Our Company

The ShareMaestro system has been developed by Glenn Martin, who has over 30 years' career experience in Financial Services, latterly on the Executives Committees of the investment banks Schroder Salomon Smith Barney, Cazenove and JP Morgan Cazenove. Glenn has won several industry awards and is featured in Debrett's People of Today, which includes the UK's most influential and successful people. Following the success of ShareMaestro, Glenn was commissioned to write How to Value Shares and Outperform the Market (Harriman House 2011).

Glenn Martin developed the first version of ShareMaestro in 1994, when he became increasingly disillusioned with the simplistic market valuation approaches adopted by investment analysts. These approaches normally attempt to value shares in isolation from the current and prospective economic environment. The Nobel Prize-winning Black Scholes algorithms calculate the value of equity options from both the characteristics of the underlying equities and from the economic & market environment. Similarly the proprietary ShareMaestro algorithms calculate the value of cash equities from the characteristics of the equities and from economic & market factors. Having seen ShareMaestro valuations repeatedly proven reliable, often against the forecasts from the City pundits, Glenn decided to develop ShareMaestro for use by the serious UK investor. The ShareMaestro FTSE100 valuations have been validated from the start of the index in 1984 and have been shown to be robust. See FTSE 100 Track Record. ShareMaestro Limited is a UK-registered Limited Company, registration no.06002320.

Risk Warning

ShareMaestro valuations do not constitute investment advice from ShareMaestro Limited, which is not regulated by the FSA. You should read fully the ShareMaestro Terms and Conditions and the User Manual before purchasing and using ShareMaestro.

Past performance is not necessarily a guide to future performance.
