Day trading = trading stocks or bonds (securities) with the intention of selling them very quickly (intra day) to make a quick profit without any care as to the long term value or dividend paid on that security.

Options = the right to buy someting (securities) at a certain price.

For example: If I buy a stock option of Yahoo!, I might pay $10.00 for the right to buy it at $25.00. My hope is that the stock goes to $100 dollar. Then, I cash in my options, pay $25.00 for each $100 share, turn around and sell my $100 share and profit $75.00 for each share.

The problem is that if the stock goes DOWN, below $25.00, then I either hold on (I have 10 years typically to hold it before I am forced to sell) or I sell it at a LOSS.

If this is the best answer, please vote it the best answer. Thanks!

Day trading is buying and selling of a particular stock many times throughout the day. Throughout the day, a stock price may change due to several things, such as volume (others buying or selling). Day traders try to take advantage of this by buying the stock on the low swings, and selling it on the high swings. It usually takes a lot of money to do this in order to make it worth your while. Day traders often do this with several stocks at once.

Most on line brokers require a minimum cash account of around ten thousand dollars for you to day trade. I can't remember the rules exactly, but Ameritrade, considers day trading as buying or selling of the same stock within a couple days. And if you have two or three instances of this, they classify you as a day trader.

Stock options are something that employers offer to make a job more desirable. Usually offering company stock on top of their normal pay. Having stock in a company you work for also makes you care more about your company.
