What is a Stock?
A small piece of ownership in a company.
Why it matters
A share of stock is a slice of ownership in a real business. That one fact changes how you see the whole market. A stock is not a lottery ticket or a number that blinks on a screen. It is a legal claim on a company's profits and assets, and buying one makes you a part-owner of the business behind it.
This is the foundation every other idea rests on. Dividends, share prices, and the valuation ratios you will meet later only make sense once you see a share for what it is: a small, countable piece of a company that earns and grows over time.
An everyday way to picture it
Picture a company as a single large pizza, cut into a fixed number of slices. Each slice is one share. The more slices you own, the more of the pizza, and the more of the company, is yours. If the pizza becomes more popular and people will pay more for it, your slice is worth more. If it burns, meaning the business does badly, your slice is worth less.
The number of slices is fixed, so each one stands for a real, countable fraction of the whole. Owning 100 slices of a 1,000-slice pizza means you own exactly one tenth of it, no more and no less. That simple ratio is your ownership stake.
What a share actually gives you
When you own a share, you own a genuine piece of the company, and that piece comes with real rights. You are not lending the company money or betting on its price. You are an owner.
| What you hold | What it means for you |
|---|---|
| A claim on profits | The company can hand part of its earnings to owners as dividends |
| A claim on assets | If the company is ever sold or wound up, owners have a claim on what is left after debts are paid |
| A vote | Common shareholders can vote on big decisions, such as electing the board of directors |
| Upside, and downside | Your shares gain value as the business grows, and lose value when it struggles |
See it for yourself: how much do you own?
Set the total shares a company has issued and how many you hold, and watch your ownership stake.
Why companies issue shares
A company sells shares to raise money to grow, without taking on debt it has to repay. Say FreshJuice Ltd. wants to open new stores. Instead of borrowing, it issues fresh shares to investors. The investors provide the cash, the company expands, and everyone shares in the result if it works.
When a company issues brand new shares, the pizza is cut into more slices, so each existing slice becomes a smaller fraction of the whole. That is called dilution. Your number of shares does not change, but your percentage does, unless you buy more. Dilution is not automatically bad. A smaller slice of a much larger business can be worth more than a larger slice of a small one, because the company now has cash to grow.

Issue new shares and watch your ownership percentage change, even though the number of shares you hold stays the same.
Why share prices move
A share price is simply what buyers and sellers agree on right now. It moves up and down every day for three broad reasons.
| What moves the price | How it works |
|---|---|
| Company performance | Rising profits tend to lift the price over time. This is the strongest long-run driver. |
| Investor sentiment | Hope and fear push prices around in the short term, often far from what the business is really worth. |
| The wider world | Interest rates, government policy, and global events all shift what investors will pay. |
Underneath it all sits one idea. A price reflects what the market expects the company to earn in the future. When investors believe a company will earn more, they pay more for its shares today.

Common and preferred shares
Not every share is the same. Two kinds turn up most often, and as a beginner you will deal almost entirely with the first.
| Type | What it means | In practice |
|---|---|---|
| Common stock | What most people buy. Gives ownership and voting rights. | You receive dividends and can vote at company meetings. |
| Preferred stock | Behaves more like fixed income. Gets priority for dividends but usually no vote. | Steadier payouts, but less of the upside if the company grows. |
Worked example: FreshJuice Ltd.
Let us make it concrete. FreshJuice Ltd. has issued 1,000 shares in total, and you buy 100 of them. Here is exactly what that ownership is worth.
| Step | Working | Result |
|---|---|---|
| Total shares | What FreshJuice has issued | 1,000 shares |
| Your shares | What you bought | 100 shares |
| Your ownership | 100 ÷ 1,000 | 10 percent |
| Profit last year | What the business earned | ₹5,00,000 |
| Your share of profit | 10 percent of ₹5,00,000 | ₹50,000 |
Owning 100 of FreshJuice's 1,000 shares makes you a one-tenth owner of a real business. You have a claim on one tenth of its profits and one tenth of its growth, all from your phone. If the company grows and becomes worth more, so does your stake. If it struggles, your stake falls with it. That two-way link is exactly what a stock is.
Remember this
| Concept | Meaning |
|---|---|
| Stock | A small piece of ownership in a company |
| Shareholder | A person who owns one or more shares |
| Company issues stock | To raise money for business growth |
| Stock price | Moves with company performance and investor mood |
| Owning stock | Means sharing in the profits, the risks, and the decisions |
In short: when you buy a stock, you become a part-owner of a company, not just a trader of its price. Your return depends on how well the business performs over the years you hold it.
