Please explain the relationship between dividend amount, stock price, and option value?
Regarding:   1) What's the point of paying a dividend if the stock price automatically decreases? Don't the shareholders just break even?   As dividends distribution dates and amounts are announced in advance, probably the stock price will rise of the same amount of the divident before the day of distribution. If I know that stock share A's value is y and the dividend announced is x, I would be willing to buy shares of A for anything > y and < than x+y before the distribution.So, arbitrageurs probably would take the price to x+y before the dividend distribution, and then after the dividend distribution the price will fall back to y.
