What are the basics of share? — A plain-language guide

What a share is and why it matters

Definition in plain language (basic of shares)

A share is a unit of ownership in a company that gives the holder a claim on the companys economic results, and sometimes a role in governance through voting rights.

This ownership claim differs from a creditor claim because shareholders share in residual profits and losses, while creditors hold a right to repayment; this basic distinction is central to investor education and regulatory guides SEC investor guide.

Companies issue shares to raise money for growth, to let founders and early investors transfer ownership, or to meet strategic goals such as aligning incentives; exchanges and regulators present issuing equity as a common corporate financing route FCA guide to buying shares.

For new readers, keep terms simple: the company that issues shares is the issuer, people who hold shares are shareholders, and equity means ownership rather than debt.

How companies issue shares: the primary market

When a company needs external capital it can issue new shares directly in the primary market, which is the formal route companies use to sell ownership to investors.

One common method is an initial public offering, or IPO, where shares are sold to the public and a prospectus explains the offer terms; private placements are an alternative where shares are sold directly to selected investors instead of the broad public FCA guide to buying shares. For a clear primer see primary vs secondary markets.

Typical parties in an offering include the issuer, underwriters who help arrange the sale, and legal advisers who prepare filings; companies may choose equity rather than debt for reasons like avoiding fixed interest payments or sharing risk with investors Nasdaq overview of market roles.

Before an offering, companies prepare a prospectus or offering document that lists risks, fees, and ownership terms; reading that prospectus is the primary way to verify exactly what rights a new share grants.

Types of shares: common, preferred and share classes

Most public companies issue at least two broad types of equity: common (ordinary) shares and preferred shares, which differ in voting and payout priority.

Common shares generally give voting rights and a residual claim on assets after creditors and preferred shareholders are paid, a point emphasized in investor education materials SEC investor guide.

Preferred shares typically offer priority on dividends and on payments if the company is liquidated but often have limited voting rights; market primers explain this tradeoff between income priority and governance influence Investopedia primer on preferred versus common stock.

Companies can also create multiple share classes with different voting weights or economic rights; the exact rights depend on the companys articles and the terms shown in filings, so it is important to check the prospectus or company reports for the precise class definitions SEC investor guide.

Understanding which class you hold matters for decisions like voting on corporate actions or evaluating dividend priority; small wording differences in filings can change outcomes for shareholders.

How shares are traded on secondary markets

After issuance, shares usually trade between investors on secondary markets like exchanges, where brokers route orders and the market price is set by supply and demand.

Exchanges, brokers, and clearinghouses each have roles: exchanges match buyers and sellers, brokers place orders for clients, and clearinghouses manage the post-trade steps that deliver final ownership and reduce settlement risk Nasdaq explanation of trading roles.

Order types matter: a market order executes at the available price, while a limit order sets a maximum or minimum price for execution; the bid-ask spread is the difference between what buyers offer and sellers ask, and it affects execution cost and liquidity Nasdaq guide to order types.

Clearing and settlement are the final steps that move shares and cash between parties, and they ensure the buyer legally becomes the owner; major exchange summaries describe why these processes matter for reliability and final ownership World Federation of Exchanges market structure summary.

Key risks investors should understand

Owning shares carries several common risks, including market volatility where prices fluctuate, company-specific operational risks, dilution risk if the company issues more shares, and liquidity risk if it is hard to buy or sell at a fair price; regulators highlight these as core investor concerns SEC investor guide.

Market volatility means prices can move up or down quickly and past performance is not a reliable predictor of future results, so many education pages stress understanding how volatility fits your time horizon and risk tolerance FCA guide to buying shares.

Dilution happens when a company issues additional shares, which reduces each existing shareholders percentage ownership unless they acquire more shares; prospectuses and company filings disclose plans for possible new issues and are the primary source to check SEC investor guide.

How dilution and corporate actions affect shareholders

Dilution reduces an existing shareholders percentage ownership when new shares are issued; regulators and corporate primers explain that the economic effect depends on what the new capital is used for and the change in share count SEC investor guide.

Common corporate actions include stock splits, buybacks, and rights issues; a split changes the number of shares without changing the companys overall value in simple terms, while buybacks reduce share count and can increase each remaining shareholders percentage ownership under some conditions FCA guide to buying shares.
