Best Small Cap Stocks UK – Invest with 0% Commission

Small-cap stocks are often overlooked by investors, but they offer potentially larger gains than well-known companies. Small caps have enormous growth prospects since they typically haven’t saturated their markets.

Of course, small cap stocks also come with a fair amount of risk. Although these are strong companies in many cases, the stocks can be more volatile and harder to find analyst research on. We’ll highlight the 10 best small cap stocks to buy in 2021 and show you how to invest today.

Top 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 the 10 best small cap stocks you can buy in 2021 – let’s take a closer look:

Best Small Cap Stocks UK Reviewed

1. Axos Financial – Online Lending Discounted by Pandemic

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

However, Axos is still a strong long term investment. The company has a rock-solid loan portfolio, with more than 95% of its loans backed by assets like homes and vehicles. In addition, Axos’s online-only model makes it much more profitable than competing banks, so it wins even when it undercuts competitors’ interest rates. 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 a lot of momentum right now and has gained over 90% since September. The company is still trading with a modest PE ratio of 12.8, though, so you don’t have to worry about overpaying.

2. Waitr Holdings – Cheap Food Delivery Stock

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 – in fact, it’s one of the only companies in this sector to notch a profit in any quarter.

It’s entirely possible that Waitr will get acquired by a larger competitor, which would send the share price soaring. But even if it doesn’t, we think the company’s steady revenue growth will deliver gains for investors in the long term.

3. Quartix – Growing Fleet Management Provider

Quartix is one of the best UK small cap stocks in our opinion. This fleet management company provides subscription-based software that tracks vehicles and drivers. Before the COVID-19 pandemic struck, the company was adding customers at a rapid pace. Although that growth halted during the pandemic, Quartix is optimistic that sales will pick up again as people go back to work in large numbers.Quartix Chart

Importantly, Quartix could also be a big winner of the shift towards delivery. As more businesses work out their own delivery networks and existing delivery fleets get bigger, the market opportunity for Quartix’s software solutions only grows.

The company’s PE ratio of 30.8 reflects this future opportunity. However, considering that Quartix shares ended 2020 at virtually the same level they started the year at, we think the stock has plenty of room to run.

Your capital is at risk.

4. Smith and Wesson – Gun Maker with Political Volatility

For risk-tolerant investors who are willing to play with political fire, Smith and Wesson is worth a look. This US gun maker’s share price 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

In the short-term, Smith and Wesson could see further appreciation thanks to attempts at firearm regulations under a Democratic administration in the US. On the other hand, successful regulations could hurt the shares in the long term. So, tread carefully around this stock and treat it as a high risk investment.

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 – UK Brake Manufacturer

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 well 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, which should give the share price a jolt.

Your capital is at risk.

6. Novavax – COVID-19 Vaccine Developer

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, which would yield huge gains for Novavax investors. 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. Still, based on an estimate of potential revenue if both vaccines are approved, the current PE ratio could be as low as 8.

Your capital is at risk.

7. Unisys – IT Business Flush with Cash

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 incredibly low for a company that provides IT services, an extremely hot and fast-growing market sector.Unisys Chart

What’s even more exciting about Unisys is that it 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, which is music to the ears of long-term investors.

Unisys’s stock price has more than doubled since October. But with no signs of slowing momentum, now is potentially a great time to get in on this small cap IT stock.

Your capital is at risk.

8. Vista Outdoor – Outdoor Products for Hunting and Recreation

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 is also looking attractive thanks to its 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, making it attractive as an undervalued small cap stock.

9. Shield Therapeutics – Biotech Company with a Novel Drug

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. Such a deal would almost certainly give the stock a boost, and favorable terms could be a huge win for investors.

Shield Therapeutics isn’t yet profitable, but the light at the end of the tunnel is getting close. Once royalties start rolling in for its iron deficiency anemia drug, the company should report a profit. The company anticipates profitability in mid-2022, so then might be time to look at investing in the best biotech stocks!

10. Advanced Medical Solution – Poised for a Rebound in Elective Surgeries

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. The company is currently trading at a discount because of the drop in sales during 2020, but the vaccine rollout means that surgeries could resume at a regular pace as soon as this summer. Advanced Medical Solutions also acquired a key supplier in November, which could help the company cut costs and further improve its products.

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.

Are Small Cap Stocks UK  a Good Investment?

Small cap stocks are beloved by investors for their growth investors. Large cap companies like, say, Coca-Cola have already cornered global markets, so they don’t have much room to grow. The stock price can rise in response to increasing sales, but in general it’s rare to see double- or triple-digit gains from large cap stocks.

Small caps, on the other hand, routinely post double- and triple-digit annual returns. Often, these companies spend years developing a new product, and the shares can explode when that product finally makes it to market. Or small cap companies are able to move into new markets and act as disruptors. Small cap stocks are also acquisition targets for larger companies, which can send share prices flying.

The catch is that small cap stocks are also much riskier than their larger peers. If a small cap releases a new product, for example, and it has issues or doesn’t see wide adoption, then the stock can suffer badly. Many small cap stocks also have limited cash flow, so disruptions to their business can threaten bankruptcy.

How to Choose the Best Small Cap Stocks UK for You

One major thing that keeps many investors from trading small cap stocks is how difficult it can be to choose the right ones.

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. We recommend using a stock screener, which 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.

Once you’ve identified potential companies, look closely at fundamentals. Is the company profitable? If not, does it have a clear path to profitability? To get an idea of whether a stock is overvalued or undervalued, look at the PE ratio or price-to-sales ratio.

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?

All of these questions are important to consider when choosing the best small cap stocks for your portfolio.

Best Small Cap Stocks Stock Brokers in the UK

In order to buy small cap stocks in the UK, you’ll need a stock broker. Many brokers that have a limited selection of stocks only enable you to buy 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 quickly eat into your profits. We recommend looking for commission-free brokers whenever possible.

Trading tools are also critical. For finding small cap stocks, you’ll need access to tools like a stock screener, detailed fundamental data, price charts, and analyst research.

With all that in mind, let’s take a closer look at two of the top UK brokers you can use to buy small cap shares today:
