# Insider ownership: what's a good percentage?

**Insider ownership** is the share of a company's stock held by its directors, officers, and [10%+ beneficial owners](https://insideralpha.ai/learn/what-is-a-10-percent-owner). It is the context for every [Form 4](https://insideralpha.ai/learn/sec-form-4) you read: a $1M purchase by an executive who owns nothing means something different from the same purchase by a founder adding to a 20% stake.

## Rough ranges

- **Mega-caps:** often under 1-3%. Professional management teams hold stakes that are large in dollars but small as a share of the company.
- **Mid-caps:** mid-single digits is common.
- **Small-caps and recent IPOs:** 10-40% or more is common, because founders, families, and early investors still hold large positions.

These are rough patterns, not rules, and there is no single "good" number. Compare a company with peers of the same size, then look at the **direction**: ownership rising through open-market buying, or falling through steady [selling](https://insideralpha.ai/insider-selling).

## The upside and downside of high ownership

- **Alignment** - managers who own 15% of the company feel a drawdown in their own net worth.
- **Entrenchment** - at high levels, control can shield management from accountability, and dual-class structures can deliver control with little economic exposure. Check *voting* power separately from economic ownership.
- **Float and liquidity** - very high insider ownership leaves fewer shares to trade, which can make the price swing harder in both directions.

## Low ownership is not a problem by itself

A 0.5% CEO stake in a trillion-dollar company is still worth billions of dollars. The trend tells you more than the level. Low ownership plus heavy scheduled selling means management's stake keeps shrinking. Low ownership plus new open-market buying, especially [CEO buying](https://insideralpha.ai/learn/ceo-buying-own-stock) or a [cluster](https://insideralpha.ai/learn/cluster-buying), means insiders are choosing exposure they did not already have. Either pattern is a reason to open the filings.

## How to check it

The company's proxy statement has a beneficial-ownership table covering directors, officers, and 5% holders. Each Form 4 shows the shares the insider reported owning after the trade. On InsiderAlpha, every [company page](https://insideralpha.ai/companies) lists recent insider filings and a 90-day split of insider buying and selling by dollar value, and the [sector pages](https://insideralpha.ai/sectors) group companies by industry.
