Glenn Greenberg is one of those investors with a fantastic track record, but that seems to fly under the radar. Greenberg's approach to investing is based on value and cash flows, which has produced fantastic results since the trader started investing.
Greenberg's fund, Chieftain, returned 18% annually after fees over the 25 years from 1984. In the decade after the financial crisis, when he split from his partner and set out independently, the investor produced around 16% per annum returns.
The investor started his career with JP Morgan. When he began in 1973, it was the country's largest and most respected money management firm. However, as Greenberg observed, its approach to investing clients' money was haphazard at best.
