There is a thing that happens to almost everyone at some point in their mid-twenties. You read something about stocks, or your friend mentions their ISA. Maybe you watch fifteen minutes of a finance video before it becomes too much and you close the tab. You think “I should probably be doing something with my money”. And then you don't.

The reason is almost never laziness. It's that "stocks for beginners" content tends to assume one of two things. Either that you have several thousand pounds sitting around doing nothing while you wait to use it, or that you are prepared to become the kind of person who tracks individual company performance across multiple markets before your morning coffee. Most people are neither. Most people have a bit left at the end of the month, if that, and would like it to grow somewhere while they get on with their lives.

The good news is that having a little bit is all you need to get started.

First, let's talk about what "buying a stock" really means

A stock is a small piece of a company. You give them some money, you own a slice, and if the company does well, your slice is worth more. If it doesn't, it's worth less. That is the whole thing. There are books, courses and entire YouTube channels dedicated to expanding on this, and they are largely unnecessary for most people.

Where most people go wrong early is assuming that "investing" means picking a company, choosing whether to back, say, a tech giant or a retailer or whoever is in the news. Then hoping they've called it right. This is not investing. This is a guess. And for someone starting out with a small amount of money, it's a particularly bad guess, because you've put everything into one answer.

The alternative to guessing is more interesting.

The case for not trying to pick the winners

Index funds don’t require you to guess anything. Instead of buying a piece of one company, you buy a piece of a very large basket of companies – sometimes hundreds, sometimes thousands – spread across different sectors and countries. If one goes badly, the others absorb it. If most go reasonably well, you do reasonably well.

This is how the majority of professional fund managers invest their own money, by the way. Not in high-stakes individual stock picks. In index funds. Because even people whose entire job is analysing this stuff can’t reliably outperform the market over time. The least exciting option turns out to be the most sensible one.

For a beginner with, say, £25 or £50 a month, an index fund is usually the correct answer.

What should a beginner invest in?

There are a few different flavours worth knowing about.

Global equity index fund

Probably the most sensible starting point for most people. A global equity fund tracks a big spread of companies from across the world with a heavy reliance on the US, because American companies make up a large chunk of the global market, but with meaningful exposure elsewhere too. You're not betting on any single country's economy doing well. Instead, you’re betting on enough of the world not collapsing at once, which, historically, has been a reasonable bet. 

UK index fund

A UK index fund does the same thing but is narrowed to British companies. Lower fees sometimes, more familiar names, but less diversified. Not necessarily wrong; just more concentrated.

Money market fund

A money market fund is the cautious end of the scale. It’s not really "stocks" in the traditional sense. It’s more like a holding place that earns a bit more than a standard savings account, with minimal risk. Helpful if you're not ready for the ups and downs of equity investing but want to do something more than leave money in cash.

The honest answer to "which one?" is probably a global equity index fund, maybe inside a Stocks and Shares ISA so your returns aren't taxed on up to £20,000 contributed per year, and ideally set up on a regular contribution so you don't have to think about it. This is not a thrilling recommendation. It is, however, the one most financial advisers would probably give you.

How much do you actually need?

Less than you think. The entry barrier for index fund investing has fallen dramatically, with plenty of platforms now letting you start from £1, though somewhere between £20 and £50 a month is a more helpful starting point in terms of building up anything meaningful over time.

The number is less important than the consistency. £50 a month invested for 20 years at a fairly modest average annual return compounds into something genuinely significant. £50 a month sitting in a current account compounds into exactly nothing, because current accounts are not paying you for the privilege.

Time does the work here more than the amount. Getting started at 25 with very little beats starting at 35 with more, in almost every realistic scenario.

A note on risk, because you deserve the honest version

Stocks go down. Sometimes for a few months, sometimes for a few years. If you invest £500 and the market drops 20%, you will briefly have £400. This is uncomfortable. It is also temporary, in every sustained period of history we have on record, though past performance is not a guarantee of future results, and all the appropriate caveats apply.

The mistake most people make when the market goes tumbling is selling. The people who lose money in index funds are almost always the ones who panic and sell low, trying to time their way back in. The people who don't look at it for a decade and let it compound are usually the ones who end up with something worth having.

None of this means you should invest money you can't afford to not have access to. Emergency funds, rent – anything you might need in the next two or three years should stay liquid, in savings, not in the market. Investing is for money you can genuinely put somewhere and leave.

Where Kaldi fits in

That would be us. We’re an investing app built for exactly this kind of person, someone who's new to it and doesn't have a huge amount to start with. Ideally, you’d like the whole thing to be considerably less faff than it currently feels.

The way it works is that you earn cashback when you shop with brands on the platform – Amazon, Asda, Boots, Deliveroo and over a hundred others – and you can set that cashback to automatically put into your chosen investment fund. Your weekly shop, your holiday flights, weekends away: they're adding to your pot in the background without you having to do anything extra.

In terms of what you can invest in, we offer a range of funds including Vanguard LifeStrategy funds at different risk levels, which are exactly the kind of diversified global index fund described above. Risk levels are clearly labelled, so you're not guessing what you're getting into.

You can start from £1, and can set up auto-invest so the whole thing just runs. The cashback and roundups from your spending mean that even if you're not putting in much extra, your pot grows from money you were essentially already spending.

You can also link up to five friends or family members' accounts so their cashback feeds into your goal too.

The best stocks around

Stocks for beginners doesn't need to mean anything complicated. It means finding a diversified fund and setting up a recurring contribution you can afford. Then leave it alone. The getting started part is harder than the actual investing part. Once it's running, there's almost nothing to do.

The question is less "what stock should I pick?" and more "am I ready to just start?" The answer, for most people reading this, is yes.

Capital at risk. The value of your investments can go up or down, and you may get back less than you put in. Tax treatment depends on personal circumstances and is subject to change in the future. Kaldi provides tools and information to help you invest but does not offer personal financial advice. If you're unsure, consider speaking to a qualified financial adviser.
