What is investing?
Investing is the process of putting money into assets – such as stocks, bonds, property, or businesses – with the goal of generating a financial return over time.
Rather than simply saving money in a bank account, investing aims to grow your wealth by earning income (like interest or dividends) or by benefiting from an increase in the value of the assets you own.
The idea is to make your money work for you, helping you build long-term financial security.
But while investing offers the potential for higher returns than saving, it also carries risk – asset values can go down as well as up, and returns are not guaranteed. Past performance is no guarantee of future returns
An easy way to start investing is opening a stocks and shares ISA.
What are stocks and shares?
Stocks and shares both refer to units of ownership in a company, and the terms are often used interchangeably.
When you buy a share (or stock) in a company, you’re buying a small part of that business.
As a shareholder, you may earn money if the company does well through dividends (a portion of profits) and if the share price increases, allowing you to sell at a profit.
How can I buy and sell shares?
Investors buy and sell shares with the intention of making a profit.
To buy and sell shares, you’ll need to use a stockbroker or online investing platform that gives you access to the stock market.
Shareholders have the ability to trade their shares on the stock market, with share prices fluctuating in response to a company's performance and market projections. It's this volatility that can make investing in shares both exciting and nerve-wracking.
How does investing work?
Investing works by putting your money into assets – like stocks, bonds, or property – with the goal of growing its value over time or earning income. Diversification is spreading the risk by investing in different assets.
When you invest, you’re using your money to buy something that has the potential to increase in worth or generate regular payments, instead of just holding onto cash, which can lose value due to inflation.
The principle behind investing is to buy low and sell high. However, this is easier said than done, as the market is unpredictable and comes with various risks that can impact the value of investments.
You should invest with a long-term, not short-term, view.
How can I invest in the stock market?
Here is how you can begin investing in the stock market:
Pick an account that suits your goals
Pick an account that suits your goals:
Stocks & Shares ISA (UK): Tax-free growth and income
Lifetime ISA (LISA): Ideal for first home or retirement (with 25% bonus)
General Investment Account (GIA): No tax benefits but no limits
Choose a platform or broker
Self-directed platforms: AJ Bell, Hargreaves Lansdown, Freetrade
Robo-advisors: Nutmeg, Wealthify, Moneybox (they manage it for you)
Compare fees, investment choice, and ease of use
Decide how much to invest
You can either invest a lump sum or start with small regular payments - even £25/month is fine.
Pick your investments
Options include:
Shares
Funds
ETFs
Bonds
Understand the risks
Investment values go up and down – you shouldn’t take action in response to every market move.
Invest with a long-term view
Diversifying your portfolio is one way to lower risk.
Regular reviews
Check your portfolio every few months – not daily.
Consider reinvest dividends to boost compounding – alternatively, regular dividend payments can top up your income.
Adjust your portfolio if your goals or circumstances change.
What is capital gains?
Capital gains are the profits you make when you sell an asset for more than you paid for it.
In investing, this usually applies to things like:
Company shares
Property (that’s not your main home) or real estate
Cryptocurrency
Collectibles (like valuable art or antiques)
For example, if you buy shares for £2,000 and sell them later for £3,000, your capital gain is £1,000.
Investments don’t always make a capital gain; some make a loss. Your aim as an investor is to make a capital gain - or profit.
Types of investments
There are various types of investment, known as asset classes, each with its own potential benefits and risks:
Bonds
Bonds act as loans to companies or governments, offering investors a fixed return over a specified period. They are generally considered a more stable investment compared to stocks.
ETFs
Exchange-Traded Funds (ETFs) are investment funds traded on stock exchanges, much like stocks. They track an index, commodity, bonds, or a basket of assets and can offer a diversified investment portfolio.
Stocks and shares
Directly investing into companies by purchasing a unit of ownership.
Alternative investments
Alternative investments are types of assets outside the traditional categories like stocks, bonds, and cash. This category includes things like art, gold, and fine wine.
Finding the right investment for you
Choosing the right investment strategy is a personal decision that should align with your risk tolerance and financial goals.
For the cautious investor
If you're very cautious and don’t want to risk the possibility of losing any money, then consider opening a savings account with a set interest rate instead.
Alternatively, ETFs are generally considered low-risk investments, especially if you’re looking to make a long-term investment with a low level of risk.
Open to risk
Those who are more open to taking risks might find themselves drawn to investing in companies, accepting the potential ups and downs brought on by market volatility.
What is a stocks and shares ISA?
A stocks and shares ISA is a UK tax-free investment account that lets you invest in a wide range of assets – like stocks, funds, and bonds – while protecting your profits and income from tax.
You can save or invest up to £20,000 in an ISA each tax year.
Starting with small investments
The good news for beginners is that you don’t need a large sum to start investing. Some platforms allow you to start with as little as £1, making it accessible for everyone.
Potential losses
Investment losses occur when the value of your investment drops below what you paid for it. This means you could get back less than you originally invested, especially if you sell during a downturn or if the company you invest in performs badly.
Investment costs
There are various fees can eat into your investment returns:
Transaction fee
When buying or selling shares, there may be transactions fees for buying and selling, which can vary depending on the platform or broker you use.
Management fee
For those who invest through a fund manager or require an investment manager, there will be a fee for the management of those funds.
Advice fee
If you decide to seek financial advice, you will need to pay the adviser a fee.
Platform fee
Using an investment platform usually comes with a fee for maintaining your investments on their system.
What should I consider before I start investing?
Before you start investing, there are several factors to consider:
Have an emergency fund: Ensure you have 3-6 months of living expenses saved before you begin investing
Think long term: Investments should generally be considered for a minimum of 5 years
You could lose money: Always be aware that there's a risk of losing your investment - how much this will affect you depends on your financial situation
Market volatility: Be prepared for the ups and downs in the value of your investment
Tax-efficiency: Use ISAs to shield your investments from income tax and capital gains tax.
