🏦 Comparison of stock brokers in 2026

Here is the simplest way to explain what the stock market is: imagine a huge marketplace where the stalls sell shares in companies, known as “stocks” or “shares”. By buying a share, you become the owner of a very small part of that company.

When lots of people want to buy a company’s shares, a bit like a crowd gathering around a busy stall, demand rises and the share price generally tends to go up.
Conversely, when more investors want to sell their shares and there are fewer buyers around, the share price generally tends to fall.

Why do investors buy or sell? Of course, they look at the company’s current situation, but above all they focus on what they expect to happen next. Strong results, a new project, favourable economic conditions or simply better prospects can attract more buyers. On the other hand, bad news or less encouraging outlooks may lead some investors to sell.

So, above all, a share price moves according to what buyers are willing to pay and sellers are willing to accept, together with their expectations about the company’s future.

Let’s go back to our marketplace example. By buying a share, you become the owner of a very small part of the company. If the company makes a profit, it may decide to distribute part of it to its shareholders.

The amount you receive is called a dividend. However, this payment is not automatic: even when a company makes money, it may prefer to keep its profits to invest, expand or strengthen its cash position. Some companies therefore pay dividends regularly, while others do not pay any at all.

Investing, especially in the stock market, always involves a degree of risk. However, a long-term view can help put those ups and downs into perspective.

Let’s take a practical example:

You have just bought shares in a company. Naturally, their price will fluctuate over time: on some days it will rise, on others it will fall, particularly depending on the company’s results, the economy and investor expectations.
Let’s imagine the price of your shares falls after you buy them. If you panic and decide to sell straight away, you then lock in your loss: you have sold your shares for less than you paid for them.
If, on the other hand, you decide to keep your shares, their value has certainly fallen, but that decline remains an unrealised loss until you sell. The price may continue to fluctuate and, if the company performs well over time, it may also recover.

That is the whole point of a long-term approach: not drawing conclusions about your investment every time the market moves. A share can go through periods of decline and then start rising again. Of course, a recovery is never guaranteed, which is also why it is generally better to diversify your investments rather than rely on a single company.

To invest in the stock market, you will mainly come across three major wrappers: the General Investment Account, the Stocks and Shares ISA, and investment bonds. ETFs are slightly different: they are not accounts, but funds that you can buy within some of these wrappers.

• The standard General Investment Account (GIA): this is the most flexible option. There is no contribution limit and you can access a very wide selection of shares, ETFs and international markets. Your money is not locked away, and you can sell your holdings and withdraw your funds whenever you like. You can open a General Investment Account with an online broker or with a bank.
• The Stocks and Shares ISA: think of it as a tax-friendly home for your investments. You can hold eligible shares, funds and ETFs inside it, and dividends and capital gains made within the ISA are generally free from UK income tax and capital gains tax. In 2026/27, you can put up to £20,000 per tax year across your ISAs. That makes it a particularly useful option if you are investing for the long term and want to keep things simple from a tax point of view.
• ETFs: an ETF is a listed fund that seeks to track an index such as the FTSE 100, the S&P 500 or the MSCI World. Its main advantage is diversification: with a single purchase, you can invest indirectly in dozens or even hundreds of companies. ETFs often come with low management fees and can be bought through a General Investment Account, certain Stocks and Shares ISAs and, depending on the policy, investment bonds.
• Investment bonds: these are long-term investment products, usually offered by insurance companies, that invest your money in one or more funds. They follow their own tax rules and can be useful for certain long-term saving, income or estate-planning needs. As the charges, access rules and tax treatment vary, it is worth checking how a particular bond works before deciding whether it fits your plans.
