The Economist wonders if the so-called Yale model, an aggressive use of conventional and alternative asset classes, will shine as brightly in the years ahead as it has over the past quarter century.

His strategy, explained in his 2000 book Pioneering Portfolio Management, has been hailed by many as the only way to fly for institutional investors. Individuals, too, can also learn a thing or two from Swensen, argue his supporters.
