But first, let's look at some answers I've found unsatisfying.

## Unsatisfying answer 1: "ownership"
13+
One unsatisfying answer goes something like this:
1314

1415
> A share (also known as a stock) represents ownership of a piece of a company.
1516
> For example, if you own 50% of a company's shares, you own 50% of the company.
1617
> When the company makes a profit, more people want to own it, so they buy its shares, which causes their price to rise.

But a share just feels like a piece of paper with the company's logo on it. How can I use it to make money? I don't feel like a real owner of the company.

Why should its profits affect the value of my piece of paper?

## Unsatisfying answer 2: "self-fulfilling prophecy"
23+
Another unsatisfying answer goes something like this:
2324

2425
> Pieces of paper, like Dogecoin, can have a price.
2526
> When people believe its price will rise, they buy, hoping to sell later.
2627
> But the wave of people buying _is_ what makes the price rise (by increasing demand and reducing supply).
2728

2829
> This self-fulfilling prophecy is one mechanism that links share price to company performance.

> The company does well, so people believe its share price will rise, due to past experience. Therefore, they all buy it, which causes the price to actually rise, reinforcing their belief.

Sure, I can see self-fulfilling prophecies influcencing a share's price, but I doubt that's the only mechanism at play.

## What makes shares more than pieces of paper
3739

3840
The first question we should ask is what do shares have that pieces of paper don't? These things:
3941

40-
- **Dividends**. If a company decides on a dividend of $10, that means it will pay shareholders $10 per year for each share they hold. So if you hold 15 shares, the company will pay you $150 a year.

- **Dividends**. Dividends are payments made by a company to its shareholders.

- **Share buybacks**. A company can decide to buy its own shares back from the open market, making them essentially disappear.

- **IPOs (initial public offerings)**. A company can decide to create new shares out of thin air and sell them.

- **Voting rights**. For each share you own, you get one vote on shareholder matters. You can elect board members. Board members are the people who control when the company does dividends, share buybacks, and IPOs. Board members also hire executives to run the company.

So how do these things affect share price?

## Majority shareholder incentives
5155

5256
Imagine you own 51% of a company's shares.
5357
As a greedy human, how can you use this to make money?
5458
Well, you have 51% of the vote, so you can control the board of directors by electing members that will do what you want.

You could tell the board members to give you a high salary using company revenue.
57-
But high salaries are heavily taxed.

You can instead tell the board members to spend company revenue on dividends, which aren't taxed as heavily.

6064
Since you own 51% of the shares, you'll get 51% of the dividends.

62-
A method that's taxed even less is telling board members to spend company revenue on share buybacks. These decrease supply, causing share price to rise. This increases how much money you'll get when you finally decide to sell your shares.

The more profits the company generates, the more it can spend on dividends or buybacks, and the more people want to buy its shares.
65-
And that is why share price rises when a company makes a profit.
68+
You can also tell the board to hire executives that are obsessed with increasing profits to maximize how much can be spent on dividends and buybacks.

## Counterargument 1
73+
If you own 1% of a company's shares, you get 1% of the benefit of dividends and buybacks.
74+
In a way, 1% of the majority shareholder's earnings are leaking to you.

72-
> But as of 2025, some profitable companies like Amazon have never paid a dividend, and didn't do significant buybacks. So why do people still hold their shares?
76+
To maximize your earnings, you try to buy shares from companies that are likely to do sustainable dividends or buybacks.
77+
The more profit the company generates, the more it can spend on dividends or buybacks.
78+
So people try to buy shares from profitable companies.
79+
That is why share price rises when a company makes a profit.

74-
Imagine again you're a majority shareholder. You can tell the board to not give dividends or buybacks, and instead reinvest profits into expanding business.
75-
This increases future profits, allowing even larger future dividends or buybacks.
7681

77-
Investors look forward to this, so they buy shares, causing their price to rise.
78-
So the mere expectation of future dividends and buybacks is enough to raise share price.
82+
## What about companies without dividends or buybacks?
7983

84+
As of 2025, some profitable companies like Amazon have never paid a dividend, and didn't do significant buybacks. So why do people still hold their shares?

Well, imagine again you're a majority shareholder. You can tell the board to not give dividends or buybacks, and instead reinvest profits into expanding business.

So the mere expectation of future dividends and buybacks is enough to attract investors, raising share price.

## Counterargument 2
90+
On the other hand, let's say you tell the board to direct all revenue towards unsustainable dividends or buybacks.
91+
This will prevent the company from expanding, and other companies will outcompete it.
92+
This is why investors are weary of companies that have an unsustainable level of dividends or buybacks.
8293

83-
> Dividends and buybacks are leaky, meaning they give some money to non-majority shareholders. Are majority shareholders annoyed at this?
8494

85-
Quite the opposite. When a company spends money on dividends or buybacks, more people want to buy shares, which drives up their price. This benefits the majority shareholder, on top of the benefits of dividends or buybacks themselves.
95+
## Influencing public beliefs
8696

87-
My hypothesis is that the non-majority shareholders act like amplifiers of dividends and buybacks, which offsets their leakiness. But I'm not sure how much.
97+
As a majority shareholder, in addition to dividends and buybacks, you have another mechanism to make money:
98+
convincing people to buy your company's shares, which raises their price.
99+
To do this, you can tell the company to brag about rising profits.
100+
You can also convince investors that dividend and buyback levels are sustainable in the long term.

# Summary

The majority shareholders can eventually force the board to spend profits on dividends and buybacks, which are mechanisms of giving money to shareholders.

93106
The higher the profits, the more can be spent on future dividends or buybacks.
94107
This causes people to buy shares when they see profits rise, which drives up their price.
95-
But the price is also affected by social phenomena like self-fulfilling prophecies.
108+
However, if dividend or buyback levels are unsustainable, investors will be weary to buy shares.
109+
In addition price is also affected by social phenomena like self-fulfilling prophecies.
