How much $$$ can I get for buying one facebook share?

Well, if you purchased the stock first thing friday morning and did not sell, you would have now earned 23-cents. Monday is a new day, you might gain money or lose money.

That is not how stock works. You can use some of the tools that you find on Yahoo Finance to watch charts and see if you can get an idea of where the stock will go, but everyone will basically have their own ideas and what you will be able to get for one share of stock is only what someone will be willing to pay you for it. Investors, even regular investors usually deal with a hundred shares as a minimum. You would have a problem finding someone who would sell you one share of stock because it almost screams that you do not know what your doing. Since Facebook is an IPO, that means there is no history of its trading other than friday May 18th. Many investors thought the stock would pop, that is go up high very fast, and they thought they could make a bunch of fast money. When it didn't right off the bat, they got scared and started selling. the stock therefore, went up to around S 42 a share during the day, but by closing it was around 38 which was about the opening price. If you believe strongly in FB and are willing to risk 40 bucks or so, buy a share or two. It could end up being another Google or Apple and you could end up selling it for $ 500 or it could end up being worth $ 5 in a couple of years when something comes along that we never thought of that will replace it. The ticker symbol for Facebook is FB; for Apple it is AAPL; for McDonald's it is MCD; and for Microsoft it is MSFT. Look up charts for a year. Try to buy when the chart line is low, not when it is high.

All depends on the stock market
