What a stock actually is

Ownership, not a bet slip

If you are here because the 9-to-5 feels like a trap, start with the unsexy fact: a stock is a share of a real company. If it has 100 shares and you hold 10, you own 10%. That is a claim on whatever the business earns over time — not a promise the price goes up tomorrow, and not a ticket out of a paycheck.

Companies sell shares to raise money they can use to hire, build, or pay down debt. In return, shareholders take on the risk that the business does poorly — and the chance that it does well. The opportunity is real. Treating it like a scratch-off is how first accounts die.

Cash from the business, without selling

Some companies send shareholders a slice of earnings in cash. That payment is a dividend. You keep the shares. Cash hits the account. That is the buy-and-hold mechanic in one sentence: own the business, and if it pays, you get paid without staking a sale.

Not every stock does this. Fast-growing companies often keep the cash to hire and build. Mature businesses are more likely to pay. Yield is last year's dividend divided by today's price — a ratio, not a promise. A 4% yield on a $50 stock is $2 a year per share. The company can cut it, skip it, or raise it. A dividend is not a paycheck and it is not risk-free.

The price often drops by about the dividend on the morning the stock goes 'ex-dividend.' You did not get free money. You got a cash slice of a slightly cheaper share. Reinvesting those payments (a DRIP) buys more shares automatically. That compounds if the business lasts. It does not rescue a bad company or a position that is too big for the rent.

Price is an agreement

The quoted price is simply the last price two people agreed on. It is not an official appraisal. If no one wants to sell at your bid, you do not own the shares yet — no matter what a chart says.

That last print moves in ticks: the smallest amount the price is allowed to change. For most U.S. stocks that increment is $0.01. If the last trade was $50.00, the next one can be $50.01 (an uptick) or $49.99 (a downtick) — not $50.003.

The ticker is the company's short name on the screen (AAPL). The tick is the move. Market value (often called market cap) is share price times the number of shares. A $50 stock with 2 million shares is a $100 million company. A $500 stock with 10,000 shares is a $5 million company. Price per share alone tells you almost nothing.

Why prices move

Prices move when buyers and sellers change their minds about the future of the business — earnings, competition, interest rates, or simply mood. Over long stretches, a stock tends to follow the company's results. Over short stretches, it can do almost anything.

This course treats trading as a skill of process: how orders work, how to size risk, how to read a quote. Attitude plus that education is the realistic path. It is not a method for picking winners or quitting on Monday.
