What are shares and why do they matter?
A share represents ownership in a listed company. When you buy shares directly, you become a partial owner of the company in proportion to the number of shares you hold. This may give you the right to receive dividends and to vote on certain company decisions, depending on the share type and company policy. Shares are a fundamental part of financial markets: companies use them to raise capital and fund expansion plans, while investors and traders are attracted by their diversity, liquidity and the potential to benefit from short-term price changes or long-term value growth.
How to participate in the stock market
There are two main ways to access the stock market. The first is direct share purchase, where an investor buys the share on an exchange and becomes its actual owner, often holding it for a long time to benefit from value growth or potential dividends. The second is stock CFD trading, which lets you speculate on share price movements without actually owning the shares. You can open a buy position if you expect the price to rise, or a sell position if you expect it to fall. With CFDs you do not receive company ownership or voting rights; the trade result depends on the difference between the opening and closing price after spreads, fees and applicable costs.
Shares that attract traders
Some company shares attract wide interest because of their size, market influence and the volume of news around them. Well-known technology companies include Apple, Amazon, Microsoft, Meta and Tesla. Companies from other sectors, such as Disney in entertainment and Walmart in retail, are also closely followed because of their broad operations and the way their share prices react to news, financial results and economic changes. A company's popularity does not mean its share suits every trader, since volatility, liquidity and risk vary from one share to another.
Example of trading stock CFDs
Suppose Apple is trading at USD 120 and you expect the price to rise after a new product announcement, so you decide to open a buy CFD trade instead of buying the share directly. If the trade size equals 1,000 shares, your total market exposure would be USD 120,000. Using 20:1 leverage, if available under your account terms, the margin required to open the trade could be USD 6,000. If the price rises from 120 to 130, the price difference is USD 10 per share, or USD 10,000 on the trade size before fees and costs. If the price falls to 110, the trade could result in a loss of USD 10,000 before costs. This example is educational and simplified: leverage reduces the amount needed to open a trade but does not reduce market exposure, so it can magnify both profits and losses.
How shares affect market indices
Stock indices are made up of selected groups of company shares and are used to measure the performance of a market or sector. Major global indices include the S&P 500, Nasdaq 100 and Dow Jones. Each index's movement is affected by the performance of its constituent shares, although the impact of each company depends on how its weight is calculated. Market-cap-weighted indices give larger companies more influence, so price moves in big companies can clearly affect overall index performance. Price-weighted indices give higher-priced shares more influence regardless of total market capitalisation. A strong move in a single heavily weighted share can therefore shift the direction of the index.
Why trade stock CFDs?
Stock CFDs offer flexibility in different market conditions. Key features include the ability to trade rising or falling prices, access to global company shares from one platform, the possibility of using leverage according to trading terms, fast reaction to earnings reports and economic news, and diversified trading opportunities across companies, sectors and markets. These features do not guarantee profits, and using leverage significantly increases risk.
Factors that move share prices
Share prices can change due to a wide range of factors, including company results and earnings reports, revenue and growth levels, new product or service launches, management decisions and executive changes, competition within the sector, interest rates and inflation, economic and political conditions, and investor expectations and market sentiment. Trading shares therefore requires following company data, understanding the sector in which the company operates, and monitoring broader economic developments.
Risks of stock trading
Share prices can be highly volatile, especially around earnings releases or unexpected news. A fast price move can lead to significant losses if a trade is not managed properly. Risk increases when using leverage because it allows you to open positions larger than the margin capital used. Therefore, it is essential to choose position sizes carefully, use risk management tools and never trade with money you cannot afford to lose.
