Investing for Beginners: The 10 Things You Need to Know

1. What is an Investment?

An investment – or investing – is a long way from putting your cash in a bank account where it sits to earn interest. An investment is a gamble: instead of the security of guaranteed returns, you’re taking a risk with your money. The hope is that you make a lot more than you put in (a juicy profit), but there’s the possibility you end up with less (a nasty loss).

You can invest in almost anything, from the most mainstream popular targets…

  • Shares
  • Bonds
  • Funds
  • Government bonds (gilts)
  • UK property market


…to the rather more exotic, such as…

  • Farmland
  • Vintage cars
  • Wine
  • Fledgling technology firms
  • Art, eg, paintings, sculptures

For most, investing means putting money in the stock market

This guide is first and foremost about investing in stock markets – it’s most people’s first experience of investing. And putting your cash into these markets is exactly what it says on the tin: you buy shares in one or more companies with the aim of making a profit.

And although there are different ways to do it, such as funds (see below), the principle of investing remains the same: you’re taking a gamble with your money as there’s no guarantee you’ll get it all back. In the worst case scenario, you could lose it all.

This message is so crucial, it’s worth repeating:

Investing in stock markets is a gamble: while you could win small or win big, you could lose small or lose big – and end up empty-handed.

While the concept of stock markets may trigger images of young brokers yelling “Buy! Sell!”, heads in hands one minute and fist-pumping the next, the reality of long-term investing tends to be rather more mundane – pick a few shares or funds, keep an eye on them and then cash them in when you need to.

This is not the racy, glamorous or high-adrenaline action you see in Hollywood films where fortunes are made and lost in minutes – and thank goodness.

For the vast majority, it’s about nurturing a reasonable and calm attitude to the stock market in a bid to generate decent investment returns that can weather downturns and ride out wild surges.

2. How do stock markets work?

To keep it as simple as possible, and for the purposes of this guide, a stock market is simply a place where buyers and sellers meet to sell shares – each one a tiny part of a company listed on an exchange (see below).

Why do shares exist in the first place? To grow, and hopefully boost profits to turn a business into a financial success, firms offer investors the chance to back them with their own cash.

Enter a stock market: in return for your cash, a business offers you a share in its future – so you essentially own a tiny slice of that company and become a ‘shareholder’.

And if you wish, this slice of the company you own can then be traded with anyone who wants to buy it.

Why does a company share price rise and fall?

The price is initially set by the firm offering shares but its price on any given day can be determined by poor financial results, the UK’s economic health and so-called ‘sentiment’, ie, if City buyers think a firm will struggle, its price can fall. Or if a company doubles its growth in a year and prospects look rosy, then its price will likely rise.

Here in the UK, on a daily basis, people buy and sell billions of pounds’ worth of shares on the London Stock Exchange. You can trade in any number of roughly 3,100 different types of companies. Shares are listed on an ‘index’ and the UK’s biggest is the FTSE 100 – the 100 biggest firms.

How does a company get listed on the stock exchange?

In industry jargon, ‘going public’ – or becoming a listed company on a public stock exchange where anyone can buy your shares – means striking a deal.

In return for access to investors’ cash (called ‘capital’) used to plough into staff, development and expansion, a firm takes on new responsibilities to investors, employees and the market itself.

To actually be listed, a firm must hire an adviser – usually an investment bank – to draw up a so-called ‘admission document’. This sets out why the firm wants to list, its targets for expansion, and a long-term strategy. Once a level of interest from backers is set, an initial share price is agreed, and trading can begin.

3. What kind of growth can I expect from investing?

This is usually the question that most investors want an answer to – and the very reason behind most people’s decision to put their cash into the stock market. We’ll be blunt: we can’t actually tell you what you will get (and don’t believe anyone who says they know – they’re lying). But we can give you an idea of what can be achieved.

With savings rates hovering at historically low levels – eg, 1.3% on a typical competitive savings account – the incentive to look elsewhere for decent returns is strong.

Of course, everyone would prefer to make 5% on their cash but only if you take the right level of risk to suit you. We’ve said it above but there’s no harm in repeating this till we’re blue in the face…

Warning: Investing is risky and any money you put in could fall in value. Put bluntly, you could lose it all. There’s a reason you’ll see the phrase ‘Past performance is no indicator of future success’ – you’ve no guarantee your investment is going to do well.

To show what’s typical, let’s take the performance of funds. Our table below (with January 2020 figures from the fund analyst Morningstar) shows how average funds in industry sectors and different parts of the world have performed, in terms of monetary growth in GBP (rounded to the nearest pound), over the different periods shown:

SECTOR INVESTING IN… Over one year Over two years Over 10 years
UK Equity Income £20 £20 £127
Corportate Bond £10 £13 £72
North America £25 £36 £251
China/Greater China £22 £43 £111
European countries (but not the UK) £20 £24 £117
Asia (incl Japan) £17 £32 £128
A mix of global stock markets £22 £31 £150

Within each of the sectors above, there are hundreds of funds to pick and choose from. In total, there are well over 3,000 on offer.

In which case, it’s the perfect time to remind about the golden rules…

ALWAYS remember the five golden rules of investing:

  1. The greater return you want, the more risk you’ll usually have to accept.
  2. Don’t put all your eggs in one basket. Try to diversify as much as you can to lower your risk exposure, ie, invest in different companies, industries and regions.
  3. If you’re saving over the short term, it’s wise not to take too much of a risk. It’s recommended you invest for at least five years. If you can’t, it’s often best to steer clear of investing and leave your money in a savings account.
  4. Review your portfolio. A share might be a dud or you might not be willing to take as many risks as you did before. If you don’t review your portfolio regularly, you could end up with a share account which loses money.
  5. Don’t panic. Investments can go down as well as up. Don’t be tempted to sell or buy shares just because everyone else is.

