Great British Stock Ideas! #29

1. AFC Energy (£AFC) – Charles Archer

Thesis: “AFC has developed proprietary ammonia cracking technology that produces hydrogen on-demand, on-site, at a fraction of the cost and energy consumption of alternatives…. At £100 million market cap, the market is pricing in substantial scepticism. That creates asymmetry. If AFC succeeds even modestly, the valuation should be multiples higher. If they succeed meaningfully… The downside from £100 million is capped at 100%. The upside if execution succeeds is 5-10x or more. For investors with appropriate risk tolerance, that’s exactly the kind of asymmetry you want.”

2. Angling Direct (£ANG) – Small Caps. Big Bags.

Thesis: “The UK’s leading specialist fishing tackle retailer… With international expansion off the table I can’t see this being a 10 bagger. The UK market already well penetrated and in future years will likely become saturated. That said, the customer data, infrastructure, and net cash position keep a “takeover at a premium” optionality credible.”

3. ASA International (£ASAI) – The Oak Bloke

Thesis: ASA International (ASAI) is presented as an undervalued microfinance institution that combines a high-impact social mission with exceptional financial performance. The investment thesis argues that rapid loan portfolio expansion across Africa and South Asia, bolstered by a strategic digital transformation, could drive profit growth beyond current market expectations and lead to a substantial share price increase.

4. B&M European Value (£BME) – Seb1991 of Value Investors Club

Thesis: “A cash-generative (FCF yield >10%), high-margin discount retailer with excellent store unit economics… Intrinsic value and price today are obviously disconnected… We are getting paid to be patient while UK LFL returns positive. New Mgmt are saying and doing the right thing. Overall, B&M represents a strong asymmetric risk/reward profile: undervalued, cash-generative, shareholder friendly capital allocation, along with a high margin of safety.”

5. Berkeley Group PLC (£BKG) – Contrarian Stocks

Thesis: “A UK homebuilder focused on brownfield regeneration… Berkeley is in dire straits just like the other homebuilders. However, downside is protected because of the balance sheet that management are using to break the market shackles by force (while maintaining £300m net cash for at least until FY26). A savvy capital allocation framework that is geared towards resharpening the business coupled with longer-term political and macroeconomic tailwinds results in a potential compounder at a trough, albeit high-looking, multiple.”

6. Colefax Group plc (£CFX) – Mpk391 of Value Investors Club

Thesis: “A solid, well run ultra-high-end home furnishings & interior design biz… With £3.77 in cash per share and an EV/EBIT of 3.1x, Colefax is cheap to peers and to its own trading history. The CEO is ~80 years old. Maybe his son takes over and/or maybe Colefax gets sold to PE, like so many of its peers. M&A history and comps suggest an EBIT multiple of 9.7x or better, or 122% upside in a sale.”

7. DCI Advisors Ltd (£DCI) – Beyond the Index

Thesis: DCI Advisors is presented as a deep-value opportunity trading at a discount to its net asset value as the company undergoes an orderly realisation of its luxury Greek real estate assets. The investment hinges on the sale of major assets to serve as a near-term catalyst for returning significant capital to shareholders and closing the valuation gap.

8. Emmerson plc (£EML) – South Sea Investing

Thesis: “Emmerson is a potash development company. While a strong business case can be made for investing in potash, the potential upside here is from Emmerson’s circa £1.6 billion claim against the Kingdom of Morocco. Against Emmerson’s £29.11 million this would be a huge return on investment if successful and could deliver asymmetric returns.”

9. Greggs plc (£GRG) – CM Capital Research

Thesis: “If Greggs manages to grow its like-for-like stores above the rate of inflation, and keeps opening at least 150 stores for the next decade with a ROCE above 15% on the new stores, then there is an investment case. Both the bull and the bear case are a possibility with Greggs, and the cost of living crisis creates unpredictable downside risk… The risk - reward appears skewed to the upside, but the catalysts that need to material are largely related to price-increase ability and market saturation - both relatively difficult goals to achieve.”

10. Headlam (£HEAD) – Dismissed Europe

Thesis: “UK’s number one flooring distributor… Our view is that HEAD, at the current valuation and over a 3-5-year view, offers an attractive risk–reward. Beyond the potential upside for minority shareholders, the company may appeal to an operationally experienced sector peer or private equity investor seeking a contracyclical entry, whether for parts of the business or the group as a whole.”

11. IG Design Group (£IGR) – Dismissed Europe

Thesis: “The UK leader in design, manufacturing and distribution of various celebration and creative products… Let’s assume that IGR performs in line with management’s expectations and closes FY29 with +$300m sales and $15m of EBIT (to simplify, we assume no re-instated dividend*, a conservative assumption)… If the market then assigns IGR a 10x EBIT multiple, this implies an EV of $150m and a market cap of $190m ($40m of “net excess cash”), corresponding to $1.93 per share, or 145p (a potential upside of +215% and a potential CAGR of 42%).”

