<prompt> Human: Is it really as simple as registering for a website like e-trade, purchasing some stock for a particular company using my credit card, watching the price jump up and down for awhile, and then selling it back using e-trade and they deposit the money in my account? Is there a better way to go about it?EDIT: Thanks for all of the informative responses! Upvotes all around!  <response>: There is a better way. Dont use e-trade. heh.-- e-trade member.In actuality, thats really all there is to it. Open up a brokerage account with whoever. Link it to a bank account and transfer money into your account. Pick whatever stock you want to gamble with and purchase it. Ride the wave and sell when you see fit. Transfer the money from your brokerage back to your bank.
