If today you own 100 shares worth $500 each, on Monday you will have 400 shares worth $125 each
yes but your 100 shares had given you a dividend of $0.82 X 100= $82. However, your 400 shares going forward with same dividend rate would be $328. And 4 X $328 = $1312 which is enough to pay off your Starbucks tab for a month.
Yeah but a dividend is just dividend distribution amount divided by number of shares. If you 4x the shares but hold the dividend payment constant, everyone would be getting 1/4th of their Norma per-share dividend.
