Maetryx here,
Do yourself a huge favor and buy this
book. In spite of the cheesy title,
The Only Investment Guide You'll Ever Need by Andrew Tobias is the best beginner's book period.
Because it does more than answer your stock market questions: it forces you to decide *if* you should be buying and selling stocks at all, or if there are a ton of other *common sense* strategies you should employ first i.e. pay off your high interest credit card debt first.
Now for some answers to your actual questions.
A corporation is a "taxable entity". To the U.S. government (and state governments) all individuals and corporations are the same thing: IRS customers. Corporations are incorporated (literally made into a body) by filing appropriate paperwork with appropriate agencies. See an attorney, I have no idea.
A public corporation, run by a board of directors (a bunch of guys) and a CEO (the biggest guy) may have a meeting and say, "Shit. We don't have enough money to buy a new building, put an ad on the SuperBowl XXXX, give ourselves outlandish salaries, and hire a personal intern for each member of this board!" So, they get together with some attorneys and accountants and create a zillion shares. With approval from the SEC (Securities and Exchange Commission) they sell their shares on the open market i.e. Wall Street.
What you are buying is a small part of that corporation. The board of directors, under the leadership of the Cheif Executive Officer, is *your* employees now. And a lot of other people. They are responsibe to *you* to make sure they are making money. Becuase that's why you bought their stock. Buy enough stock in the company, and you can put yourself on the board of directors, or vote to kick the current CEO out the window.
There are two basic ways to make money on a stock, or rather, two reasons you would buy a stock. The best reason to buy a stock is because every quarter (3 months) the corporation adds up its total sales, subtracts off total expenses, and has a net profit. Guess what? That profit belongs to (drum roll) THE STOCK HOLDERS!!! So they pay a dividend. They take the $47.00 they made that quarter and divide it by the zillion stocks they issued, and send $0.00001 to you for every stock you own.
The other way to make money on a stock is to look at the 52-week hi's and lo's and say to yourself "Shit! This stock was selling for $120 a share 40 weeks ago, and now it's selling for $0.375 a share!" And you happen to know that the company is NOT going to go bankrupt and in fact, is recovering from some very bad times or whatever, or you just know that MCI Telecom is about to buy that company for a bazillion gazillion dollars or whatever. So you speculate. And you buy it even though they haven't paid out a dividend since the A-Team was blasting across the boob tube in hi-fi camouflage.
Where do you buy a stock? It's not like you can go to Gay-Mart or E-Gay or Gay'n Pak. You go to a stock broker. The best, cheapest stock brokers in the world are online stock brokerages like Ameritrade, Etrade, Datek and the like.
Because buying and selling stocks costs money COMING and GOING. Most online brokerages charge about $10 to $8 per trade. Charles Schwabb was still charging $29.95 per trade a couple years ago, those morons, so I left and I personally use
Ameritrade. It's $8 a trade.
The basic strategy is, and always will be,
BUY LOW, SELL HIGH. Add to that, Buy What You Know. For example, Anandtech readers are some of the worlds savviest tech folks. They are probably well suited for buying technology stocks. But probably not so good at energy stocks or other industries.
But seriously, read that book first. You can probably get it at a library.
