the div. Sellers typically wait untill x-div to sell for the best price.
Usually somewhere midpoint between dividends there is a low point - often the best time to buy.
Remember ex-div means the stock trades EX (without) the dividend on that day. You must purchase the day before to receive the dividend. The stock drops the amount of the dividend on ex-div day and the market takes over from there.
Good luck investing.
"The stock drops the amount of the dividend on ex-div day" - always found this interesting. Who made up this rule? Why not let the market decide where it will trade best on buying and selling. Maybe it should trade up as a dividend makes it more "valuable".
