One reason for the growth is that while money market funds and most other investments tanked in 2008, stable value funds delivered between three and five percent returns, as expected. “During the worst recession in a generation, stable value performed as designed, providing plan participants with regular, positive annual returns. Virtually no other asset class can make that claim,” says Jim King, managing director and client portfolio manager for stable value at Prudential, in Woodbridge, NJ, the U.S. market leader with more than $112 billion in stable value assets under management or wrap.
