Buyer beware: Small companies
Shares in companies should come with a health warning. Usually, smaller, untested and growing firms present the the highest risk of failure.
But you can also enjoy the biggest rewards.
Take the example of Vodafone. A £1,000 investment in the little known spin-off from Racal is now estimated to be worth several million pound.
But the Vodafone's and Microsoft's of this world - that have grown from risky start up to dominate their particular industry - are few and far between.