12. International Public Partnerships (£IPP) – Value Zoomer

Thesis: “INPP holds essential, low-risk public infrastructure backed by long-term, inflation-linked government contracts. Right now, the stock is trading at a 15% discount to its book value, with a high average discount rate of 9% baked into that valuation. We are getting a safe, uncorrelated 9% yield just to wait. The upside is clear, as either a return to normal interest rates or structurally higher long term inflation should both benefit the stock in different ways. The downside is limited because the cash flows are so secure.”

13. Judges Scientific (£JDG) – Leeder Capital

Thesis: “Judges has been a great compounder over the last 20 years, which has been enabled by a highly scalable business model, attractive industry dynamics and a skilful capital allocator at the helm. Current macro headwinds have potentially created an attractive entry point to this great business if you believe the risks mentioned including; product quality issues, competition and leadership transition don’t materially alter the long-term prospects of the business.”

14. Metlen Energy & Metals (£MTLN) – The Modern Investing Newsletter

Thesis: “The business can be broken down into Energy, Metals and Infrastructure… The long track record, coupled with recent insider buys and several potential catalysts ranging from a potential METKA IPO to potential deals regarding critical raw materials (such as gallium) make Metlen attractive from an investor’s perspective. The recent sell-off provides a clear setup for long-term returns and from a risk standpoint… The exposure to Greece can be seen as both a risk and an opportunity.”

15. MTI Wireless Edge (£MWE) – PPInvest’s Substack

Thesis: “An established, diversified Israeli technology company with a history of over 50 years in the development and delivery of radio frequency and communication solutions. The combination of growth potential, solid dividend yield and active share buybacks offers an attractive overall package for the patient investor. Current price 40 GBp. My price target for the next 3 years is 87 GBp (+113%).”

16. Panthera Resources (£PAT) – Case Research

Thesis: Panthera Resources is undervalued, as the market currently implies only a 14% probability of success for its $1.58 billion arbitration claim against the Indian government for the expropriation of the Bhukia gold project. As legal proceedings advance through the Permanent Court of Arbitration over the next two years, the stock offers a potential significant upside based on a probability-weighted assessment of the eventual award.

17. Relx (£RELX) – Multibagger Radar

Thesis: An “Anglo-Dutch giant specialised in science, law, risk analytic and exhibition (the last one is real… If RELX sustains ~10–12% EPS growth (in line with recent trajectory and consensus) and holds anything like a high-20s to low-30s multiple, you don’t need heroics to get 2–3× over a cycle; the math of compounding plus buybacks does the heavy lifting.”

18. Rightmove (£RMV) – Mr Blonde

Thesis: “Rightmove has operated as a utility for the UK property market over the last decade… We are long Rightmove (RMV.LN) at £5.40, with a clear path to 30-50% upside over the next 12 months. The thesis rests on an asymmetric risk/reward profile created by a panicked market reaction to the recent Capital Markets Day (CMD). The trade is simple: You are buying a dominant, high-margin monopoly at a depressed valuation (18x P/E), with a call option on a renewed takeover bid from REA Group.”

19. Sanderson Design Group (£SDG) – Dismissed Europe

Thesis: “A UK-based interior design company engaged in the design, manufacture, and marketing of wallpapers and fabrics… At the current share price, the implied FY29 EV stands at just £14m, versus potential EBT of +£10m. We estimate that Brands and Licensing could justify an aggregate EV/EBIT 12x in a normalized environment, implying a FY29 EV of c.£120m and equity value of c.£140m. On the current share base (72.1m), this equates to c. 200p per share or 4.5x the current price, an implied CAGR of 64% over three years, or 35% over five years.”

20. Surface Transforms (£SCE) – Small Caps. Big Bags.

Thesis: “The UK’s only manufacturer of carbon-ceramic brake discs for automotive and aircraft applications… The technology is genuinely superior, and customer support demonstrates real demand for their products… For risk-tolerant investors with conviction in the management team’s ability to execute, the potential rewards could be substantial if the company achieves sustainable profitability.”

21. Wise plc (£WISE) – 100 Bagger Hunting

Thesis: “UK-based financial technology company… with the mission of making international money movement faster, cheaper, and more available. Instead of relying on the traditional banking system, Wise has built its own network of direct connections into local payment systems worldwide… I believe in the next 5 years, we should be able to see EPS growing at 15% per year. I consider no multiple expansion in that story. Continued investment will drive growth in active customers and revenue, which eventually will lead to continued profit growth.”

22. Wise plc (£WISE) – CM Capital Research

Thesis: “A company within the cross-border payments industry… Wise has been a player that has disrupted major incumbent players while being very profitable. The “war” that has taken down Wise’s revenue growth and profitability, has been self-inflicted to gain market share and build a moat… There’s a real risk, though, with stablecoins. However, the on-ramp and off-ramp costs are very high… After all, what people want are cheaper, faster, and safer money transfers. And to do that, Wise is the best option.”

23. Zenith Energy (£ZEN) – Case Research

Thesis: Its market capitalisation significantly undervalues its legal claims against Tunisia, headlined by a $572.65 million ICSID arbitration. By valuing the core operating business at zero to provide a margin of safety, the thesis relies on the enforcement of these legal awards and the subsequent distribution of extraordinary dividends to realise a projected 1,953% upside over a five-year horizon.
