Small-cap stocks are often overlooked by investors, but they have the potential to be competitive in the long run. However, it is important to identify the right small cap stocks, since there is a lot of risk involved when trading with small cap stocks.

Although these are strong companies in many cases, the stocks can be more volatile and harder to find analyst research on. We’ll review 10 popular small cap stocks UK and show you how to invest in them.

Small Cap Stocks Stocks 2021

There are thousands of small cap stocks trading on the New York, London, and NASDAQ stock exchanges, which can make finding small cap stocks difficult. We’ve put together a list of 10 available small cap stocks in the UK in 2021.

  • Axos Financial 
  • Waitr Holdings

  • Novavax 
  • Unisys 
  • Vista Outdoor 
  • Shield Therapeutics

 Small Cap Stocks UK Reviewed

1. Axos Financial

Axos is an online-only lender and financial services company that was hit hard by the coronavirus pandemic. Unlike some of its peers in the finance industry, Axos doesn’t have an investment banking industry. So it faced a slower recovery thanks to a drop in interest rates and lending.Axos Financial Chart

The company has a rock-solid loan portfolio, with more than 95% of its loans backed by assets like homes and vehicles. Finally, Axos has an exclusive partnership with H&R Block that gives it access to a huge base of consumers.

The Axos share price has gained over 90% since September. The company is currently trading with a modest PE ratio of 12.8.

2. Waitr Holdings

Waitr Holdings had a breakout 2020. The company’s shares gained a whopping 694% last year, yet it’s still trading at just 20 times forward earnings.Waitr Holdings Chart

Waitr is a food delivery company competing with the likes of DoorDash and Grubhub. But whereas Doordash and others mostly serve city markets, Waitr Holdings operates in rural and exurban areas. That’s a hard logistical nut to crack, but Waitr has managed to solve it while actually turning a profit.

3. Quartix

Quartix is a fleet management company that provides subscription-based software that tracks vehicles and drivers. Before the COVID-19 pandemic struck, the company was adding customers at a rapid pace.Quartix Chart

The company’s PE ratio is currently at 30.8.

4. Smith and Wesson

Smith and Wessonis a US gun maker company with a share price that rises and falls with political winds – shares slowly trended downward during the gun-friendly Trump administration, then shot upwards during the civil unrest last year and spiked again after the election of Joe Biden.Smith and Wesson Chart

Smith and Wesson is currently trading with a PE ratio of 30.2, which is somewhat pricey for a company that’s been around since the 19th century. It also pays out a dividend yield of nearly 1%.

5. Surface Transforms

Surface Transforms is another UK small cap stock worth watching. This company makes ceramic brakes for vehicles, the market for which is estimated to be worth around £200 million per year.Surface Transforms Chart

Right now, that market is dominated by a rival brake manufacturer owned by BMW. Many of BMW’s competitors don’t want to help a rival, so the sector is ripe for disruption. Surface Transforms is on its way to being that disruptor after winning a handful of new supply contracts last year. In fact, the company is expecting to be profitable this year for the first time.

6. Novavax

Novavax was one of the big winners of the coronavirus pandemic. This biotech company began developing its own vaccine candidate at the outset of the pandemic, and investors drove up the stock over 3,200% in response. The company just launched a Phase 3 clinical trial and early results could come out as soon as March.Novovax Chart

At the same time, the company has a new flu vaccine, called NanoFlu, in the works. Both NanoFlu and the COVID-19 vaccine could hit the market next year. The market for both vaccines is global – and despite vaccines from Pfizer and Moderna rolling out, many countries are still in need of millions of vaccine doses.

Novavax isn’t profitable yet, and the shares are trading at an extremely high market capitalization compared to the start of 2020.

7. Unisys

Unisys is one of the most undervalued small cap stocks on the market in our opinion. This company is trading with a PE ratio of just 1.5. That’s comparatively low for a company that provides IT services, an extremely hot and fast-growing market sector.Unisys Chart

Unisys has also sold off a portion of its business for 13 times its earnings last year, just before the COVID-19 pandemic hit. That’s a massive multiple that increases the company’s valuation by a huge degree compared to its share price. Unisys is planning to use the cash to pay down debt and open up growth options.

Unisys’s stock price has more than doubled since October.

8. Vista Outdoor

Vista Outdoor, which owns a number of outdoor recreation and hunting brands, had a strong 2020. The company’s shares grew 300% as outdoor activities were among the only options available to consumers in the US last year. The company saw another bump in November and December thanks to a spike in ammunition sales around the election of Joe Biden.Vista Outdoor Chart

The company has also experienced a recent growth in eCommerce. Gross profit from online sales grew 79% in the fourth quarter, and earnings jumped from $0.01 in Q4 2019 to $1.10 in Q4 2020. Vista has a forward PE of just 10.7.

