TCW seemed content with the arrangement and did little to tie its managers' fates to the company as a whole. Few of them, for example, received significant stakes in TCW. That bred frustration in multiple generations of standout performers, who viewed corporate executives (some of whom did receive ownership shares) as getting rich off their toil.So it went for Gundlach, a bona fide investing star who, by the end, oversaw about 70% of TCW's assets, some $70 billion, putting him in charge of one of the biggest pots of money in the country. Gundlach didn't just generate steady returns; he avoided the blowup of the century. A specialist in mortgage-backed securities, he publicly warned in 2007 that "the subprime mortgage market is a total, unmitigated disaster, and it's going to get worse." He invested accordingly, not only delivering positive returns in the blighted year of 2008 but also earning himself a growing role as a media sage. His ego grew along with it.There are few people like Jeffrey Gundlach in the mutual fund world -- or in any world. A former rock-and-roll drummer, Gundlach, 50, is a math whiz (but not a quant). He views everything in binary terms: Either you perform to his standards or you don't, and he won't hesitate to let you know which category you fall into. Nor is he shy in articulating his view of himself. "I was by far the biggest revenue generator at TCW, by far the biggest performer," he says. "I created $4 billion in value for clients in '09. If telling you that is self-promotion, so be it. It's just a fact."
