The manager

The Puma AIM IHT service is managed by Puma Investments, part of the Shore Capital group.

The investment director is Justin Waine, who has been investing in small and medium-sized companies for 21 years. Mr Waine started his career as a small company broker at Cazenove, before joining Polar Capital to launch a European long/short hedge fund focused on small and medium-sized companies. He joined Puma in June 2014 and launched the IHT portfolio in July 2014. 

Mr Waine was attracted to Puma’s long-term investment style. He had analysed AIM extensively and realised the market had changed enormously. In his view the market no longer included just speculative high-risk businesses but also plenty of long-term mature ones, which are the focus of this portfolio.

Investment strategy

The portfolio targets mature AIM businesses screened across three key metrics: quality, growth and value. Capital preservation is also a priority.

Mr Waine focuses on two kinds of companies: firstly, family or founder-owned, as they often are on AIM for Business Property Relief reasons; and secondly companies controlled by a successful entrepreneur. Long-term buy and build holdings are also considered.

Whatever the company type, Mr Waine seeks businesses with potential returns above the cost of capital. Discounted cash flow analysis is done for every company using Puma’s own internal metrics and analysis and a fair value price target is set.

The portfolio seeks companies with decent margins, sales and profit growth and a sensible balance sheet. Having a cheap share price isn’t the most important factor for Puma. A strong balance sheet is more important, in their view. The firm looks at companies with a market cap of at least £50 million.

The targeted hold period for investments is three to five years but longer positions will be considered if the company continues to improve and valuations remain sensible. Holdings will be sold when companies reach what Puma considers to be an appropriate fair value or if the investment team change its view on a stock. Puma believes it is better to exit a position sooner, even if this results in a loss, than potentially incur a greater loss later on. 


Investors will each hold a portfolio of around 20-25 shares. This is a relatively concentrated portfolio when compared with its peers. Each portfolio aims to closely mirror the investment director’s own portfolio but individual portfolios will vary.

The portfolio seeks to be fully invested in AIM shares, with only a small cash position (approximately 2-5%). The average position size is 2% to 6%, with no position expected to be greater than 10% of the portfolio.

The portfolio avoids early-stage companies such as loss-making miners, biotechnology companies and high-growth concept stocks, as well as small companies with a market cap under £50 million.

Currently, the average market capitalisation of companies in the portfolio is £508 million (December 2020). Companies are typically bought with a three to five-year time horizon.

Risks – important

This, like all investments available through Wealth Club, is only for experienced investors happy to make their own investment decisions without advice.

AIM IHT portfolios are high-risk so should only form part of a balanced portfolio and you should not invest money you cannot afford to lose. Before you invest, please carefully read the Risks and Commitments and the offer documents to ensure you fully understand the risks. 

AIM stocks can be hard to sell, particularly at the smaller end of the market, and can be illiquid. AIM shares can be very volatile especially if the market falls sharply. The difference between the buying and selling price of AIM quoted shares is often wider than the spread for shares listed on the main market.

Tax rules can change and benefits depend on circumstances. Eligibility for BPR is assessed at the date of death and will depend on the companies in the portfolio remaining qualifying.  Broadly speaking, you will need to have held a BPR qualifying stock for at least two years and still hold it on death to qualify.

One further risk is that this is a more concentrated portfolio than other IHT portfolios with around 20-25 stocks, placing more importance on the stock-picking abilities of the manager. The portfolio centres on Justin Waine so there is some key man risk.

Treasury review

A previous Chancellor requested a review of IHT to simplify the tax system. A report was published in July 2019, but this has not yet led to any rule changes. Please remember, tax rules can and do change and benefits depend on circumstances.

Our view

The service targets mature AIM businesses screened across three key metrics: quality, growth and value. Notably, the portfolio steers clear of the AIM market’s increasing number of early-stage businesses, biotechnology businesses, and high growth concept stocks. 

The resulting portfolio is spread across a variety of sectors and has a bias towards businesses operating within Construction and Materials, Electronic Equipment, and Industrial Services sectors. The Investment director Justin Waine is very experienced and has a defined criteria for investee companies. There is some crossover with other AIM ISA portfolios as you might expect, but some different holdings too, which could provide diversification.