4. Is investing right for me?

It doesn’t matter if you’re about to buy your first share or pick a stock market fund for the first time, always ask yourself WHY you’re looking to invest.

Over the long run, historically stocks and shares have outperformed money in savings accounts.

But that’s no guarantee they’ll do so in future. It’s all about your personal circumstances. For example, you might be one of the many who have despaired at the rotten rates on offer in savings accounts and are prepared to take a risk in the hunt for bigger returns.

Or you may have drawn up a well-researched plan to save £10,000 over the next decade to help pay for your children’s school fees. In both these cases, it’s a clear green light to go and invest.

Be careful if somebody offers you advice

If a friend has suggested a share tip in the pub, or a family member or friend has suggested you “bung a few quid” into a hot share or fund that is currently – in industry jargon – “shooting the lights out”, it’s probably best to think twice unless you’ve money to spare that you can afford to lose.

Take a good, honest look at your finances

If you’re struggling to keep up with credit card payments, say, or have taken on an expensive remortgage and have little savings, it’s time to step back and think again.

This might sound like basic housekeeping, but the lure of quick gains in the stock market can prevent many people from seeing how dire their overall financial situation might be.

If this is you, far better to try to sort out your personal debts than turn the risk of making them far worse: see our Debt Help guides. Or if on reflection a savings account would be a far better home for your money, see our guides to putting money away in a cash ISA or top savings account.

5. How much should I invest?

Too many people think you need to have a load of cash to be able to invest in the stock market – you don’t, and many smaller investors who ‘drip-feed’ in small sums on a regular basis can do much better than those who simply dump a big lump sum into the market.

As a rule of thumb, you should never invest more than you can afford to lose. This is because, in the event of a stock market crash, you could face losing a huge chunk of your wealth if you have too much of your money invested. Many financial advisers would suggest you invest for at least five years. This allows enough time to ride out any bumps in the market that might see you make a loss on your money.

Remember, as we say above, if you’ve little savings and are heavily indebted, gambling on stock markets could be bad for your financial health. If you’ve built up a nest-egg, though, and are fed up with low savings rates, putting a chunk of it (that you don’t need to rely on for living expenses) on the stock market could be a decent way to try to earn bigger returns.

Many fund managers allow you to invest a regular small monthly sum – typically £25 a month (though a few including M&G will go as low as £10 – which will help build up a larger sum over time, as well as being more manageable for your finances).

6. How do I invest?

You can buy shares or funds from different providers, but for the cheapest offers you’ll want to do it through a website, often called a platform.

It’s actually a two-stage process. First you need to pick which platform to buy your shares or funds from, then you need to decide what investments to buy.

It’s like buying bread in a supermarket. You first need to pick where you want to buy the bread (decide which platform to use), then choose which bread you want to buy (your shares or funds).

As a rule, you’ll be charged for using the platform and buying the investment. To stretch the analogy somewhat, imagine each supermarket charges a different price for its shopping bags.

Some supermarket bags are cheaper than others, but the ones that have the most expensive bags may sell the cheapest bread. So it’s a combination of the two factors that needs to be taken into consideration.

Note that while the platform fee is charged by the platform you choose, the company buying the shares on your behalf or running the funds will be charging you for its service.

7. What is a share?

A share is simply a divided-up unit of the value of a company. For example, if a company is worth £100 million, and there are 50 million shares, each share is worth £2 (usually listed as 200p). Those shares can, and do, go up and down in value for various reasons.

Companies issue shares to raise money and investors (that’s you) buy shares in businesses because they believe the company will do well and they want to ‘share’ in its success. See our Shares guide for a full rundown, and remember what you choose will be down to your attitude to risk.

Shares can pay dividends too

8. What is a fund?

A fund is simply another way to buy shares – but instead of you buying a slice of a company directly, you give your cash to a specialist manager who pools it with money from other investors (like you) to go and buy a job lot of shares in a stock market.

Each fund is made up of ‘units’ so if you want to invest, you’ll need to buy units – and these come at a cost which varies from day to day.

The value of each unit will rise or fall (or stay the same, of course) depending on demand in the market for the fund. Say you want to invest £1,000 in a fund; if each fund unit costs £2, you can buy 500 units. Six months later, if each unit is now worth £2.50, your investment is worth £1,250.

Funds can invest in almost anything – countries, energy, gold, oil, even debt

All funds have a theme – anything from geography (European, Japanese, emerging markets), industry (green companies, utility firms, industrial businesses), types of investment (shares, corporate bonds, gilts), to the size of the company. What you choose will be down to your attitude to risk.

Say the fund focuses on ‘fledgling biotech companies in emerging markets’, all the elements involve a high degree of uncertainty. So if it goes well you could be in for massive gains, but if it goes badly, massive losses.

Alternatively, it could be a FTSE 100 tracker, where the fund simply invests in the UK’s 100 biggest companies, and therefore is much more mainstream.

Here, while there can still be substantial ups and downs, the fluctuations are likely to be smaller. See our Funds guide for a full explanation.

9. Investing in an ISA should ALWAYS be your first port of call

Everyone in the UK over 18 has a £20,000 annual ISA allowance – which means you don’t have to pay any tax on any stock market gains you may make.

You can choose to use all of this ISA allowance for a stocks & shares ISA, or you can put some in a cash ISA and the rest in a stocks & shares ISA. New ISA rules that came into effect in 2014 mean you can now split the money between stocks & shares ISAs and cash ISAs any way you like.
