I wondered the same thing and I hope it happens. I use share builder for my trading it's not the best but it does the job. My question is it automatically reinvests dividend monies unless you check a box to say not to. I never checked it when I started because Siri did not have a dividend. I wonder if any other stock trading accounts do the same and will just automatically reinvest that money tomorrow (forgot about it) because they thought the same as me? My regular dividend stocks I make sure to adjust it the way I want!!
