Strong businesses at attractive prices

The portfolio invests in stable trustworthy firms at attractive prices that can reasonably be expected to maintain or increase profitability over the long-term (at least five years). Strong finances indicate past success, high levels of profitability suggest current strength, and strategies that promise to differentiate companies in ways customers value promise future prosperity. The aim is to hold these shares for as long as they meet Share Sleuth’s criteria of trust and stability. Preferably forever.

Sometimes Share Sleuth may add shares in companies that are more susceptible to change. Economic downturns, competitors and poor managers push such companies around. They may perform well for years and then shock investors when conditions change. The trick to investing in susceptibles is to add them when they are undervalued, but strong enough to survive, and eject them when conditions are at their most favourable.

Portfolio and targets

The heart of Share Sleuth is a spreadsheet (below). It contains a simple financial model for every share in the portfolio, every target under consideration, and a decision engine that ranks the shares so the best long-term investments, stronger companies at more attractive valuations, are near the top

As these are Richard’s best investment ideas, he owns many of the shares. He doesn’t buy or sell shares on his own account within a week of writing about them and he informs Interactive Investor’s editor when he profiles a company he owns, in line with the Press Complaints Commission’s code of practice.

He won’t profit from short-term price movements that might result from something he’s written.

Long-term performance

Performance is measured scrupulously after charging £10 in lieu of broker fees for every transaction and 0.5% stamp duty on additions to the portfolio. Transaction prices are actual prices quoted by a broker including the cost of the spread. Uninvested cash earns no interest.

Over any five year period the portfolio should earn a positive real return and beat the stockmarket average as represented by a FTSE All-Share tracker fund with dividends reinvested, hopefully by a considerable margin. This is how Share Sleuth did in its first five years, to 9 September 2014.
