TTU151: What Comes After 60/40? Systematic Thinking, BlackRock Style ft. Jeff Rosenberg
Top Traders Unplugged
Why big managers are launching trend funds now
Jeff explains client demand, diversification needs, and ETF wrappers drove BlackRock into systematic trend ETFs.
Niels and Alan sit down with BlackRock’s Jeff Rosenberg to examine how the post Covid shift from too little to too much inflation is reshaping portfolios. Jeff explains why bond and equity correlations have changed, why fixed income is drifting back toward income rather than pure diversification, and how fiscal pressure and soft financial repression may influence rates. They explore what systematic really means at BlackRock, from trend ETFs and defensive alpha to market breadth and execution. The conversation ends with the rise of liquid alternatives, whole portfolio thinking and growing equity concentration risk.
