<p>In the realm of finance, a share, also known as a <a href="/NewSite/encyclopedia/stock/" class="ency-link">stock</a>, represents a unit of ownership in a company. When a company issues shares, it's essentially selling a piece of itself to investors. These investors then become shareholders, owning a fraction of the company and having the right to participate in its profits and decision-making processes.</p>

<h2>How It Works</h2>
<p>Shares can be issued in various forms, including common and preferred stocks. Common stocks are the most prevalent, offering voting rights and a claim to a portion of the company's profits. Preferred stocks, on the other hand, may not carry voting rights but offer a higher claim to the company's assets and earnings. When you buy a share, you're purchasing a small piece of the company's capital, and your share price will fluctuate based on the company's performance and market conditions.</p>

<h2>Why It Matters</h2>
<p>Shares matter because they are a fundamental component of the stock market and a key tool for investors to participate in the growth and profits of companies. By owning shares, investors can benefit from capital appreciation (an increase in the share price) and receive dividends (a portion of the company's profits distributed to shareholders). Moreover, shareholders have a say in the company's affairs through voting rights, which can influence the company's direction and strategy. Understanding shares is crucial for anyone interested in investing in the stock market and building long-term wealth.</p>
