# Market Cap vs. Stock Price: Why a High Share Price Isn't 'Expensive'

> A $500 stock isn't pricier than a $50 stock — what matters is total market cap. Here's why share price alone tells you almost nothing about size.

A high share price does not make a stock "expensive," and a low one does not make it "cheap." On its
own, a share price tells you almost nothing about a company's size or value. The number that actually
measures size is [market capitalization](https://www.marketcaplens.com/learn/what-is-market-capitalization): the share price
multiplied by the number of shares.

**Key takeaways**

- Share price alone is not a measure of size or value.
- Market cap (price × shares) is what tells you how big a company is.
- Two companies worth the same can have very different share prices.
- Stock splits change the price and share count but never the market cap.

## Why share price is arbitrary

A share price is just a company's total equity value divided by however many shares happen to exist.
Because the share count is a choice the company makes, two businesses worth exactly the same can trade
at completely different prices:

| Company | Share price | Shares outstanding | Market cap |
| --- | --- | --- | --- |
| HighPrice Co. | $500 | 2 billion | $1 trillion |
| ManyShares Co. | $50 | 20 billion | $1 trillion |

ManyShares Co.'s shares cost a tenth of HighPrice Co.'s, yet the two businesses are worth the same.
The "$50 stock" is not the bargain it might look like. (Broker apps still lead with share price because
that's what you click to trade — size is a separate column.)

## How stock splits prove the point

A [stock split](https://www.marketcaplens.com/learn/what-changes-market-cap) is the cleanest example. Imagine a company at **$1,000**
a share with **1 billion** shares ($1 trillion market cap). After a **10-for-1** split it trades near
**$100** with **10 billion** shares — still **$1 trillion**. Nothing about the business changed; the
company is simply sliced into more pieces.

## Why cheap-looking stocks can mislead

The reverse trap is assuming a very low price signals a bargain. Many low-priced stocks belong to small
companies, often [micro-caps](https://www.marketcaplens.com/learn/market-cap-size-tiers), that can be thinly traded and volatile.
The low price usually reflects the small size and higher risk, not a discount.

## What to compare instead

When you size up companies, look at market cap rather than the price of a single share. That is why the
[MarketCapLens ranking](https://www.marketcaplens.com/) is ordered by market cap: it puts every company on the same footing no
matter how many shares each has chosen to issue. For the mechanics of the number itself, start with

## Frequently asked questions

### Does a higher share price mean a company is bigger?

Not necessarily. A company sets its share price partly by choosing how many shares to issue, so price alone says nothing about size. Market cap, which is price times shares, is the measure of size.

### Does a stock split make a stock cheaper?

Not in any real sense. A split gives you more shares at a proportionally lower price, and the company's total market cap is unchanged.
