The Thornburg Investment Philosophy
Thornburg Investment has a clear mission: to preserve and increase the real wealth of our investors after inflation, taxes, and expenses. We seek to accomplish this through a range of equity strategies that redefine traditional measures of value and growth and through a family of laddered bond strategies that focus on quality, stability and minimizing risk over time.
Thornburg employs a comprehensive approach to equity investing, which is more inclusive than the traditional deep value or high growth approach to stock selection.
On the bond side, we have always had a highly disciplined approach of laddering short- and intermediate-bond maturities, seeking to provide both an attractive return and relative stability of principal.
