Book excerpt: For the past 25 years, investors in Ralph Wanger's Acorn Fund have not only enjoyed tremendous returns on their investments, they've also been treated to his wickedly irreverent reports. Known as the 'Dean' of Small-Cap stocks, Wanger explains how to invest in small, rapidly growing companies whose stocks represent good values. Emphasising the rewards of investing in the 'value' stocks of small companies over the 'growth' stocks of large companies, Wanger helps readers maximise profits and minimise risks - and survive the rough spells on the way to greater wealth. In the high-stakes world of the investment jungle, Wanger provides strategies for the reader to survive - and take advantage of - being the 'zebra in lion country'.
