What are the best penny stocks for UK traders and investors to watch?

What is a penny stock?

A penny stock is a unit of common stock that trades with a low share price: below £1 in the UK and below $5 in the US. They’re also referred to as penny shares. The companies will also have a lower market cap: under £100 million in the UK and under $300 million in the US.

These stocks are regarded as a more speculative investment because they’re geared for growth, with many penny companies yet to generate noteworthy income.

Best UK penny stocks to watch

These are not necessarily the best performing penny stocks, with several having seen their share prices decline over the past year. This list shouldn’t be construed as financial advice.

Many of these penny stocks have been hit by the wider market downturn since the start of 2022. However, while their share prices may have fallen in recent months, this is not necessarily a reflection of their true value.

And with interest rates elevated, it is true that growth is becoming more expensive, increasing the risk of investing in many penny stocks. Those on this list could well see further falls.

Shoe Zone

Shoe Zone saw significant growth by dint of its value offering during the pandemic. To date, it’s sold nearly 17 million pairs of shoes at an average of just £12 per pair.

In full-year results to 30 September, revenue rose by 6.1% year-over-year to £165.7 million, driven by a strong back to school period. Accordingly, adjusted profit before tax increased by some 47% to £16.5 million. For context, digital sales now represent 18.7% of group revenue, after significant investment in its digital platform.

CEO Anthony Smith enthuses that 'Shoe Zone had a very positive year, with strong and consistent results throughout the key trading periods, particularly in the second half, with strong peak summer and Back to School trading.'

Kodal Minerals

Kodal Minerals agreed a $117.5 million contract with Hainan Mining in January 2023 to develop the former’s flagship Bougouni lithium mine in Mali. After a near year-long delay, the company has now acquired the funding and plans to start production by the end of the calendar year. Kodal remains in competition with ASX-listed Leo Lithium to be the first lithium miner in Mali.

Of course, lithium prices remain depressed. But over the longer term, the stock could deliver handsome returns to investors with a reasonable risk appetite.

Harland and Wolff

In late 2022, Harland & Wolff was awarded ‘preferred bidder’ status as part of a team effort for a £1.6 billion shipbuilding defence contract. With the contract now set in stone, PM Rishi Sunak publicly visited the company on-site in Northern Ireland in 2023, and 2024 could be HARL's transformational year.

The company is also developing gas storage at Islandmagee which has shot up the political agenda – and the worrying judicial review concerning the project has ended in its favour.

On the other hand, HARL shares have fallen sharply due to its cash and debt position. The company is currently in negotiations with lenders including UK Export Finance over long-term debt restructuring and further funding. The company is also considering a sale of the Islandmagee asset.

DG Innovate

DG Innovate more than doubled in December when it announced a board restructuring involving the appointment of three new directors; all of whom are former Tesla executives.

Peter Bardenfleth-Hansen has been instated as CEO, while Christian Eidem and Jochen Rudat have come on board as executive directors. The business, which specialises in electric mobility and energy storage, also secured £2.4 million in new funding through convertible notes.

Shares in the company have nee drifting downwards due to lack of news, though this may change in short order.

Abingdon Health

Abingdon Health is becoming a popular penny share after launching its patented Salistick pregnancy test in partnership with Salignostics. The test is the first to use saliva rather than urine and there could be strong growth potential; 12.5 million pregnancy tests are used in the UK every year, while the global pregnancy test kits market is expected to reach $2.28 billion by 2028.

The company is selling the test directly and also through Superdrug and Tesco physical sites and online. In half-year results, revenues rose by 117% to £2.4 million, and the company is focused on developing a cash flow positive position. Gross margins also improved from 25.9% in 2022 to 53% by the end of 2023.

Poolbeg Pharma

Poolbeg Pharma is working towards its first partnering transaction for flagship POLB001 after a recent successful human challenge study, alongside further positive trial results in January. It’s also developing two more promising treatments — POLB0002 for respiratory infections, and POLB003 for melioidosis.

Encouragingly, the company recently appointed Brendan Buckley as an Independent Non-Executive Director. Buckley has been an advisor since its founding and was a member of the Board of Directors of the Irish Medicines Board, chairing its Advisory Committee for Human Medicines.

Golden Metal Resources

Golden Metal Resources' flagship Pilot Mountain project is the largest undeveloped Tungsten deposit on US soil — ideally situated for power, water, skilled labour, transport, and pro-mining politics. And the asset is 100%-owned.

The US is currently entirely dependent on third countries for tungsten, and its largest import partner remains China, which controls 86% of global tungsten exports. From January 2026, the US Department of Defense is banning imports of the metal from China — and China recently banned the export of several critical minerals including some forms of graphite.

GMET has been pursuing non-dilutive US government funding for months, which could yield fruit should China choose to impose a Tungsten export ban. The company is on the verge of launching a drillling campaign at its flagship asset.

Ondo InsurTech

Ondo InsurTech has developed the ‘LeakBot,’ a patented tech designed to dramatically reduce water damage, which should in turn significantly decrease insurance premiums and payouts.

It’s signed a go-to-market channel partnership to accelerate LeakBot deployment in North America with titan WNS, as well as deals with leading companies in Denmark, Sweden, and New Zealand.

More recently, ONDO has signed an affiliate partnership agreement with Waterwise, giving it much wider UK exposure — alongside a new partnership with US-based PURE Insurance and South West Water.

Blencowe Resources

Blencowe Resources' Orom-Cross project in Uganda is widely regarded as a potentially world-class graphite deposit. The company has been awarded a £5 million grant from the US International Development Finance Corporation as a first step towards a larger contribution that would be needed as part of the £62 million required to build a production plant.

Some of this funding has already hit the miner’s accounts, and recent SPG test work has come back with exceptionally positive graphite purity results. The company could soon benefit from further US funding as China has tightened graphite exports.

OptiBiotix

OptiBiotix Health operates in the progressive domain of biotechnological research, with a focus on the modulation of the human microbiome.

The company’s R&D approach leverages pharma-grade platforms specially targeted at the food and dietary supplement markets. Its extensive portfolio includes 65 patents across 17 families, 8 strain deposits, and more than 28 trademarks.

The current flagship is SweetBiotix — a patented sugar substitute which is classed as a dietary fibre and attached to several health benefits. The company signed a significant manufacturing agreement with a US partner in September 2020, guaranteeing annual milestones and royalties on sales with blue chip companies including Kellogg’s, Nestle, and Coca Cola.

Past performance is not an indicator of future returns.

Risks and rewards of penny stocks

1. The share prices of penny stocks can be volatile, either as a result of lower liquidity or because they are sensitive to news and market developments
2. Penny stocks can turn into a huge success or an utter failure overnight: winning or losing one contract or the level of success of a new product, for example, can decide their future
3. Many penny stocks have no track record and it is not uncommon for them to have no assets, operations or revenue
4. Products and service offerings are often still in development and yet to be tested in the actual market
5. News coverage and analysis of penny stocks is harder to come by compared to gaining insight into larger, more popular stocks
6. Penny stock companies are more likely to raise equity from investors on an ongoing basis, as it gives the business a way of securing vital funds for growth if traditional lenders refuse to provide it
7. When trading on penny stocks with us using spread bets or CFDs (but not with share dealing), you’ll do so using leverage. Leveraged trading comes with a high risk, as both profits and losses will be amplified. Always take steps to mitigate your trading risk.
