Tell me about your role at Thornburg, the management style you employ and the funds you oversee.

I am a portfolio manager for a lot of different funds with different strategies. I cover risk-free U.S. Treasury securities, asset-backeds, mortgage-backeds, the high-yield market and even some foreign markets and currencies. We take a very bottom-up perspective. We look at each individual security to manage the quantity, and the probability and timing of the cashflows. That way we can put each security on equal ground so that we're able to make a relative-value comparison across things that are pretty different.

Ultimately, we build our portfolios brick-by-brick from the bottom up. That's not to say we totally discount the larger, macro, top-down environment. It's just that our views are typically built from that mosaic process by looking at individual securities. We blend those together to create very well-diversified portfolios.

In the fixed income world, the returns are very asymmetric. You can either get zero or you get the return that the yield promises. If you're going to take a lot of risk, you should look at the stock market where you can make many multiples of your money.
