The easy choice here is the Vanguard Health Care Fund, a no-load with low expenses and a superb performance record: 16% a year since inception in 1984.
Berry likes the similar Eaton Vance Floating-Rate Fund, yielding 1.9% after expenses of 1.8%, for its "steady performance and proven management" and the no-load Fidelity Floating Rate High Income Fund, which is returning 2.9% after expenses of 0.9%.
