Summary
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.

| 0:12.0 | trend, systematic, fundamental. And so we've seen that as well in the trend in the trend space. |
| 0:19.0 | We've tried to be very careful in how we've implemented |
| 0:21.9 | ours, and I think our performance sort of a testament to that, but the risks that you highlight |
| 0:27.3 | are important as well. And so, you know, you've got to kind of look under the hood a bit at |
| 0:33.1 | what you're at what you're getting in these various offerings. |
| 0:41.2 | And that's one of the ways to manage the dispersion within the manager selection problem within liquid alternatives |

| 1:22.1 | understand that there's a significant risk of financial loss with all investment strategies, |
| 1:26.4 | and you need to request and understand |
| 1:28.4 | the specific risks from the investment manager about their product before you make investment |
