Understanding Stocks Before You Invest.
Learn how shares work, what drives stock prices, how investors can approach risk and diversification, and what to consider before buying individual companies.
What Are Stocks?
A stock, also called a share or equity, represents an ownership interest in a company. When you buy shares in a publicly traded business, you become a shareholder and your investment can rise or fall depending on the value of those shares.
Companies issue shares to raise capital. Investors may buy those shares because they believe the business can grow, generate profits or provide income through dividends. However, there is no guaranteed return and the value of an investment can fall.
Unlike a cash savings account, shares are exposed to market movements. The price can change because of company results, economic conditions, interest rates, investor expectations, industry developments and wider market sentiment.
For this reason, understanding what you are buying and how much risk you can afford to take is an important part of investing in individual stocks.
How Does Investing in Stocks Work?
Investing in stocks usually involves opening an investment account or using an investment platform, adding money and choosing shares you want to buy. The shares are then held within the account, and their value changes as the market price changes.
There are two broad ways shareholders can potentially benefit. The first is capital growth: if a company's share price increases and you eventually sell your shares for more than you paid, you may make a gain. The second is income from dividends when a company chooses to distribute profits to shareholders.
Neither outcome is guaranteed. A company can perform poorly, market expectations can change, or broader economic conditions can cause its share price to fall. You could therefore lose some or all of the money invested in an individual stock.
Why Do Share Prices Move?
Share prices reflect what buyers and sellers are willing to pay. That can be influenced by the company's financial performance, expectations about future earnings, management decisions, competitive conditions and the wider economy.
For example, a company reporting stronger-than-expected earnings may attract more buyers. Conversely, disappointing results, weaker forecasts or a deterioration in its industry may reduce demand for its shares.
Interest rates, inflation, currency movements, political developments and global economic conditions can also influence markets. This is one reason why a good company can still experience periods of falling share prices.
Stocks vs Funds
Buying an individual stock gives you direct exposure to one company. A fund can instead hold a collection of investments, spreading your exposure across multiple companies or assets.
This distinction matters because holding only a few individual companies can create concentration risk. If one company performs badly, a large part of your portfolio may be affected.
Diversification can reduce reliance on any single investment. The FCA explains that spreading investments across companies, sectors and markets can help dilute the impact of one investment performing badly, although diversification cannot eliminate investment risk.
How Long Should You Hold Stocks?
Stocks are generally more appropriate for investors who can tolerate market fluctuations and have a sufficiently long investment horizon. Short-term prices can be unpredictable, while a longer horizon gives an investor more time to experience different market conditions.
MoneyHelper notes that if a savings goal is more than five years away, investing may be worth considering, while also stressing that investments can fall in value.
A long-term approach does not mean ignoring your investments. It means avoiding the assumption that every short-term market movement requires a reaction.
What Should You Research Before Buying a Stock?
Researching a company involves more than looking at its recent share price. Investors may consider the company's business model, revenue, profits, debt, competitive position, industry conditions and future prospects.
- What does the company actually sell?
- How does it make money?
- Is revenue growing or declining?
- How profitable is the business?
- Does it carry significant debt?
- What competitive advantages does it have?
- How sensitive is the company to economic conditions?
- Is the current valuation reasonable relative to the business?
- What risks could change the investment case?
Stocks and Dividends
Some companies pay dividends to shareholders. A dividend is a distribution from a company to its shareholders, usually based on the company's profits and dividend policy.
However, investors should not assume that a dividend will continue indefinitely. Companies can reduce, suspend or stop dividends depending on their financial position and priorities.
A high dividend yield should therefore not automatically be treated as a sign of a better investment. It is important to understand why the yield is high and whether the underlying business can support the payments.
Stocks and Investment Risk
The possibility of higher returns comes with investment risk. The FCA highlights the relationship between risk and potential return and recommends considering whether you can afford to lose money before investing.
Individual stocks can be particularly exposed to company-specific risk. An unexpected regulatory change, product failure, management problem, legal dispute or competitive threat can affect one company much more severely than the wider market.
This is why diversification, a suitable time horizon and an investment amount that fits your wider financial circumstances matter.
Important Factors When Researching a Company
There is no single metric that tells you whether a stock is a good investment. Looking at several aspects of a business can provide a more complete picture.
Revenue & Profit
Look at whether the company's sales and profits are growing, stable or declining and understand what is driving those changes.
Research earnings →Debt & Cash
A company's debt position can affect financial resilience, particularly when borrowing costs rise or business conditions weaken.
Understand finances →Business Model
Understand what the company sells, who its customers are and how it generates revenue before considering the shares.
Understand the business →Valuation
Consider whether the current share price appears reasonable relative to the company's earnings, growth expectations and financial position.
Explore valuation →Growth Prospects
Think about the company's market, competition, products and ability to grow revenue and profits over time.
Think long term →Risks
Identify the events or conditions that could damage the investment case before deciding how much risk you are prepared to accept.
Assess risk →How to Approach Your First Stock Investment
There is no guaranteed formula for choosing successful shares. A structured process can, however, help you avoid impulsive decisions.
Get Your Finances Ready
Deal with urgent short-term debt, maintain an appropriate emergency fund and understand how much money you can realistically invest.
Define Your Goal
Think about why you are investing, how long the money can remain invested and how much volatility you can tolerate.
Research the Company
Understand the business, financial results, competitive position, valuation and risks instead of relying only on market hype.
Review Your Portfolio
Consider whether the investment leaves you overly dependent on one company, sector, country or type of asset.
Higher Potential Returns Always Come With Investment Risk
Stocks can provide long-term growth and, in some cases, dividend income. But the value of shares can fall, sometimes sharply.
The FCA recommends understanding the balance between risk and return, considering whether you can afford losses and spreading investments to reduce dependence on any single investment.
Stocks & Shares ISA
Stocks Can Also Be Held Inside an ISA
A Stocks & Shares ISA is an investment wrapper that can be used to hold qualifying investments. Investments held within an ISA can benefit from the tax treatment available under the ISA rules.
An ISA does not remove investment risk. The value of investments can still rise and fall. The benefit comes from the tax treatment that can apply to qualifying investments held within the wrapper.