9. Shield Therapeutics

Shield Therapeutics, which makes a drug for iron deficiency anemia, lost more than 70% of its share value last year as COVID-19 took center stage. However, that poor performance hides the fact that Shield Therapeutics received regulatory approval for its flagship drug and the company has now moved onto commercial distribution.Shield Therapeutics Chart

The next challenge ahead for Shield is moving into global markets. The company already has a deal in place that will allow sales in China as soon as 2023, and it’s actively pursuing distribution in the US.

10. Advanced Medical Solution

Advanced Medical Solutions, a UK small cap stock focused on surgical technology, was hit hard by the COVID-19 pandemic. Elective surgeries came to a near halt, and the stock dropped 12% for the year while the overall stock market was rising.Advanced Medical Solutions Chart

That said, we think this offers an opportunity for UK investors.

What Are Small Cap Stocks UK?

Small cap stocks are any stocks with a market capitalisation between $300 million and $2 billion. By contrast, mid cap stocks have a market cap between $2 billion and $10 billion, and large cap stocks have a market cap of over $10 billion.

You might be surprised at how many small cap stocks are out there. These companies often don’t have the name recognition of their larger peers and they aren’t on the major S&P 500 or FTSE 100 indices since these groups are based on market capitalisation.

However, there are thousands of small caps on the NYSE, NASDAQ, and London Stock Exchange. Collectively, they make up tens of billions of pounds in market value.

How to Analyse Small Cap Stocks

One major thing that keeps many investors from trading small cap stocks is that they can be tricky to review.

Finding small cap stocks worth investing in takes a ton of time. There are thousands of them, and very few receive attention from analysts. Creating a small cap stocks list and then researching all of the companies on it can be a full-time job.

There are several ways to go about finding worthwhile small cap companies. Using a stock screener can help you narrow your search by stock market, industry, and key metrics like recent performance, profitability, and earnings. From there, though, you’ll still need to do the hard work of researching each individual company that appears in your small cap stocks list.

Of course, it’s also important to look carefully at market potential. Does the small cap company you’re researching have competition in its sector, or is it pioneering an entirely new product? What’s the size of the total market opportunity, and how much market share can that company reasonably expect to grab in the next several years.

It is important to conduct your own research and evaluate the stocks before making an investment decision.

Small Cap Stock Brokers UK

Many brokers that have a limited selection of stocks only enable you to purchase shares of larger companies. So, it’s important to look closely at what markets your broker has access to and whether you’ll have a wide selection of small cap shares available.

In addition, it’s important to look at other factors that will affect your trading. For example, commissions and fees can affect your returns in the market. Other factors such as the availability of tools & features can also be factored in when investing in stocks.

Below, we have reviewed some popular UK brokers that allow users to invest in small cap stocks.

1. Fineco Bank

Fineco BankFineco logo is one of the largest banks in Italy and it also has a trading division that’s available to UK traders. Although it’s not the most well-known broker in the UK, Fineco has a lot to offer.

Users may sort through the entire complement of stocks that Fineco offers by market cap, country, market sector, fundamentals, and recent performance. Finceo Bank also lets users use a suite of visualization tools to compare the stocks in your results list to help you find potential small caps to purchase .stock screener at Fineco

How to Invest in Small Cap Stocks in the UK

If you choose to invest in small cap stocks, users should do so with a suitable broker that tends to their needs and requirements.

After selecting a broker, here is how you can begin trading in small cap stocks.

Step 1: Open Account

Head over to the homepage of your trusted broker and begin the account set-up process. You will be required to fill in your personal details – including your full name, email address and mobile number. Create a username and password for the platform to continue.

Step 2: Verifiy Your Identity

Most reputable brokers in the UK are regulated by the FCA – which is why users may be required to verify their accounts. To do this, simply upload proof of ID (a copy of your driver’s license or passport) and proof of address (a copy of a bank statement or utility bill). Once these documents have been uploaded, your broker should verify them in a couple of minutes.

Step 3: Deposit funds

The next step is to deposit funds into your trading account. You may do this by choosing your preferred payment method that the broker supports. These may include:

  • Credit card
  • Debit card
  • Bank transfer
  • e-wallet

Choose your preferred payment option and deposit the funds into your account.

Step 4: Invest in Small Cap Stocks

Once your account has been funded, proceed to search for your preferred small cap stock on your platform’s search bar. Fill in the amount you want to credit into the trade, and confirm your transaction.


Small cap stocks offer high growth potential compared to larger companies, although they also come with more risk. Thus, users should conduct their own individual analysis and research, before deciding to invest in any stocks available.
